Beautiful build, may I suggest adding a very thin lining (0.25cm) of your choice of sound absorbent in your next build to the insides. Yeah I know it is anathema for this design but you could try it out.

[@emmnuelj6136]

Hard wood he is using will do the damping job due to its density

[@Goonaroi]

Transmission line speakers have been around for 50 years or more. They always have sound absorbency fabric. The timber cabinet can vibrate and create unwanted harmonics from the higher frequencies (500khz+) you don’t want. Place your hand on your speaker cabinet, if you can feel vibration put your ear on the cabinet and listen to the muffled ‘timber speaker’ adding to the sound of the cone speaker at the front.

[@jp-um2fr]

Around 30 years ago I studied many old 1940's / 1970's books on folded horns, Helmholtz resonators, etc.. I have two 15 Ohm 15" Tannoy monitors (folded suspension) and the cabinets are just a bit bigger. Takes 3 to lift them. Even now after all those years I would not change anything. What's was good enough for the BBC is good enough for me. Lovely to see someone taking pride in what they do. I am a little surprised there is no sound absorption anywhere but if it sounds right - it is right. Ask in a shop these days what the resonant frequency or the dB / Watt of a speaker is and they look at you as if you come from the planet Zod. My advice to anyone regardless of budget is do your homework , there is an awful lot of expensive crap out there. These little speakers on the video do look good, perhaps some soft feet? Being picky.

Beautiful cabinetry. Needs a tweeter and also loose sound-absorbing insulation in the rear transmission line to reduce mid and high frequencies which arrive at the rear port out of phase with the front speaker.

[@Goonaroi]

The bass speaker would have a top range of 12khz which is below the 16khz minimum needed for high fidelity. The world famous Rogers LS35A BBC monitor uses a similar woofer with a KEF T27 tweeter. The bottom range of the T27 overlaps the top range of the woofer giving a balanced sound. Adding sound absorbency material to the transmission line reduces and absorbs unwanted frequencies radiated from the rear of the cone without affecting the frequencies you do want. The transmission line is designed to reinforce low frequencies lacking in the small bass driver. That is from about 200hz and below. Everything above 200 hz only deminishes the clarity of the sound.

Nice work! I like the tunes too! Great job

[@richysee]

Your transmission line system is brilliant and produces amazing low frequency response but the midrange appears to be colored by cavity resonance within the unlined\unfilled enclosure. This can easily be remedied by stuffing the enclosure with polyester wool available for the purpose. Trial and error stuffing density will yield the desired tonal qualities. I built my own 12 inch 3 way Onkyo transmission line system using much the same principle of 1/4 wave cavity resonance to enhance the bass.

[@juststuff5216]

Hands up, through all the years I've been designing t-line, I've never designed one of these types of enclosure.

As someone that owns fe206 fullrange in back loaded horn loosing a little high is well wort it, Voices and imaging are just amazing and instruments sound real. Unfortunately as soon as you add a second speaker you have phasing problems as both driver will be a different distance from you, unless your head remains in a vice.If you ever get a chance to listen to some they will sound a little thin at first as the cabinets dont fill in the sound very much, but if you iove voices and the sound of real instruments , although no perfect you wont look back, promise.

Few comments. Driver is HiVi B3N 3" Aluminum Driver from Parts Express, only 10US$. So quite impressive for the price. Nevertheless, despite all the efforts, without any internal padding the result is not optimal. Further, there is a perception of bass but this approach without a subwoofer is destined to a limited appreciation of music with low end. 価格の点で非常に印象的です。それにもかかわらず、すべての努力にもかかわらず、内部パディングなしでは結果は最適ではありません。さらに、低音の認識がありますが、サブウーファーを使用しないこのアプローチは、低音の音楽を限定的に鑑賞することを目的としています。 I just built a TL design using Tang Band 5" with similar results. Even with some eq (raising 32 - 64, dipping 1k - 2k), thinking of adding a sub to complement. Glue is Tirebond, easily available. As for Aron Alpha products, not sure we can find the exact match in the US. After someone asked Mr. Syujiro, he explained: "Thank you for your comments. Aron Alpha wood glue and its curing spray. Instant adhesives are relatively resistant to misalignment, but are vulnerable to shocks, so they are used to connect the time until the tight bond is cured." From there, it could be some form of cyanoacrylate (Krazy glue) with an accelerator spray, which works in tandem with the cyanoacrylate, seems available only in Japan, but Tirebond has wood adhesives and accelerators as well. Adds to the cost but saves time. Thank you for sharing, excellent wood working. 共有してくれてありがとう、素晴らしい木材加工。

what's the theory behind the design? Seems very silly and couldn't work well. that port is gigantic!!! please do a video with measurements, if you have any.

Internal geometry like that is in order to reduce standing waves, and in theory reduces distortion and peaks. By introducing a "random" path sound waves reflect and interact in a random manner. It's well studied, typically it's mostly a matter of insuring there are no internal parallel faces (external can also matter).

Looks like it might be a folded tapered quarter wave tube

@@whirled_peas My confusion with the design is that the one half leads to a dead end and the other half leads to a vent that is larger than the woofer. It isn't a t-line; it's not bandpass; and I don't see how it could work well.

@@TheMarried123 I looked at images of "acoustic labyrinth" designs. the air in those types of designs go in and out through a winding port which vents outside of the enclosure. the design in this video has a "labyrinth" leading to a dead end, not outside the enclosure.

狭窄管で反響させて出口から低音を出すって考えなのかな？
