If somebody is making a loudspeaker for the first time and they don't work 100% , rip em apart and tinker with the design. The finale cosmetic covering will hide the attempts and versions...
A few things come to mind. 1. The Xmax of that speaker is likely not sufficient to handle the wavelength desired by such a port. 2. There will be all sorts of unusual resonant frequencies heard with this un-reinforced construction method: tubes, ports, cabinet. 3. The enclosure and the desired port tuning frequency do not appear to be well matched. 4. The port length and diameter do not appear to be well matched. 4. There are bound to be phase issues, here.
I wonder what the theory is? Why do you need such a long duct? After all, we all know how the tube distorts any sound. If the emphasis is on amplifying low frequencies due to resonance in the pipe, then I would like to see a method for calculating the diameter of the pipe, its length and the number of elbows, which are highly undesirable in acoustics. Otherwise, there will be no amplification compared to a conventional phase inverter, but we will only get a distorted, colored sound that is very far from the sound engineer's idea.
Similarly, I was wondering if you calculated the overall length of the ducts, to make sure that their output is perfectly in phase with the output of the woofer.
I think after a certain amount of tube the gains are diminished. We use to build subwoofer boxes,use different diameter and length of pipe to tune the boxes.
I believe you would need a crossover for the speaker to only drive the lower frequencies for it to actually be a dedicated subwoofer. Even then you still need a woofer (speaker) that is rated down to 20hz or at least down to 50hz for it to be classed as a subwoofer.
I remember putting my cassette player (I know, I'm old) into an empty dresser and opening the drawers. this was in 1970 something and the sound was amazing.

I guess the theory is the PVC Tubes funnel the Bass, but the length distance the air travels causes a delay better Bass. In the 80's instead of baffles or tubes, I used two or four woofers in a car in 1982. Never made a box square but they had a few angles if not rounded backs so the bass does not just bounce against a flat area never sounded as good. Woofers that required a large box to perform correctly, I reverse the polarity some how worked great.

remove the fittings pipes, &all then give 4 inch one pipe length 20 cm locate just bottom of near same woofer ( not back I mean front ), put glass wool inside box all sorround so you Will get more deep smooth bass 🙏
Did you mean, to use only ONE 4" pipe, 20cm long and on the front, lower part of the box? Does it matter the size of the box, as dimensions of this project were not given?
Now attach the speaker to the pipe to protect the speaker fully and fill the box around the pipe with cement/concrete/epoxy resin slowly to prevent any air bubbles and to make the pipe as RIGID as possible so that it prevents vibrations that causes the pipe to rattle over a period of time

Pulled the words right out of my mouth. Hoewever, simple sand will do. Finally, just using a long tube "waveforming" is not enough. The tube has to be tuned, if not, you get lower but smeared bass. Also, the ports need to be tapered, if not, it will also "chuff". Its easier to simply make a bass reflex enclosure, the bigger the box, the lower the bass. You can also add a passive radiator for additional extension.
the vent should be on the front... the box is huge you can put the mid and high range as well, insides of the box should have the sound absorber too you can use carpet or foam material. The effort is brilliant....

Have you never heard of pvc glue? Hot melt in not going to stand up to the vibration of a subwoofer. As far as shaping the porting of the speaker, it could have been achieved with wood panels that would have strengthened the cabinet and taken less time. And where is your baffling to stop those large panels from resonating? Sorry dude, but you have a lot to learn about speaker design.
The bass is equivalent to that of a semi-open box in which the front sound waves stand out. Rear waves are attenuated by the ultra long ducts (acting as a very low pass filter), so not cancelling frontal ones. This is why most of the sound energy is delivered frontally and centered around the high bass (40 - 60 Hz), close to the natural resonance frequency of the speaker. In this frequency range the box behaves close to a big closed box. The ducts aimed at very deep bass (lower than 30Hz) have no main function in this system, neither the speaker is able to deliver it. All this is a waste of time and plumbing, in my view. And lack of knowledge of minimal speaker building principles either. I will not leave a like which is of course the main aim of this misleading video.

It is far less expensive to simply buy two drivers, put them in an appropriately sized sealed box and equalize the bass response. You get a bass response that rolls off less than this design does below the port resonance and you get accurate bass with low group delay that a ported design can never have. Modern accurate hifi speaker designs don't use ports, open transmission lines or passive radiators.
Yes that is the downside with all pipes/ports. Everyone is used to that sound quality degradation when it is the norm when most of the speakers due to space constraints and the wish of having something small that should sound bigger.. If we on the other side want no compromise and with sound quality. Then skip the ported enclosure go with open baffle and big driver!
Such type of speakers were made by Sonodyne Company but instead of plastic pipes they filled the box with coir and thermocol and cotswool and the output was astounding.
That's an enthusiastic build. The extremely long ports will create excessive planar drag. Group delay will be high. Get a copy of some good software and speak with someone who understands it. If you can model port velocity, mutual coupling, group delay & other easily overlooked parameters, your results will improve dramatically.
There's a reason that deeply tuned sub boxes are big. The tuning on this is no doubt low, but at any volume, the ports will be noisy, and because of the multiple non-smooth curves, they won't be very effective... But hey, it looks cool.
I hope you put some damping material around the tubing !!, it'll stop rattling and sonic vibration !, also the woofer is going to work into the enclosure before the sound wave exits through the labyrinth tubes ?, or are you going to add a compression chamber between the woofer and the beginning of the labyrinth tube? Good video, though
I feel like you would want to separate the tube chamber from the speaker because the vibration would be on the outside of the tube and the inside therefore canceling out resonance.
Я все понимаю, если трубы правильно рассчитаны, то басы будут хорошие. Но, не на термосоплях же их соединять! Через час работы все развалится. Не серьезно.
My observation is that the woofer at the back hole centered perfectly to the magnet of the woofer with pipe that's very heavy bass but the video is also great
What is that subwoofer tuned to? I ask because it looks like quite long ports for a box that big, although in a small box you end up needing a really long port just to get a low tuning with adequate port area, which is why many use passive radiators. I've made boxes for 6 x 9 speakers and with 1.1 to 1.2 cubic feet each and 2 2.5" ports I think that were about 8 inches long, the tuning came out around 50 Hz which was low enough for a bass and mid woofer like a 6 x 9. I've also accidentally tuned a big PA speaker to 11 Hz when messing around with ports I had no idea of Helmholtz frequency calculations for (which means it wasn't providing significant boost in the useable range).
@@jasonmelo1974 in this big a box, you don't need that long a port to get low, especially if it's not particularly wide. The "11 Hz" PA speaker was an H//H Pro 150. I added a piece of cardboard pallet wrap tube to the hole where the bullet tweeter was. Later I entered the paramaters in Hornresp, given the box was just over 100 litres (4 cubic feet). This enclosure will function as a large sealed box, although maybe in the single digits there might be some boost, although the displacement of this driver is likely not enough to take advantage of it. You'd get better SPL just tuning to 40 Hz. Edit: I just did the calculations for 4 cubic foot box with a 4" wide pipe 12" long and it comes to between 24 and 25 Hz in half space. Still too low though for the type of speaker I wanted, which was a party/PA speaker for maximum punch above 50 Hz. Quadrupling or maybe 5 or 6 x port area would have got me there.
Bose use to make a speaker like that in like the 80s or 90s. In the commercial they’d cut the speaker in half to show the same tube like structure inside. I’ve always wanted to make one.
mendingan pake dekat Dari kayu aja... mungkin jangka pendek sangat bagus tapi Kalo jangka panjang suatu saat pipa Akan buat getaran Yang mengganggu.. tapi overall mantap Dan mampir ya
Nice job construction, but you should invest a bit more into the quality of the woofer and definitely add a Tweeter with the crossover and put more thick cables plus the finiture design outside then you good to go...
seems like its closer to a t-line concept than anything else. i was kicking around a similar idea but instead using 6 inch pvc pipe and fit a 6 inch sub in the end and run about 8 feet of the pipe. im pretty sure that if you have the ports firing the same direction as the sub yours will sound much better than it currently does. as it stands you have opposing waves cancelling each other out.
My thoughts on this: I do not own a CNC. I would use real wood. I would add material inside the box to minimise dead air space. Finally, I would buy speakers from some company that saves me all the work. My Image 200 speakers from the mid 1980s have excellent bass. Have fun to all the DIY guys out there.

Молодец мужик!
Olá. O profissional em epígrafe deveria trabalhar com COMPENSADO, no lugar desse papelão, chamado MDF. A acústica ficaria muito mais substancial.
все через это прошли, а сейчас всё до звезды!
the phase inverter output must be in front, otherwise it will dampen the bass in antiphase with the speaker
в данном чюде, это без разницы😆😂😂😆😂чисто столярно-канализационное видео...
just a waste of materials... no sense video...
The bass is equivalent to that of a semi-open box in which the front sound waves stand out. Rear waves are attenuated by the ultra long ducts (acting as a very low pass filter), so not cancelling frontal ones. This is why most of the sound energy is delivered frontally and centered around the high bass (40 - 60 Hz), close to the natural resonance frequency of the speaker. In this frequency range the box behaves close to a big closed box. The ducts aimed at very deep bass (lower than 30Hz) have no main function in this system, neither the speaker is able to deliver it. All this is a waste of time and plumbing, in my view. And lack of knowledge of minimal speaker building principles either. I will not leave a like which is of course the main aim of this misleading video.

Turning the port around would put the throat far from the sub and place the mouth on the front,,that's a win,win
It is far less expensive to simply buy two drivers, put them in an appropriately sized sealed box and equalize the bass response. You get a bass response that rolls off less than this design does below the port resonance and you get accurate bass with low group delay that a ported design can never have. Modern accurate hifi speaker designs don't use ports, open transmission lines or passive radiators.
PVCを使えば、より簡単につくれそうですね！
the downside of such a long bass pipe is that the sound out of the pipe is delayed in relation to the sound out of the bass speaker
Yes that is the downside with all pipes/ports. Everyone is used to that sound quality degradation when it is the norm when most of the speakers due to space constraints and the wish of having something small that should sound bigger..
If we on the other side want no compromise and with sound quality. Then skip the ported enclosure go with open baffle and big driver!
Watching here idol sending my love and support
Such type of speakers were made by Sonodyne Company but instead of plastic pipes they filled the box with coir and thermocol and cotswool and the output was astounding.
That's an enthusiastic build.
The extremely long ports will create excessive planar drag. Group delay will be high.
Get a copy of some good software and speak with someone who understands it. If you can model port velocity, mutual coupling, group delay & other easily overlooked parameters, your results will improve dramatically.
There's a reason that deeply tuned sub boxes are big. The tuning on this is no doubt low, but at any volume, the ports will be noisy, and because of the multiple non-smooth curves, they won't be very effective... But hey, it looks cool.
I hope you put some damping material around the tubing !!, it'll stop rattling and sonic vibration !, also the woofer is going to work into the enclosure before the sound wave exits through the labyrinth tubes ?, or are you going to add a compression chamber between the woofer and the beginning of the labyrinth tube? Good video, though
I feel like you would want to separate the tube chamber from the speaker because the vibration would be on the outside of the tube and the inside therefore canceling out resonance.
Good job bro..👍👍
Wouldn't pvc glue make this project a lot easier?
Отлить захотелось сразу.
I had a set of tuned speakers. they use an o-scope , generate a tone , adjust the tube length until the tone is just right.
Я все понимаю, если трубы правильно рассчитаны, то басы будут хорошие. Но, не на термосоплях же их соединять! Через час работы все развалится. Не серьезно.

My observation is that the woofer at the back hole centered perfectly to the magnet of the woofer with pipe that's very heavy bass but the video is also great
Valeu irmão ficou top e já apreendi parabéns
Well, nice box. As for the sound quality it's exactly as it should sound out of a sewage pipe.
What is that subwoofer tuned to? I ask because it looks like quite long ports for a box that big, although in a small box you end up needing a really long port just to get a low tuning with adequate port area, which is why many use passive radiators. I've made boxes for 6 x 9 speakers and with 1.1 to 1.2 cubic feet each and 2 2.5" ports I think that were about 8 inches long, the tuning came out around 50 Hz which was low enough for a bass and mid woofer like a 6 x 9. I've also accidentally tuned a big PA speaker to 11 Hz when messing around with ports I had no idea of Helmholtz frequency calculations for (which means it wasn't providing significant boost in the useable range).
With a port that long I assume it's tuned to 5 Hertz 🤣🤣🤣
@@jasonmelo1974 in this big a box, you don't need that long a port to get low, especially if it's not particularly wide.
The "11 Hz" PA speaker was an H//H Pro 150. I added a piece of cardboard pallet wrap tube to the hole where the bullet tweeter was. Later I entered the paramaters in Hornresp, given the box was just over 100 litres (4 cubic feet). This enclosure will function as a large sealed box, although maybe in the single digits there might be some boost, although the displacement of this driver is likely not enough to take advantage of it. You'd get better SPL just tuning to 40 Hz.
Edit: I just did the calculations for 4 cubic foot box with a 4" wide pipe 12" long and it comes to between 24 and 25 Hz in half space. Still too low though for the type of speaker I wanted, which was a party/PA speaker for maximum punch above 50 Hz. Quadrupling or maybe 5 or 6 x port area would have got me there.
I didn't know that PVC pipe can be useful for bass resonance 😀👍
me too
What frequency is it tuned to?
Shroom frequency
@@nigelm.steele9329 I like it, posting from Colorado, though it has been a minute since I did some.....
I like the no port at all approach best (correct if you guessed sealed;).
Genial parabéns vou tentar fazer um dessa amigo
not good as u people but this system according to me will not boost lf. a folded horn type will be much better option.
Would have been helpful to show how powerful it was with a meter or something. And a contrast with and without tubing.
Parabéns achei muito interessante
You are so amazing
Not gonna work. Sorry, it's a bad build.
It's poor quality of phone's bandwidth
You're here because you're cheap. Want better, buy better.
Bose use to make a speaker like that in like the 80s or 90s. In the commercial they’d cut the speaker in half to show the same tube like structure inside. I’ve always wanted to make one.
mendingan pake dekat Dari kayu aja...
mungkin jangka pendek sangat bagus
tapi Kalo jangka panjang suatu saat pipa Akan buat getaran Yang mengganggu..
tapi overall mantap Dan mampir ya
Nice job construction, but you should invest a bit more into the quality of the woofer and definitely add a Tweeter with the crossover and put more thick cables plus the finiture design outside then you good to go...

Or buy some TDL Studio 1s like I did. Phenomenal bass response. Try Welcome to the Machine by the Floyd. Have fun!
Very talented 😊😻😍
seems like its closer to a t-line concept than anything else. i was kicking around a similar idea but instead using 6 inch pvc pipe and fit a 6 inch sub in the end and run about 8 feet of the pipe. im pretty sure that if you have the ports firing the same direction as the sub yours will sound much better than it currently does. as it stands you have opposing waves cancelling each other out.
I have always liked tube equipment 🙂
My thoughts on this: I do not own a CNC. I would use real wood. I would add material inside the box to minimise dead air space. Finally, I would buy speakers from some company that saves me all the work. My Image 200 speakers from the mid 1980s have excellent bass. Have fun to all the DIY guys out there.
