For those interested, this process is the called Translam construction method. Manly used for small speakers. The snaking chamber behind the speaker driver is used to amplify the bass. The drivers are Audio Nirvana "Super 8".
@@misterhat5823 It does have a expansion/flare rate so technically it is a horn. Wasteful perhaps, but you can machine an accurate expansion profile in one plane.
A very nice video, thank you! Nice transmission-line / horn design around a good full range driver. Likely very suited for small to medium rooms typical in Japan.
This looks like the first attempt by a furniture maker to use his CNC machine for speaker building. I'm not really sure what to think of the sound absorbing material either. Coffee filters glued to the wall? The guy building the speakers seems to be having fun though. That's very important in life.
They have a decent process, with plenty of room for improvement. Note: 13:55 -- he seems to be leaning over, manually screwing the speakers in place, while the cabinet is sitting on a chair or push cart, at knee level. That's fine, if you make 4 speakers per day... but it'll never work, for high production. I'm sure they simply have no need of Kaizen, at whatever scale they operate on. It's hard to comment on, without context. I could question a dozen production choices, but for all I know, these could be the best speakers in the world. I can't complain, without hearing them, in person.
Mi papa construia parlantes de ese tipo TL con drivers que compraba en USA y los traia a mi pais, usaba programas de calculo de cubicacion y todo, los terminaba escuchaba unas semanas y los vendia por Mercadolibre a precio muy barato, era su hobby, nunca entendi el proceso y lo complejo que era, solo pensaba que era una caja de parlante no mas, viejito donde quiera que estes te envio un abrazo y sepas que te amo, fuiste un incomprendido con estas cosas y te trataban de loco🙏
👏🎶🇵🇱 I'm impressed, you're my Master! Your skills and dedication are truly admirable. It's amazing to see the production process of wooden speakers for jazz music, and the outstanding factory in Japan where it all happens. Your craftsmanship is exceptional! Greetings from Poland! 👏🎶🇵🇱
Entrei no site da empresa e vi outros produtos que eles fabricam. Tem umas caixas de som com tampa de vidro e amplificador no centro , que coisa linda !
As far as I know, most technology comes from the west, only a few technologies come from Japan. But somehow, I'm so obsessed with Japanese brands. If you talk about quality, you have to talk about Japan.
Je plussoie; à noter toute la rigueur, la patience, et l’attention portée au travail durant toutes les étapes de fabrication; avec les japonais, le mot détails n’est absolument pas un mot comme les autres…
Very relaxing to watch them building a speaker, I feel it's a family run business 👍 all the care that goes into making the speakers very solid construction ❤👍👏
Some serious investment there from the vertical panel saw to the multi head cnc. I didn’t see much in the way if dust extraction yet it must gave been present as the workshop was pretty dust free! Not s fan of full range whizzer cone drivers which always sound coloured to me but liked the transmission line construction of the cabinets. They make in a day what it takes me several weeks doing by hand full time working using hand build techniques for custom speaker designs. Surprised not to see flush mounting of speaker driver and no gasket used? No linearising filter ? Must be a pretty well behaved driver!
This is absolutely the coolest thing ever! Has anybody heard these speakers? Even the speaker connectors were isolated by two slats of wood that is incredible!
Yes. Single driver backloaded horns/TLs are a known design, made popular by Fostex of Japan I think. They sound good, depending on how good the driver is. Making them from layers of mdf this way is also known, to DIYers and manufacturers.
Los japoneses son seres especiales. Nos hicieron dar un gran salto tecnológico especialmente en el audio en la segunda mitad del siglo XX. Su innovación y su perfeccionismo llevaron el sonido a otro nivel.
Чего добивается автор? Автор просто делает хорошую акустику. Понять хорошую акустику дано не каждому. Если ты слушаешь речи путина, цыганову или киркорова, то тебе хватит и компьютерных колонок. Ну а если ты хочешь понять акустику то для начала послушай записи Листа, Бетховена или Баха с винила, а потом уже думай
Very inspiring to see this production process. What made me wonder is at the end, when mounting the driver with the flat iron on the housing, with these carved vertical lines on the baffle and the driver just mounted on top of it, this speaker will not be air tight, there will be leaking air through these carved lines. That's quite a curiosity. Another curiosity are these paper-pillows inserted for damping, reminding me some people claiming that bubble-wrap inside on the speaker-walls would provide a formidable damping. The heavy machinery looks expensive.
there are indeed several little anomalies in the design and assembly process that may not reflect ideal best standards, and even the choice of placement during listening, however the old dude seems to love the end result
The entire concept is pathetically wrong headed and incompetent, right down to the packaging. Inexperienced audiophiles will be impressed, though, and will part with too much money to have them in their possession. I’ll bet they sound ridiculous - so many fundamental acoustic principles are violated in this silly design, it’s really not worth detailing them.
@@russelldawkins9094 BLH/TL, back loaded horn/transmission line hybrids, can produce extremely good results in relatively small cabinets. Here's a quote from Martin J King: "If done correctly, a hybrid transmission line / back loaded horn enclosure will not require any baffle step correction circuit which is the real big advantage. Imagine 94 to 98 dB SPL, at a 1 m distance for 1 watt of input, over the frequency range 50 Hz to 15-20 kHz produced by a single driver enclosure that is slightly bigger then a commercial tower speaker system. No crossover, no correction circuit, just a speaker cable running directly from the amplifier to the driver. Based on the work presented in this Section, I am convinced that this is possible and even predictable from the MathCad worksheets." Best to listen before passing judgment...
I'm done with ported enclosure. I'm now into sealed enclosure, more accurate and more natural sounding than ported rivals. And more economical and simple to build. 👍😊
They're not ported nor are they a transmission line. They also have a whizzer cone full range driver. There is so much wrong I don't know where to begin. However, if they can sell them, great.
Donde puedo aprender a hacer estas cajas, por donde deberé empezar , tengo maquinaria de corte, y me gustaría desempeñarme en algo así, pero lo siento complejo pero me llama mi atención, alguna sugerencia?
I think it's a great shame that you didn't include the final finishing touches to the surface, would have liked to see what they used to coat the black colored one
Well that is a very nice and quality job...yet I would have like to have seen more of the steps taken after the speaker was installed to the finishing. How the grooves were made and how the different finishes were applied.
Japs make good sh!t 👍 I'm rocking a set of Radio Shack circ. 1982ish Minimus 7's still sounding as good as I can remember back in the day. I have Alpine Car Audio, Fuji Camera, along with Olfa Knives, Shimano Bicycle Parts on my Nishiki Sugino on my Fixed Gear, I use Makita Drills and Impacts at work, However, I do not drive Japanese Cars.... I drive Domestic 😃 Chevrolet and GM products.
Speaker terminal post should be tightened to the case with one nut and the cable should be captured between that first nut and a second nut 6:02 or it may come loose with changes in humidity and materials expansion and contracting
There is so much mistakes in this whole video that I'm not going to even try to explain them all. And yes I'm carpenter and cnc machinist and made lots of furnitures, speakers, drums, other instruments etc, and this video hurts my soul so much. I'm amazed that Japanese peoples can make so much wrong in one video, usually they do pretty good work.
J'ai fabriqué deux enceintes comme celle ci lorsque j'étais plus jeune, cela s'appelle le processus d'amortissement Infini. Les basses descendent en fréquence tout au long du cornet qui est de plus en plus évasé. J'avais ajouté un U mobile qui permettait d'accorder les harmoniques sortants.👍bravo pour la qualité et le design de la fabrication. Il est vrai que la machine permet une grande régularité de découpe!
como eu gostaria de poder ter um par de alto falantes assim. aqui no brasil eu fico vendo esses videos e tento fazer as minhas próprias caixas acústicas. hoje tenho duas linha de transmissão com alto falantes de 15 polegadas e outras duas caixas com 3 vias de boa qualidade. um dia espero poder conhecer a cidade onde vocês moram. Parabéns pelo trabalho de artesão.
@@antonkovalev6259 а, понял. Там покраска не простая. Первый изолирующий слой, второй грунт, краска и, возможно, лак. Если бы они не спрятали провода в корпусе, то они были бы чёрные, в цвет кабинета. Но они имеют свой цвет, так что лаком там и не пахло.
I can't imagine how much one of those speakers weighs, never mind how much it costs. Also, I really wish they'd shown how they get all the sawdust out of that enclosed, folded horn.
