@Dj-Jon-E-C: Is some satisfaction when you got something you made yourself. haha I have put glasses on when soldering
@benjyboba: I love this because I know its true too, diy means, you can build things the way they would be built if you dedicate to doing it right. I heard a pair of speakers many years ago that I have never seen since. 4 ways 6 drivers, sealed bass. had round horns diffusers, mid ranges and rectangle horns. The sound quality of those speakers were leagues ahead of anything I ever heard anywhere. I expect they were made by engineers who knew what they were doing. I'd love to try and replicate a pair using old oringinal drivers or even matched modern drivers to hand off to the other frequency for a sealed bass. So basically the drivers work best in their own ranges and work together acoustically and dispersion. I don't know entirely what I am on about but believe me, there was something very special about the speaker design and it blew my mind. Sweetspot everywhere, speakers totally vanished. Left with a full 3d illusion that was so believeable, it was actually really there in my mind in the location. Expressiveness was on a level of insanity. My guts turned to jelly, my pupils dilated, I stood up instantly when it was turned up loud in shock. A true musical connection. It wasn't driven by named components, it must have been built by studio engineers with no compromise. Not soon but one day I want to try and see how far I can take some old speakers with the right driver combinations, cross over slopes and try and get it best I can. I have a lot of learning but I do understand that human perception matters and good speakers and drivers work together with smooth matching patterns and account for on axis and off axis sound. I think they did the best equipment some 30-40 years ago. They cared when they made them and pushed the limits and built over powered amps etc that has good control. Today and in the future, it went to mass production and marketing. In other words, cross overs are not designed for the exact drivers. The impedence needs good matching with the drivers and matching pairs. Good speakers match but I suspect the system I heard was cherry picked for the best parts. The thing is, you can tune things. I do and I don't know what I am doing, at least I know what the aim should be. I suspect that most people would die of shock on the spot if they heard what I did. Heaven, reality and priceless illusion, pleasent and could 100% hear everything like it was played by itself. I love music and sound to not try it one day. I wonder if you could build a pair of speakers to those standards I heard.
@Rick-l4w: Best Kept Secret on the Market
Focal Utopia MAIN 212 Active Speaker System
Amazing BARGAIN !
@allanmoorhead9492: For a few thousand dollars you can buy a pair of good quality studio monitor speakers, which are bound to be good enough for most listeners, and probably better engineered than any home loudspeaker builder ever could.
@ravington666: Uhh..no thanks I'll just buy some for now and save building my own for a retirement project !
@EbonyPope: "Young people don't know how lucky they are". Well young people may be lucky that prices are so affordable today but what does it matter if they don't care? Very few people actually still have a good Hi-Fi Stereo at home.
@madmad8582: I have a pair of Leeks and sadly who ever owned them over powered them and they where toast and was unable to find new drivers or recone kits for them sadly they still sit in my closet they a look like Rank Wharfdale speakers .
@madmad8582: I built my own speakers from scratch using the plans from Electro Voice , plans made bye Paul Klipsch on the Aristocrat Folded Corner speaker or corner Horn , To me these speakers have proven them selfs to be true Hi Fi speakers made in 1955 these speakers where crafted bye Paul Klipsch He also created his own speakers from scratch as well, and he used Electro Voice Drivers in his speakers and they where nothing but amazing . Electro Voice is the voice of the theater even till this day they continue to be the Best Speakers in the world and are used at Live concerts to theater sound , and are built to be hanged up on a rack on top of each other on either side of the stage , Electro Voice also had a 30 inch woofer and once was the biggest woofer in the world , now they use mostly the 18 inch EV musical speakers for there stage monitors these speakers are very powerful , some of them have built in Amplifiers , and others can be powered bye a EV rack mounted Amplifier they are MONO and to be in Stereo they need another EV Amplifier , EV also makes there own mixing boards as well ,and Microphones yes Microphones and they where the first thing EV crafted before speakers way back in the day even Elvis sang through EV microphones why is that EV is the Best Microphone ever made . put it this way have you ever seen a chrome speaker basket well EV use to Chrome there Drivers , and where very cool to look at the first series of EV woofers and Horn driver where chromed so nice why they are the very best speaker ever made . next to some English speakers like Tanoy and Wharfdale , i did have in my shop some Gold Tanoy's and sold them for 800.00 dollars every once and a wile I do come across some very nice speakers , the other day I found a pair of Sylvania book shelf speaker for 24 dolors researched them on the inerwebs and they are worth 500.00 dolors and I am restoring the finish on them they have a few nasty scratches on them , like I say I do a lot o hunting for Old speakers from the Salvation Army and others sources it started out as a hobby now its more like a job and is why I am the Speaker Doctor , and I bring Old Speakers back to life .
@mickbenq: sorry but were do i get the money from...
@jasonedwardledburynewzeala9897: What amp are you ising
@AudioMasterclass replies to @jasonedwardledburynewzeala9897: For my music studio, Fosi V3. For my video studio, 2 x Fosi V3 mono. For my home cinema, nothing. It died last week and I haven't replaced it yet. (Not Fosi).
@Tullimonstrums: My stereo speakers are the BEST stereo speakers in my living room!!! ...because I designed and built them myself! ...with some guidance from the Melbourne Audio Club. Speaker design is about knowing what you like in a speaker, really listening and thinking about audio and musical genres, and then picking your compromises, as there is no perfect speaker! Designing your own speakers is very educational, you will get a new appreciation for sound and develops into an awesome hobby. As a newbie, picking the drivers was very challenging, so many out there. I found SB Acoustics are leaders in value drivers. If you want really high-end, then Seas has many drivers. Next set of speakers will use miniDSP, to experiment with crossovers and slopes before building passive crossovers. Enjoy!
@habana7638: My first homemade loudspeakers (1976) were ITT Schaub-Lorenz BK 4-70s. There's still a photo of them online at the Radio Museum. They were fantastic speakers, but big..
@AudioMasterclass replies to @habana7638: Big is best.
@habana7638 replies to @habana7638: @AudioMasterclass Yes, definitely if you want to hear decent bass. Those things were only 40 watts and 70 watts max. (Concert speakers) I've always regretted getting rid of them. I made everything myself back then and still do. You can always buy ...
@hartmutjahnel73: :-) it seems to me, you told my story in speakerbuiding. thank you for this video and yes, I have the best speaker in the world.
@Chris.Davies: I find the best policy is not to make your own speakers. This is a policy I'm violating right now, by building and 3D-printing the world's smallest transmission line speakers fitted with Audio Nirvana Super-Cast 3" full range drivers. Each unit is bracketed by two 25mm 11-layer marine Birch ply panels, and the surprising thing is that they reach all the way down to 130Hz, and with the transmission length carefully curated, they punch so far above their weight, that when I first tested them, I was convinced there were another set of speakers running alongside them.
But even these teeny tiny speakers have consumed over 50 hours to build, and the cost of the speakers was very high, but it's so long ago I forgot how much. :P
I find that by FAR the best policy on hand-made speakers is to buy them from the person who made them. They have undoubtedly documented their build, and so they will proudly provide a bunch of photos and details of their build, along with technical specs, and measurements.
Because the vast majority of people will never even LOOK at a set of hand made speakers, you will buy them for practically nothing. I have a pair of genuine ProAc Response 2.5s which I basically stole from the owner, as they suffered some cosmetic damage during our first big earthquake, here in Christchurch. Based on the (frankly bonkers) performance of that set, I purchased a set of hand made 2.5 Response clones for $500 from the guy who spent 250+ hours making them. The (correct!) Scanspeak drivers ALONE cost over $1,200 NZD, making the deal an absolute no-brainer.
And the kicker? They actually beat the genuine items in clarity and bass response. Each speaker weighs 63 kilograms, or 140lbs. The hardest part of the process was finding a viable way to ship them 1,000km!
More recently, I have paid just $250 (last week in fact!) for a pair of hand-made cabinets for the drivers from a set of DB Polaris 610s. Each 17kg speaker features 25mm thick solid oak panels, and a protruding 25mm thick solid cherry baffle. They are achingly beautiful. The creator took the crossovers apart, and replaced all the internal copper wiring with pure silver. He used sheeps wool for damping internal reflections and re-tuned the length of the rear-facing port. I conservatively estimate the drivers are worth at least $600. The wood panels alone would have cost at least $400 - and maybe much more! The silver wiring adds another $100. Then there is the 150 hours he put into them, along with the 100+ photos of the whole 6-month build process.
These things almost match the ProAc clones, and are by far the best near-field speakers I have ever owned. When driven by my triple mono-block ZA3 system (passive sub) the results are shocking, to say the least.
So yeah - save yourself the trouble, and buy them from other people for nix!
@AudioMasterclass replies to @Chris.Davies: I suspect you’ve enjoyed your adventure.
@creaversum: Well my self build Klipsch Cornwall blows the originals Klipsch Cornwalls away! Higher quality components than the factory stuff does it.😎
@kjella.johansen1402: Brilliant input!
@msdxyz: Back in the UK christmas 1982 I went to the KEF factory in (Kent?) and bought a Concerto KEFKit it had the cab dimensions, hauled them back to San Francisco and instead of particleboard I used this new-fangled MDF board heavy as hell, but the bass with the oval B110's!! I pulled them out the other day replaced the tweeters and Voila the best speakers in the world 50 yrs later! As a bonus I found some toys my young kids had lost in the bass ports, they also liked to press in the tweeter domes that I would have to suck back out with a reversed turkey baster tube.
@MrAtares: More than ten years ago i have the aide to build my speakers even knowing that maybe is easy to buy them. I spend a lot of money and time in research for the best parts and until today. You just remain me that all the parts still in boxes in my garage.
@tedanderson5528: Built my pair 15 years ago and never heard their equal 😎 The Voigt design is life changing : )
@MD-ww4bh: +1 for Wilmslow Audio. I put their LS3 plus drivers and crossover kit in my own cabinets, they are superb speakers. Imaging is excellent, bass is present and the mids are stunning.
@Preciousday101: Effort = enthusiasm = engagement.
@Gemo6132: I love how you hold your laughter, Sir😂..and love your vids
@joebass5163: I just built a pair of Siegfried Linkwitz LXminis. Best speakers in the world!
@stevenwilliams6258: For those wanting to understand where equations come from, for sealed, ported, horn, etc , the book Acoustics by Leo Beranek is fantastic. It starts with a point source and grows the concepts into the various designs. I put the equations into a spreadsheet so I could easily adjust parameters to get the desired damping, response including expected peaking or variation.
Many books or booklets have graphs for crossover inductors and capacitors for basic configurations. For a more thorough solution for particular drivers, I used Madisound in the USA. At the time I thought the service was reasonable and I built it using a crossover PCB.
I built some very nice sounding speakers with rule-of-thumb sizing.
My last speakers used Scan Speak drivers - Revelator and Illuminator series.
I expect very good results would come from Dayton Audio drivers, though I have only studied their data sheets.
I the 70's I got two 10-inch failed drivers with cast iron frames and fabric ribbed edge surrounds. They sounded great in a 3-way. I prefer 3-way speakers but modern mid-tweeter drivers sound decent at 700Hz crossover in a 2-way.
My ScanSpeak 7-inch Illuminator with a good ScanSpeak upper driver sounds quite good, though, thunderous bass won't come from that so I have a sub woofer.
Building the box: make it strong! You don't want the box to contribute resonances. Screw and glue every 6 inches and 3 inches on removable panels. One builder used 1-1/2 MDF. I get good results with internal panel braces and panel to panel bracing. All corners braced. I haven't gotten into curves, just boxes though I did design and build a mid range horn but used piece-wise linear approximation of the vertical and horizontal flare. Everyone has their build ideas.
Well worth the effort.
@AudioMasterclass replies to @stevenwilliams6258: Speaker-building comment readers will do well to read the above.
@zen_dac: I just recently looked into building a pair based on the LS3/5A model. I already did this in the early 80s (long story) with great success. A couple of days ago I watched this from KEF: https://www.youtube.com/watch?v=qzcMLB-kEiY
I have a pair of LS50 meta speakers arriving next week. There is no way I can compete with that level of engineering
@CORVUSMAXYMUS: Great logic.
@robertmeyer7664: I love the way you explain things and a great sense of humor
@Justwantahover: I built my BSITW by having an open 10" coaxial driver on top of the box with a 10" woofer in the box. The coaxial was built up from a 10" bass/med (PA) driver and a mini car 1" dome tweeter that fits inside the bass/med voice coil tube. It's time aligned. The 1" dome has a > 1/2" hole in it so there is only > 1/4" of the dome around the edge. The bass/med cone also has breather cutouts (thin radial banana shape holes) in two layers. It's a 4"diameter set and an 8" diameter set of banana cutouts. It simulates a whizzer cone as part of the main cone (that's in phase) and an 7" simulated free edge cone.
The med range is free and clean like never before! My whim is to have NO ENCLOSED CAVITIES from 300 hz upward! 😂 The best med to treble sound I ever heard (and there is no going back). It's point source and dipole for sounds that come from nowhere. Some bass is fed into the large open driver and it works with the woofer for way better bass. The open cone gives the kick that "puh-huh" that you hear on a real kick. Sensational bass!
The 10" woofer is on the bottom panel (in the box) firing down onto the floor. There is an annular radial bass vent around the top of the box. Witch is a tall plastic flower pot (round and up-side-down). 😂 It's drastically braced with a bunch of 3/8" dowel pieces across inside (in triangles) like the star of David. 😂 And there is a wood bottom plate for the woofer, at an acoustic height above the floor (1"). The top radial bass vent also incorporates a large 6" diameter bass vent tube running down 7". The top plate of the box makes the radial bass vent and is the base for the top open coaxial.
I designed the crossover by the f*ck around and find out method. But I do have reference bought speakers too. That's for course adjustment and I change the sound very slightly, to my liking. I happen to not like my > 2 grand (AU) B&W 706 speakers, but they are extremely helpful with the course adjustment. That's important cos it's a start! Bass level changes drastically in my room so it's hard to tell the right bass level without reference speakers. 😂 A must have if you are building and designing speakers from scratch and don't have a soundproof room etc.. I'll give you an idea of how they might sound:
I heard a low flying jet fly over our house and I went to the window near my speakers to see the jet. But it turned out that the jet sound was from the speakers a metre away! My friend was fumbling with his phone, try to stop it from beeping, and it turned out to be from my speakers, 3 metres away, while holding his phone. Being the only one in the room, I sometimes hear a "real" voice in my room and I get a fright. Turns out to be from my speakers. This happens with my open FR driver plus boxed woofer, as well. But I love the 10" open coaxials cos the voice sound has more oomph! The med range is more ROUND than with my FR driver versions but the coaxial is still just as open and AIRY! They are the best speakers I made so far at least.
My next project is the same, but with a lower, more squat up-side-down flower pot to allow room for an extra (open)10" woofer, for even better punchy bass. A boxed woofer with an open woofer on it, and the 10" coaxial driver on top (on a tripod frame around the bottom flower pot). 😂 You need the boxed woofer to give it the warmth. You might think it would sound cold and harsh, but not with the boxed woofer! You can balance the coldness and warmth, cos you can easily get either way, so it's just a matter of tweaking it. And of course a boxed woofer gives you real bass! 😂
@Worlds_Biggest...: I've build a number of sets of speakers and you are absolutely correct!
@philippeterson9512: I’d like to add my story on how to get the best speakers, or the best system. Back in my mid 20s(around 1992) I got into home theater, and wanted to buy a whole home theater system. I spent hours looking at magazines, visiting all the different retailers, etc. I agonized over every single decision. Eventually, I settled on a small speaker manufacturer near my house in New Jersey, I got the CD player from another place, and the receiver from another. The TV I chose was the one that was used to demonstrate DIRECTV, the first digital TV provider. Plus a VCR with VHS hi-fi. I didn’t have a big budget, but I had a lot of time on my hand and I really put effort into this. I loved that system, and I still use the speakers today in my workshop and they sound great. But over the years, my career progressed and I make a lot more money. So I upgraded my system. And although my system today blows away my first home theater set up, I never really get the sense of pride out of it that I did back then. I’m getting ready to upgrade once again, but this time I want to build my own speakers. My hobby is woodworking, so the cabinets are no problem. But the design and component selection is what I’m going to spend my time on. When I finally get these built, I know that when I fire up the system, I will get a warm glow inside.
@AudioMasterclass replies to @philippeterson9512: Maybe you'll build transmission lines and tell us all about them. They're the kind of speakers that need a proper woodworker's touch.
@philippeterson9512 replies to @philippeterson9512: @ 😁 if you can be my mentor on the design and picking the components, I’m game. I will warn you that my home theater room is very oddly shaped.
@rogersharpe2490: In the late 1960’s , I proudly owned a pair of the original Leak Sandwich speakers that were beautifully finished in teak enclosures. The company owner who if I remember correctly was Harold J. Leak bizarrely advertised these products by standing on top of one of the drivers cones to emphasise their stiffness I suppose ! What that had to do with the sound quality of his products is a rather debatable point. I do remember enjoying the ownership of the Leak speakers when my journey through hi fi and music generally was just beginning.
@AudioMasterclass replies to @rogersharpe2490: The point HJ was trying, seemingly unsuccessfully, is that the diaphragm of a woofer needs to be both light and stiff. Obviously the lighter it is, the more bendy it is likely to be, resulting in distortion. The heavier it is then the less efficient the driver. I don't have any evidence either way whether the sandwich principal was worthwhile, but it doesn't seem that other manufacturers have been in a rush to copy it.
@rogersharpe2490 replies to @rogersharpe2490: @ I don’t recall any other manufacturers following the sandwich principle developed by H J Leak. In those days some of the British speaker firms were using horn loading principles, particularly a company called Lowther Acoustics who enjoyed particular success with their PM6 which only required low powered amplification to drive them adequately.
@ninovasev: Hahah you always make me laugh... The spirit bmw haha
@MrHristoB: Totally agree. I've been building and experimenting with my own speakers, amps, equalisers since I was a teenager. Etching the PCBs myself using my mom's nail polish to cover the traces. Unwinding old transformers for the crossover wire...Ruined countless T shirts in the process. With electronics and woodworking always been my hobbies, it was some combination. You cant beat the satisfaction of building something yourself. What a time it was....
@jefferysmith5921: I build some speakers in Wood Shop decades ago... And, they sounded really bad! LOL
@MarkLloyd-yo4li: I can barely tie my own shoes let alone build a speaker, but i can train a horse. The best speaker in the world for me will be the one i like and love the best that i can buy 'not build '. 😂. Luckily I love my Focal 826D dual duty speakers. Focals entry speakers which happened to be on clearance to make way for the Thevas . 60% off 🎉. I paired them with 2 REL T9x's on sale $300 off each . Im over the moon . Merry Christmas everyone.
@Tonysia-y: my first build was 2 jam tins and some fishing line . . . .
@joecotter6803: The way to get the best speakers in the world is to read as many reviews as you can. Then buy the ones that the reviewers like for the styles of music you listen to. Never give the speakers a listen in the shop.
Then, never listen to music anywhere else that has hi-fi loudspeakers.
These will be better than any radio/pub or bar system. Never, ever set foot in a hi fi shop or go to a hi fi show. Ever.
@HappyUser-d1x: I built speakers in the 70's but in the 80s I was using four Wharfedale Diamonds in surround. My new Philips 2x60Watt HiFi came with two 3 way large speakers which sounded terrible. So I modified them. Using crossovers I could easily outperform my Diamonds with both the plastic and doped paper dome midrange. But peaked with a 3 way crossover which 30 years later I am still using. I have since improved with damping and super solid heavy metal stands. I replaced the failed 165mm woofers but no change there. I have a sub but only use for movies. I disagree that design is essential. I am an electronics expert; you can design for one frequency but not for a full range; otherwise top speakers would suffice with a single driver. Crap. Speaker design is a compromise. Great chat Mr Masterclass.
@Stratman6969: Absolutely right
@gino3286: Hi ! thank you very much for your excellent video tutorials I am stuck with the drivers selection and quite lost actually
The drivers are like raw materials in cooking Their quality set the level that can be reached When used rightly of course
I heard stories about cheap drivers sounding better than much more expensive ones
It is very difficult to assess their quality
A very excellent 2 ways speaker uses a woofer from India that could cost like a pizza and a beer This is my nightmare
Drivers selection
@rajendrabareto8065: The best thing in the world for me that what I have made out of my own hands and my mind😊

@bartbarelds8454: Allot of what i did, not sure my speakers are the best in the world but i have yet to a/b test them with a better speaker 😅
@vincentw9610: @AudioMasterclass is it really the best way to build your own speaker and amp to save money and get what makes you happy?
@nman2563: Do not follow this advice. Ask me how I know.. I have owned speakers from 0-thousands of dollars. I've built my own designs. I've built kits. I have a World Design kit waiting in the wings, designed by the legendary Peter Comeau. The problem with homemade or kit speakers are that you never know what you are going to get,. Most of my homemade speakers speakers did not please me even though they were technically fine. You do not have blinders big enough to look over speakers that do not fundamentally sound good to you. It's a money pit. I've recently bought a pair of speakers I love - a set from a Sony Midi system of 40 years vintage.
@jeremyaguilar3805: Fantastic video. I have built a pair, a trial pair of speakers from a kit. Very challenging since I have not soldered in 25 + years and I was not accustomed to reading electronic schematics. They speakers sound ok. I purchased the recommended book, I am sure I will build more, maybe without a kit.
@socksumi: You built Falcon Tabors from a kit? So did I in 1980. Mine used Audax woofers and tweeters in a ported box. They were very clean and deep in the bass but had an odd tonality... a leaness in the lower mids that made an alto sax sound like a tenor sax. I venture to say the crossover was the culprit. Often designers were not as good as they are sometimes made out to be.

@isaachunt5799: Get the room right then you have the best speaker. a multi million dollar speaker in a big echoey room will never sound any good. the room is everything imho. get the room right than you have it cracked
@jsprite123: If there are "loudspeakers", are there "softspeakers"?
@philippe7166: You can build speakers that will be very good speakers if you made active filter, good measurements
And this time it’s not just for you it’s available for everyone
Just forget passive filters and don’t forget to make good measurements
If you just put hp in a box like that it will be crap

@robertforrestmontreal7707: I build a set of speakers in the 60's warfdales they were ok Then i made a huge mistake I build a kit of goodman speakers It includes 1 woofer 1 horn midrange 1 horn tweeter 2 volume controls per side 4 total a bass port and instructions for the cabinet and crossover . I built to exactly what they said In the money of the time they cost a small fortune . To my ears the sound was garbage the horns sounded like listening in a bathroom the volume controls $20 each in 1962 money didn't help I swore never again to take a chance on speakers I can't hear first . Later bought AVID 103's which were excellent at the time and a good price now have B&W 100 i's with a polk subwoofer .

@bb_lz9790: A couple decades ago, I visited a friend's place of business. He led me to a room on the second floor that was filled with raw drivers. He told me that he bought out a jukebox manufacturer when they closed down. He said that he'd never get around to doing anything with most of the drivers and told me that I could help myself to what ever I wanted. I was not bashful and loaded up my car.
Knowing nothing about each driver, I borrowed some test equipment and proceeded to determine the Thiele-Small parameters that I needed to design some enclosures. A trip to the lumber yard ensued and I turned the stack of plywood into a bunch of bass reflex enclosures.
The largest set had two 15 in. woofers per side, a horn loaded 12 in. midrange and a couple horn tweeters. I designed and built the crossovers myself.
At low volumes, they didn't sound that good. When turned up to the point where my wife started to object, they actually sounded pretty good. In hindsight, I'm not sure if it was the loudness or perhaps she just didn't care for Joe Satriani's Surfing with the Alien CD!
I ended up selling off all of my creations. I didn't really miss them, but it was fun!
@bb_lz9790: That was the most fun I've had watching a YouTube video in a long time! Thanks for sharing!
@chowd.a.d.8309: Hi "Master". How on earth do I know what "crossovers" my DIY hifi speakers needs or should have?. Kindly if you could dedicate a stream on this topic. I'm in progress to build a pair of big speakers something like "Kappa 8", but better I hope. I'm searching for an open and detailed "wall of sound" that fills the whole room without having the volume at full blast. Listening mostly to guitar rock, jazz and blues. I think I have sufficient power amplifiers for heavy load, 2 pcs Primare A35 mono blocks 800W - 8 ohm. All the best.
@AudioMasterclass replies to @chowd.a.d.8309: For this I would recommend a loudspeaker building forum. You'll find more information on this very specialised topic than I can provide. https://www.google.com/search?q=loudspeaker+building+forum
@mannye: You forgot that to REALLY build the best speakers in the world you have to learn how to make the components yourself... just kidding.
@AudioMasterclass replies to @mannye: It wouldn't be impossible to make your own inductors. I'll bet some audiophiles do.
@mannye replies to @mannye: @AudioMasterclass I wasn't trolling... just illustrating the rabbit hole we can go down. Frankly, had I thought this was possible when I was a youngster, I might have given it a shot.
@AudioMasterclass replies to @mannye: @mannye Neither was I. It wouldn't surprise me at all if a subset of audiophiles improve their speakers with hand-coiled inductors.
@mannye: I disagree. The best speakers in the world are the ones you like best. And yes, you will want to build yours. BUT you will not build the best speakers in the world until AFTER you build the worst speakers. in the world.
@stavroskarnezis843: During the 90s, I studied at the University La Sapienza in Rome. One of my favorite pastimes was visiting Cherubini, which was considered one of the best Hi-Fi stores in Italy at the time. They had multiple locations, with one close to me, but my preferred store was in a region called Ottaviano. This particular store had a spacious showroom where customers could explore and listen to a wide selection of high-end audio equipment combinations.
I vividly remember one day when I was browsing around and suddenly became captivated by a symphonic orchestra piece emanating from the big room. The salesperson, whom I was familiar with due to my frequent visits, politely invited me to sit on a couch placed directly in front of the speakers that were playing at the moment. As I settled in, the room seemed to transform into a theater, and it felt as though the symphonic orchestra was performing just for me. It was an astonishing experience, and I was completely enthralled. Eventually, the music piece concluded, and I had to leave the room to allow others to enjoy the experience. Before departing, I inquired about the equipment combination responsible for such a magnificent result. To the best of my recollection, the source was a CD player from Nakamichi connected to a pre-amp of the same brand, two Threshold monoblock amplifiers, and a pair of Klipschorn Speakers.
After this remarkable listening experience, I was left with a bittersweet memory, knowing that I would never be able to replicate that performance in my modest listening room. Since then, I have been enjoying my favorite music on a Luxman LV103u with a pair of Infinity clone loudspeakers. To conclude, I highly doubt I can build anything even remotely close to that....
@MrFrobbo: This vid is a trip down memory lane and echos thoughts around a recent update to my xover, thanks, great channel.
30 years ago I embarked on a ground up design and build of my 2-way Scan Speak front ported 'book shelf' (large, on stands) and I was exceptionally lucky to have a local audiophile business and well regarded speaker designer and manufacturer near by, and as an apprentice took a chance to pop in for some advice. I was greeted with an exceptionally kind reception (from the owner of the well known family business) and he gave me many pointers including the scan speak 18w 8545 and advice surrounding the build and selected tweeter the Scan Speak Revelator 2900 including how tricky this match would be. However I forged ahead using the same book you mention and they were indeed 'the best speakers in the world'. But I was never that impressed with the crossover and stereo separation, I even designed and custom produced the inductors myself.
So fast forward to last month (30 years later) and I decided to revamp the xover using modern equipment including simulators (Vituix) and a calibrated measuring mic with REW, and BOOOM, I've never been so pleased, even though I did buy the xover parts this time, infact the coils were actually better than my attempt.
I could not only simulate xover designs, I could measure them, phase, SPL, time delay!
I now have even better 'best speakers in the world' and I'm exceptionally proud, which is obviously why they are the best, it's all psychology and effort, and that's great.
I could also hear the wandering clarinet 😉👌😎
@jwestrik9308: It would be a Sound investment..
@Snowsea-gs4wu: Wonderful story, thank you!
@3limin4torZockt: Hey i came back to your video to say your right.
I own a the PMC Twenty5 26i, they cost 11'000&.
So i thougt you just havent heard this quality thats why you say you can build better ones.
But now i started to build my own speakers and i have to admit, he is 100% right!
Ive never heard something sounding sooooo gooood!!
I will sell my PMC's!
I thank you so much! ❤☺️
@mikey92362: I built my forst pair of speakers when i was 13 years old.
I got hired to clean out a warehouse for the local Datsun/Nissan dealership.
They said i could keep anything I found.
There were 40 pairs of brand new Nissan factory car speakers. About 2/3 were 6" and a thirrd were 4". All were just single cone, full range drivers.
I bought four sheets of plywood and made two huge boxes. Took an entire day to cut out 80 holes!
I learned about ohms and even bought two cheap crossovers to separate the 6" from the 4".
Tool a while day to solder so much wire!
And in the end, the result was totally worth it! They sounded absolutely terrible. Probably the worst speakers ever made.
But they were big and allowed me to start a DJ business that eventually paid for college.
And they made me save my money as fast as possible to buy better gear!
I sold those speakers to a middle aged stoner named Biff after about a year and he loved them. LOL
@joedeegan3870: EMI Model 62 speakers are the best I have heard in my 79 years an they were only 80 dollars new each:
@knutarneaakra6013: Best? No but at the time it was great.
@fonkenful: I’ve owned my fair share of “audiophile approved” speakers over a period of 40 years, then stumbled into the rabbit hole of DIY building - and damn, but you’re right: every single pair of the hundreds* of those was the best in the world - until the next.
*not an infinite number, but more than I can remember.😂
@petermach8635: My first speakers were a pair of Acoustic Research ones, bought in 1975 using a Thorens turntable and a Cambridge P50 amplifier, after that a pair of Spendor SP1's with a Quad 33 and 303, then I had a week working at Linn's factory outside Glasgow where I had a demo of their then new Kan's and as soon as I got home I bought a pair of those, only I could never drive them hard enough living in a London flat to make them sound as good as in the demo room. I very quickly traded them in for a pair of Harbeth LS3/5A's which suited me perfectly until I fell for a pair of Quad 7710's which, 35 years later, are still standing on the old Kan stands in my sitting room ... I might not have built them myself, but to me they're definitely the best speakers in the world.
@LordVictorHalgaard: This definitely hasn't been true for me, I'm just as critical of my own work, if not more so, than any store bought speaker.
@AudioMasterclass replies to @LordVictorHalgaard: The people who are the very best at what they do are never happy with their performance, which is why they are the best.
@Freedom89984: Don’t think you can do better than KEF. Just buy a pair of KEF LS50 meta. €1000 and you’ll be happy. I’ve build some speaker sets with the best Scan Speak and Vifa drivers. But you never get the balanced sound of a good production speaker set.
@blackdaan replies to @Freedom89984: scanspeak make drivers of 200 600 1000 2000 and 6000 each. what you used?
@3limin4torZockt replies to @Freedom89984: Uhm my Markaudio Speaker (Selfbuild) wich cost's 300 Dollars outperforms my Dali Epicon 2, Canton Karat Reference 2DC, PMC Twenty 26i, Magnat 703. I thougt the same thing, especially with my PMC Twenty 26i wich cost me 11'000 Dollars new. So yes you can get easly get the sound of a good production speaker set, id say.. :)
@thomasschafer7268: Vor 30 Jahren konnte man sich die diy Bausätze vorher in Shops anhören. Erst dann gekauft. Das waren noch Zeiten. Schraubt man heute fertiglautsprecher auf bekommt man Tränen in die Augen. Was ein Schrott an billigsten Bauteilen.
@MammaDuckk: I tried to build a pair of speakers once, and they sucked. I gave up after that.
One thing I've found is that speakers never sound like being at a classical concert or an acoustical jazz concert. I wanted speakers to sound like being at the concert sounded, but I've never found that. I'm thinking I should become ungodly wealthy and have my own chamber historically informed chamber orchestra. The problem is, I'm not close to being that wealthy, and since I'm retired, I won't be getting any wealthier. Therefore, I'll probably just stick with what I've had for the last 40 years. I'm also not handy, so self building is probably not going to help.
@blackdaan replies to @MammaDuckk: what you builded than.. i am about the buy the audimax reference kit. its expensive.. but ive heard it should beat 20 30 40k speakers
@tigertiger1699: I might build a birdbath😂👍
@tigertiger1699: Interesting…, as an ex Fitter Turner…, I wouldn’t bother.., it would take considerable effort n practice to make anything as good as my Dynaudio Contours…, a lot o time..
@OriginalWis: You are wrong sir. Very wrong. The correct answer is no, you cannot have the best loudspeaker in the world because Hollywood let Marty McFly destroy with one (albeit legendary) guitar riff 5 minutes into the movie. Thank you Marty. Because of you and Bif, we can no longer have nice things. 🤬
@AudioMasterclass replies to @OriginalWis: Classic.
@luisdiaz3887: I’m too old to start building anything, anyway will you consider to give me and advise about how to keep in shape my KEF 104.2 please if you don’t mind lad. Regards
@AudioMasterclass replies to @luisdiaz3887: That would be out of my range of experience but there are forums on the web on speaker maintenance so a Google search might strike lucky.
@garywells9478: My first speakers had twin eight inch co-axial drivers. They weren't good. Then I built a pair of speakers using Isophonic drivers from a junked Telefunken console stereo. They sounded amazing. A while later, I acquired a pair of Altec-Lansing 515's and built a pair of A 7 bass horns. I added a subwoofer, which I built using two JBL fifteen inch drivers. I own the best speaker system in the world, or so I think.
@TriAmpMyFi replies to @garywells9478: . Same build type here. Copied (without plans) the JBL 4560 horn loaded bass cabinets. Couldn't afford the JBL drivers so I chose the Electro-Voice 15's. Horns were all Peavey in Peavey cabinets.
No crossover, full-range signal to both. Peavey had internal protection & attenuator.
I was a working pro-dj & those speakers kicked ass compared to almost anything then.
Acid Jazz, Funk & Brass 🔈🔉🔊
@sjors01: 👍🎷🎷
@ccdccd8615: Love the tongue in cheek presentation in this video. I have gone this road before and suggest a 4th path. Pretend like you are going to build your own speakers from the ground up and, at the end of the day, DON’T DO IT! There is a reason for this madness and it is simply that trying to design your own speakers teaches you about the various aspects of speaker design. This comes in handy whether you buy an off the shelf speaker or a kit.
For example, I am a fan of open baffle (OB) speakers. Cabinet design is relatively simple because you are mounting your drivers on a single panel and I love the OB sound. However, OB speakers need to be around 3’ from the front wall. It is also hard to get deep bass out of these designs unless you are using large drivers mounted on a large panel. There are ways to reduce the size of the speaker, and that basically comes down to a hybrid design where the tweeter and mid-woofer are in an open baffle and the woofer is not. There are generally 3 choices (sealed, ported or passive radiator). My preference would be passive radiator as (to me) it offers the best compromise of sound quality , reasonable size and bass extension. I would also tend to prefer bi-amped 3-way speakers where only the woofer is powered because you generally need a fair amount of power to get the most from woofers, Class D amps work well in the bass region and are cheap, and finally, powering the woofers allows you to use much lowered powered amps for the tweeter and mid-woofer.
All of this came from researching speaker design. Part of building the best speakers in the world is knowing what you want and the considerations in the best design to accomplish it. This knowledge allows you to make better choices whether you buy or build your speaker and informs you of what you should be looking for because you know the compromises in a particular type of design.
@asterixx6878: You joke about it and quite grossly underestimate us DIYers. The fact is, however, that many have (at least) as much knowledge as the 'professionals'. Let put it like this.....
For 600-700 Euros, you can easily build speakers that are at least as good as factory-built speakers that cost around 3000 Euros.
If you don't want/can't build the speakers yourself, there are many sites that provide full build descriptions (Audioexcite, Troels Gravesen, Zaph Audio, etc.)
And yes, I have designed my speakers myself. Cost is around 700-800 Euro. Are they better than ready-made speakers in the 3000 Euro price range? I haven't listened to all the speakers in this price range, but they easily beat all the ones I've listened to.
