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?
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.
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 still have a cassette deck. But your idea of the doors is not new. I have a Kriesler stereogram from 1968 with sliding doors at ends over the speakers. So it looks just like a nice cabinet when not in use.
You are not old.... I had an 8 track in my first car. 😉 I still use an 8 track in my workshop. I have an old stereo from early 70s that way I don't have to worry about theft or damage. Many years ago my father would pick up 8 track tapes for me at yard sales for ~$0.10.
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 like watching videos about speaker designs on small speaker systems to get maximum bass output because I would like to use the same designs but on a much larger scale with 12 inch subs. Videos like these gives me ideas. Thanks for uploading.
Please add thick cotton liner on all the walls inside the box. Add some rubber gasket ring in between Speaker & Box before screwing up. Pure Bass Sound in fact True Bass Sound will come. You will love it. And yes I loved this project idea. Love from Bharat to you 👍🏾
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.
how do they appear unmatched? why do you think your calculations are more accurate, as if he didn’t do them beforehand. i’m sure they must sound like shit for him to keep building them. the length of that port is critical for lows. doubt he just winged it for the sake of views.
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.

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....

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.
I would call it a rattling wave damper. Look at the device of the pipe of the old gramophone. 📯 Gradual diameter transition and proper swirl to gently remove other noises. The volume of the box must be in proportion to the room so as not to create resonance. And some polyurethane foam inside
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.
It's possibly a cross between a ported box and a transmission line, but it goes against the accepted methodology for making either . Maybe it could be considered to be a 7 ft long pipe speaker. Maybe a bass reflex box with a 7 ft. long port However, I wouldn't be surprised to find an empty cabinet of the same size (without the ducts), with a hole in the cabinet having the diameter of the pipe, could sound similar.

If you cut the MDF on a cnc machine, why do all the sanding and grinding? Why the last bend on the port? It only directs the opening chose to the front... Why not place the port openings on the front and not the back? Why make two ports and not just one? Did you do ANY calculations to the port and the length? I have NO suggesting as to what you should make next, but I would suggest anything else than a speaker enclosure!😝

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.
Go on the diyaudio forum, the have a section on subs, and there's some VERY knowledgeable people on there, only too happy to help anyone, no matter if you're a beginner or not.
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
I use this same type of tube system for my car. But the chamber where the speaker goes is also tube. The guy here still used a box though. It’s my favorite and best for anything below 25Hz! My tube complete tube system is about 25lb compared to a conventional bulky square box that needs bracing would be 80lbs which for a daily vehicle sucks. Ever since I discovered tube systems, it’s all I use for Bass systems!
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!

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.
If you do, definitely use a better driver (subwoofer) with a bigger magnet, better terminals, better quality rubber surround that allows the cone to move with greater excursion, and use thicker-gauge high-quality speaker cables for both the internal wires & connection to the amp. I'm not sure what kind of amp this is, but it doesn't seem to move the driver cone very far, this could be the fault of the amp, the speaker itself, the wiring, incorrect impedance (Ohms- for example car audio equipment almost always runs at 4 ohms, unless subwoofers are specifically made to run at less, like 2 ohms/ 1 ohm because the lower the impedance the more power it can pull from the amp, as long as the amp can handle it as it will generate more heat & require greater electrical current. Most decent modern car amps are made to easily withstand this kind of power draw & heat. Condider this also: I'm) it could just need level/ frequency adjustment at the crossover/ filter
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).
@@jasonmelo9379 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.
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.

Hi what is the formula for the relationship between frequency and length?
What do you even mean? The output from the port is shifted by 180 degrees from the output of the driver so you never get cancelation between the driver and the port at the tuning frequency and up. It doesnt matter how long the port is, the length affects just the tuning frequency.
Nhìn thấy co ống Bình Minh là biết bạn người Việt Nam. Tôi là một người thợ điện tử đã nhiều năm (60 t) nhận xét: bạn có sáng tạo, nhưng loa sẽ nghe không hay đâu vì lượng không khí bên trong loa số với ống hơi không được cân. Lưu ý là ống hơi nếu dài phải đi tù nhỏ ra lớn như saxo và phải có thể cắt ngắn hay thêm độ dài. Chúc bạn vui.
Длину волны нужно учитывать при вычислении длины фазоинвертора. А вы этим пренебрегаете.
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.
If you cut the MDF on a cnc machine, why do all the sanding and grinding? Why the last bend on the port? It only directs the opening chose to the front... Why not place the port openings on the front and not the back? Why make two ports and not just one? Did you do ANY calculations to the port and the length?
I have NO suggesting as to what you should make next, but I would suggest anything else than a speaker enclosure!😝

I like all but the hot glue never had any luck with hot glue putting anything together but overall great video
Gran trabajo, me parece una excelente propuesta para controlar el réflex, no sé si calculaste el drenado para llegar a esos diámetros y recorridos considerando sus curvas, así como el volumen del cajón.
Pero se escucha sensacional.
Felicidades
En que ayuda esos tubos ? Tengo un parlante video similar y quisiera hacerlo como del.video.
А как ты звучание оценил? Неужели через свою аппаратуру?
Через наушники слушал, умственно неполноценный?
Дружище, заметь пожалуйста, я тебя не оскарблял. А твой негатив скорее тебя ставит в ряд неполноценных. Задумайся.
@@user-jb5uf1dl9o между прочим, во время поворота - звучание заметно изменялось. То есть, по меньшей мере, у автора микрофон был стерео.

Very nice experience 🇹🇿🙏
so creative and beautiful
"Good speakers have tubes?" "Hold my beer!"
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.
Wow! it sounded like Blue Man Group Drumbone!

I have a 10" subwoofer. Could you please give any idea to get the most punch sound?
Go on the diyaudio forum, the have a section on subs, and there's some VERY knowledgeable people on there, only too happy to help anyone, no matter if you're a beginner or not.
Verdaderamente GENIAL
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
Awesome. Where do you find small speakers with xmax large enough to pull this off?
I use this same type of tube system for my car. But the chamber where the speaker goes is also tube. The guy here still used a box though.
It’s my favorite and best for anything below 25Hz!
My tube complete tube system is about 25lb compared to a conventional bulky square box that needs bracing would be 80lbs which for a daily vehicle sucks. Ever since I discovered tube systems, it’s all I use for Bass systems!
It's bullshit ....
Systems has valves are stoves I use integrated amplifiers stable on two hom By car
@@zip.gianni4045
You are ignorant.
Where can I learn about this? There has to be more people doing that.
@@zip.gianni4045 what?
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!

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.

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.....
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.
que top da vontade de fazer uma igual
If you do, definitely use a better driver (subwoofer) with a bigger magnet, better terminals, better quality rubber surround that allows the cone to move with greater excursion, and use thicker-gauge high-quality speaker cables for both the internal wires & connection to the amp. I'm not sure what kind of amp this is, but it doesn't seem to move the driver cone very far, this could be the fault of the amp, the speaker itself, the wiring, incorrect impedance (Ohms- for example car audio equipment almost always runs at 4 ohms, unless subwoofers are specifically made to run at less, like 2 ohms/ 1 ohm because the lower the impedance the more power it can pull from the amp, as long as the amp can handle it as it will generate more heat & require greater electrical current. Most decent modern car amps are made to easily withstand this kind of power draw & heat. Condider this also: I'm) it could just need level/ frequency adjustment at the crossover/ filter
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).
With a port that long I assume it's tuned to 5 Hertz 🤣🤣🤣
@@jasonmelo9379 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.
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.
