I love this design and the idea behind it 100%, but I wanted to let you know that you're causing resistance to propagate and build up against your sound waves as they're trying to exit that pipe. These are called standing wave reflections. See every time you have a pipe joining two elbows together you're creating a lip on the inside and that is not going to put clean sound through there. you need to make sure it's smooth on the inside and you will actually lower the bass range on it and improve that solid bass tone. I recommend cutting and gluing together pieces of that 42 mm elbow it seems to be perfect.
@@jlove24 huh? He just said to just glue the elbow pieces together instead of adding the pipe on the inside to remove the lips which will catch and disrupt the waves?
@@sammyspade123 yeah you can see inside the pipe when he does the thing. You can also tell that the elbows he's using aren't the kind that flare out to accommodate the diameter. Not too sure about the nomenclature, but I know it's a thing because I have them under my bathroom sink.
It's all very nice to be able to see the workings but thick MDF would give a much better performance because it wouldn't resonate as much as the thin plastic. There should also be fibre packing inside the cabinet to prevent reflected sound in there. It's a novel idea but it sounded like a speaker in a drainpipe to me. With that CNC router, you could make a far better enclosure.
In fairness m8 to watch this and say you could have made better is pointing out the already blatantly obvious. That is not the point of this video. Just my humble opinion offered without prejudice
Adding fiberfill does not prevent reflection of sound, it only makes the sound waves take longer to bounce off the walls of the enclosure basically mimicking a bigger enclosure.
@@viixy364 That's a terrible attitude to have. David was giving constructive criticism, which in the world of DIY is VERY useful for innovation. How else would things ever improve? Plus, David's comment helps everyone that's looking in the comments. Think about it, chances are there's someone in the world that's going to use this video. They are probably going to read the comments TO FIND OUT what possible issues there are with the design before actually making it themselves.
My mannequin girlfriends and I would love to dance to one of these super duper bump'n thumper's! We could frolic to some "safety dance", "Don't you want me", and "Relax" before coming back here to tell you all how this isn't a subwoofer and blah, blah, blah and how I should know since I'm a suck woofer, a sub woofers cousin!
I'm building subsonic active subwoofers, which with only 100W power amplifier, sounds like the 1000W one. What I see in this video, it's purely a cartoon. The sound of this subwoofer would be a crap. It's not working like that. The air is so much compressible, that would not come out anything from that box, at that length of the tube. Anyway, looks amazing satisfying, so more people are watching, more money are going there. The box with thin walls, it's too much flexible, so rendiment is lost with the vibration of the walls. The speaker is barely moving, so not enough air pressure it's created, it's just a wasted material. Not a good idea to follow.
I like it and I can appreciate the hard work and creativity that went into this project. Tips to improve the design in a couple areas is to use larger diameter pipe and taper it off to the rear side. This creates a pressure difference in the pipe and reduce the pipe reverb. The other thing is to actually glue the piping together since the vibrations over time may cause it to fall apart in weak spots. Also if your going to use plexiglass to show off the cool internal design you should try to use opticlear caulking since that will dry clear and you won't see the irregular bead pattern. If you don't want to use caulking you could router in a press fit groove around the base. Normally the professionals would use MDF board all around due to density and reverb cancelation to deaden the sound to just get the bass and the channel noise but then you wouldn't see the cool pipe pattern. In the future you could try using a flat board of foam core board and mount a driver straight to the back which would cause the flat board to become the speaker itself. That way you can have cool prints on the wall that are actually speakers.
Speaker design and performance is a "black art"😳. This is just art 😁. The port of a bass reflex speaker, which this speaker is pretending to be, requires an analysis of the driver parameters to enable the correct amount of air movement to match the driver and enclosure size. The volume of the cabinet is usually specified within a limited range, otherwise the amount of air to move is too much or too little. The opening size and length of the port are calculated to match the driver specs and achieve the output desired by the speaker designer. The port is frequently referred to as a "tuned port" for this reason. Speaker cases are usually made from a dense and inert material like mdf. This material helps prevent resonance of the cabinet impacting the sound output. Thin perspex like this will resonate, perhaps rattle at one or more frequencies. The speaker cabinets I have made in the past, (from a KEF kit) have used 2"x4" bracing between opposing sides, to eliminate any resonance. The sound output from this speaker would be almost the same if the driver was mounted on a flat board. Have a look at the Klipschhorn speaker design. They are drawings on the net. These are marvelous "horn loaded" speakers essentially bass reflex design that uses the walls of the room as an extension of the speaker. These are an example of powerful yet VERY efficient speakers. The speakers in this post are more for visual appearance than for quality sound output. Best wishes... 😊
very interesting acoustic development, the tubes are resonating a frequency similar to artists who play various lengths of tubes with a table tennis racket.
@B.L.A. it is. Material properties matter for stringed instruments but are not super important for instruments where the air is being excited by some external thing like your mouth in a brass instrument
@B.L.A. no need to be expert. if it is about 30x30x30 cm it got ~27 Liters volume. With 40mm Pipe at a length of maybe 100 cm. Calculated in WinISD this would be a tuning frequency of 12-13 Hz. Pretty low for a driver this size
A cool video on how not to build a speaker enclosure. That is unless you're a big fan of farty bass and just love the case trying to be part of the driver at very inconvenient resonant frequencies.
Это креативная штука,можно на выставку ставить как экспонат,выглядит забавно,конечно в прпвильности звучания нет смысла говорить.За прделанную работу лайк🙂👍
believe it ir not, that concept was invented by bose almost 25 years ago. i don't think this guy knows this. but ur design is better than what bose ever came out with. very impressive
Looks unusual. But this is not only not a subwoofer, but also not a normal sound column - plexiglass is not the best material for the case of such devices, the bass reflex line is clearly not designed. But beautiful. 😁
Look at this video on youtube it explains how to match the port size to the box and balance it out against the speakers low frequency. : ruclips.net/video/U5BQdnagzW8/видео.html
Hmmmm... I wonder how this design fits the theory of creating low frequencies and accurately reproducing them at the right moment without delay and distortion. I would just like to understand the logic of the constructor. The trumpet, I think, will bring its own sound different from the original conceived by the sound engineer, undoubtedly due to its length and resonant phenomena in it.
I think this is just for show or stunt.. i don’t think the tubing has anything to do with the enhancing of bass- if you want to see the kind of tubing or concept anyway- the Bose subwoofer is there
@@Mr.Justanotherdude A properly tuned port constructed this way should work just fine. This was not properly tuned, so who knows where its resonance is. Try smacking one open end with a sandal, that should let you tune it acoustically without doing any math.
There is a little distortion I'm hearing, I'm thinking it's from the position of the port opening, inside the box. I believe it's catching some distortion direct from the speaker wave. if you turned that opening 180* (aimed straight at the edge corner) might get a cleaner signal as some of that distortion might be removed by bouncing the back wave off the box before going into the port. Very cool design though, just think a little tweaking might help
Now I wanna see you do one that has a tweeter 8 inch a mid range and a 12 in sub then 3 different size pipes that wind around each other .... cool speaker though dude! Might try and make a similar piped setup for the sub sonic base frequencies prolly with carbon fiber pipes
It's a really nice display of how to build a nice looking but poorly engineered "subwoofer". However, if you take it as a method and not as a cookbook recipe, you can alter the dimensions and the active parts however you like. The point is that snaking that tubing together is easy peasy, it can be built to any arbitrary length for tuning, and it's not going to leak enough to matter, if you have to bang on it to get it together. That's the main takeaway. The second takeaway is how to make an enclosure out of acrylic panels, but we can see similar demonstrations in many other places. I'd be inclined to make it with four or five MDF sides and just one or two acrylic panels so the user can see der blinkenlights. Also it would fire down, not forward. And I'd find a stage to use screws instead of adhesives, for maintenance reasons. It really helps to be able to take a side off repeatedly without causing damage, although the rest of it can be glued and siliconed.
better wood could be used, plus cutting the edge across the knot and using that piece is just classy. The use of hot glue is another example where there's better options. I'm not sure which adhesive is used for the assembly, but no doubt that an acrylic welding cement would be a better choice for bonding those pieces together. Why bother counter sinking the speaker when the result is a weaker and thinner mounting surface? Why not Polish the edges where all cuts were made? I love the soldering iron. Where did you get it from ? Grandpa's wood burning kit?? What kind of solder is that? Acid core plumbers solder? this video keeps on showing up in my recommended videos, so Congrats on the views.
Funny that the title says DIY but he uses a cnc router table instead of a table saw. Every DIYer has seen or used dozens of table saws, but most will never see a router table.
i like the show off aspect of this project. it gave me an idea for this dj subwoofer project im thinking of building. i want to make the front baffle plexiglass and use some led lighting to flash with the beat however, i have the same question as yours. i'm figuring that since it would only be the front, and i use egg crate sound dampening, that it won't affect the sound that much so yeah i'm also curious about this
There's not really any pressure considering driver size and power. It'll be shown on a sensitive mic but not the even the most trained ears could detect it.
The port inlet that's facing the sub... Have you tried turning it 180° so it's facing the back wall of the enclosure? Think it would make it sound better but worth a try.
I’m hearing hi-freq. The typical frequency range for a subwoofer is about 20-200 Hz for consumer products, below 100 Hz for professional live sound, and below 80 Hz in THX-certified systems.
So it needs a Tang Band sub and a crossover, but that would do almost nothing to the actual construction method which is frankly the most interesting part to me. I can just open software and design a tuned port enclosure, but I hadn't thought about how easy it would be to snake those particular parts together. Now I'm almost certain to do this, although maybe not for this particular purpose. I'd much rather make it bigger, and be able to tune it. I could extend the tube outside the box and then back in so I could add crooks to it like natural horns! 😆
It cut out a circle and the box size... You could do this with harbor freight hand tools, or even a rock from your yard if you had enough gumption. Are you daft?
You could do this with a hand router if you had to. It would be a much bigger pain, but you'd get there. You can watch guitar builders shape bodies out of slabs of random-thing-set-in-epoxy, they use templates made of MDF to guide a router, then use the router to guide itself to deepen the cuts. That's pretty much the same process the CNC is doing, it cuts most of the way through on the first pass and then slowly and carefully finishes the job for better edges.
The guy doesn't know how to do math at all, he can't make a simple calculation of the phase inverter, and he doesn't know about pipe resonances at all, he got glue, how else did he not stick to this box himself.
The tuning frequency? My guess is that you don't know. I know without calculation that the tube should be under 10 inches. Even if the tuning frequency was suitable for the speaker, the design of the tube is terrible with the turns. Also, the enclosure material is way too thin. So really, this is just something to display on a shelf, no other function.
@@markj5032 There's a ton of information available for free to anyone and this guy decided not to use it. This "subwoofer" sucks and that's a fact. If that offends you, too bad.
That Bluetooth circuit should have some way of changing the equalizer settings or extra circuits so the different sound ranges can be outputted to the different output screws
if you had done a sound test of the phone before and then the phone through the speaker before we could have a proper control to test whether the sound is better or not. with this video we have a cool looking box
Cool see thru box, now I could add mixers to the actual video and such to make it seem like the sound is from the speaker and that it’s clear vocals/ bass… so where the proof of powerful? Decibel ???? Or what does that means to you? I’m just wondering, As for looks yeah it’s kinda cool to look at.
This is just a monoral speaker with a reflex port. As others have noted, a subwoofer is a loudspeaker designed to reproduce low-pitched audio frequencies known as bass and sub-bass, lower in frequency than those which can be generated by a woofer. The typical frequency range for a subwoofer is about 20-200 Hz for consumer products, below 100 Hz for professional live sound, and below 80 Hz in THX-certified systems.
I wonder where did you get those frequency ranges. Any full range speaker of decent quality goes well below 100 hz and as far as I know PA subwoofers go higher than consumer ones... For good sound quality a subwoofer shouldn't play anything higher than 80 hz or so.
@@penttijakonen3817 A lot of lower end equipment will let you go up to 200Hz or so. My sony 10 inch sub says up to 200Hz on the frequency response specs. That doesn't mean it should, but it can. And yes full range speakers usually go lower then ~40Hz but some people use a dsp to high-mid pass filter the main drivers. Then let the sub take over the rest. That puts less stress on your main drivers. Generally speaking though us 2 channel audio guys don't even use subwoofers.
Based on its post's "Very powerful subwoofer" we should only hear 'thumping' ... I called it a full range coz I can hear all the frequencies all the way! 😏
It looks cool, but that PVC pipe isn't moving all the main airpressure because it's mostly capturing remaining atmospheric pressure after-the-fact. You're constricting the airflow. Sure, the base driver will move and it will resonate the plastic and wood surrounding it, but as a "labyrinth" air chamber this won't work. You could have easily done the same thing by putting in a slab of wood at an upward angle behind the bass driver with a 2 maybe 3 inch clearance, then have a 2 to 3 inch port for the exhaust. To make your design work, you need to encapsulate the air behind that bass driver and ensure that the majority of that air exits through the pipe. You could augment this design with a funnel at the tip of the PVC aimed at the bass driver.
I've thought about making something like this with a telescoping section, slide-trombone-style, for tuning purposes in conjunction with a test-tone CD.
Props to your design but, the title is more aptly suited as " Interesting Midbass Enclosure" as, previously stated- no sub bass frequencies were produced. Add a 1" silk dome tweeter to this enclosure then, add a backlight, while making another for a set of bookshelf speakers. You could run them through the power of a Marantz home amplifier while adding a transmission line 8"sub enclosure to play in conjunction with the bookshelf speakers for rich full sound.
Interesante proyecto, suena bien, tiene base para mejorar los efectos de sonido... Particularmente me hubiera enfocado en colocar la salida de aire en doble posición frontal. Sabemos que su acústica se basa en bajas frecuencias por lo tanto su fondo debe ser de uno y medio por tamaño del parlante, aquí se le fue la mano, en este caso es necesario para que tenga lugar suficiente y acomodar el tubo de PVC que retrasa el sonido haciendo que sus decibeles sean proporcionales. Tal vez en un futuro trabajo se pueda colocar un twiter.
ME parece que es muy grabde la caja, para el tamaño del woofer y lapotenica le fata no?, esa tarjeta como que es de baja potencia,el woofer se ve que da para mas aún.
Nice idea, not so nice execution. Is this even a subwoofer driver? Have you calculated the bass reflex port lenght, diameter and frequency response? Why didn't you apply a lowpass filter for demonstration? Why did you put so much effort in cnc milling that beautiful casing but then making a pretty hefty mess with that silicone? Why did you go so fast through the wood with that endmill and put so much effort in post processing the edges of the cuts? Have you considered using an up down cutter? So many questions. 😅 Well.. but you created something! Nice Idea as I said!
Using those particular plumbing parts to make a tuned port is a great idea. As for finding drivers, go to Parts Express. I like the way he made the box and the port, and I'm fine with them even though neither one was engineered to any spec, because the methods transfer just fine if we decide to change the dimensions.
I would of use epoxy to bond the acrylic, glued the pipes together, and cleaned up the wires personally. Still looks neat though, maybe could of incorporate some RGB as well.
I too like the design. But is missing vital info such as the dia of pipe and elbow's and the length's he cut, over all well done. Now my question for all. What about using threaded elbows and pipe, bonded together? Would that make a difference?
Quite literally could have made a bazooka sub, but make it like a M202 FLASH rocket launcher with pvc tubes for 2 smaller mids, and one Sub and that would be badass. Smaller size, and could paint it green and not worry about the acrylic and use MDF wood. I respect the creativity, but for that size you can put a speaker on three more surfaces, and rearrange the pvc to channel each

I'd be inclined to make it with four or five MDF sides and just one or two acrylic panels so the user can see der blinkenlights. Also it would fire down, not forward. And I'd find a stage to use screws instead of adhesives, for maintenance reasons. It really helps to be able to take a side off repeatedly without causing damage, although the rest of it can be glued and siliconed.
better wood could be used, plus cutting the edge across the knot and using that piece is just classy. The use of hot glue is another example where there's better options. I'm not sure which adhesive is used for the assembly, but no doubt that an acrylic welding cement would be a better choice for bonding those pieces together. Why bother counter sinking the speaker when the result is a weaker and thinner mounting surface? Why not Polish the edges where all cuts were made? I love the soldering iron. Where did you get it from ? Grandpa's wood burning kit?? What kind of solder is that? Acid core plumbers solder?
this video keeps on showing up in my recommended videos, so Congrats on the views.
Good job kipitup
Very cool.
Funny that the title says DIY but he uses a cnc router table instead of a table saw. Every DIYer has seen or used dozens of table saws, but most will never see a router table.
This kicks ass
I wonder how much energy is lost using the plexiglass walls.Might it perform better with dencer wood walls?
i like the show off aspect of this project. it gave me an idea for this dj subwoofer project im thinking of building. i want to make the front baffle plexiglass and use some led lighting to flash with the beat
however, i have the same question as yours. i'm figuring that since it would only be the front, and i use egg crate sound dampening, that it won't affect the sound that much
so yeah i'm also curious about this
There's not really any pressure considering driver size and power. It'll be shown on a sensitive mic but not the even the most trained ears could detect it.
The port inlet that's facing the sub... Have you tried turning it 180° so it's facing the back wall of the enclosure? Think it would make it sound better but worth a try.
Genau 😘👍👊 1m bis 1,20 Bassweg 👏
This is just a Bluetooth speaker. It definitely sounds like it has pvc inside of it. Pvc has a distinct sound when sound waves pass through it.
Ae Việt Nam mình nghiện chế cháo loa quá anh ơi 🤣🤣🤣
Interesting!
This is a kucluk kucluk tabembeng ta gantong..yeeessss
this is piping good
I’m hearing hi-freq.
The typical frequency range for a subwoofer is about 20-200 Hz for consumer products, below 100 Hz for professional live sound, and below 80 Hz in THX-certified systems.
Because it's not a subwoofer, just a normal driver.
So it needs a Tang Band sub and a crossover, but that would do almost nothing to the actual construction method which is frankly the most interesting part to me. I can just open software and design a tuned port enclosure, but I hadn't thought about how easy it would be to snake those particular parts together. Now I'm almost certain to do this, although maybe not for this particular purpose. I'd much rather make it bigger, and be able to tune it. I could extend the tube outside the box and then back in so I could add crooks to it like natural horns! 😆
PVC pipe is like Legos for maker projects
ah yes...DIY....if only i have a CNC milling machine
It cut out a circle and the box size... You could do this with harbor freight hand tools, or even a rock from your yard if you had enough gumption. Are you daft?
You could do this with a hand router if you had to. It would be a much bigger pain, but you'd get there. You can watch guitar builders shape bodies out of slabs of random-thing-set-in-epoxy, they use templates made of MDF to guide a router, then use the router to guide itself to deepen the cuts. That's pretty much the same process the CNC is doing, it cuts most of the way through on the first pass and then slowly and carefully finishes the job for better edges.
Dat Prime Thanatos
The guy doesn't know how to do math at all, he can't make a simple calculation of the phase inverter, and he doesn't know about pipe resonances at all, he got glue, how else did he not stick to this box himself.
Thank you
Your soldering iron looked like it was the size of a persons thumb. 🤔 good idea nonetheless 👊
Good job kipitup
The tuning frequency? My guess is that you don't know. I know without calculation that the tube should be under 10 inches. Even if the tuning frequency was suitable for the speaker, the design of the tube is terrible with the turns. Also, the enclosure material is way too thin. So really, this is just something to display on a shelf, no other function.
Thank
No other function except to play music like he demonstrated.
@@JohnEboyee That speaker would work better without that pipe.
You build one better then Mr know it all and make a video on it 🖕
@@markj5032 There's a ton of information available for free to anyone and this guy decided not to use it. This "subwoofer" sucks and that's a fact. If that offends you, too bad.
That Bluetooth circuit should have some way of changing the equalizer settings or extra circuits so the different sound ranges can be outputted to the different output screws
I loved it so much! Really 😊👍
Thank you
May be you like it But don't understand how?
Because is your music experience poor like this?
Plastic and 90 degree turns probably sounds like added reverb or hall effects on the 90s eq 🤔
if you had done a sound test of the phone before and then the phone through the speaker before we could have a proper control to test whether the sound is better or not. with this video we have a cool looking box
Cool see thru box, now I could add mixers to the actual video and such to make it seem like the sound is from the speaker and that it’s clear vocals/ bass… so where the proof of powerful? Decibel ???? Or what does that means to you? I’m just wondering, As for looks yeah it’s kinda cool to look at.
Dang it actually got louder in my truck than usual when listening to a song on my phone
This is just a monoral speaker with a reflex port. As others have noted, a subwoofer is a loudspeaker designed to reproduce low-pitched audio frequencies known as bass and sub-bass, lower in frequency than those which can be generated by a woofer. The typical frequency range for a subwoofer is about 20-200 Hz for consumer products, below 100 Hz for professional live sound, and below 80 Hz in THX-certified systems.
its not even a sub
Thank you
I wonder where did you get those frequency ranges. Any full range speaker of decent quality goes well below 100 hz and as far as I know PA subwoofers go higher than consumer ones... For good sound quality a subwoofer shouldn't play anything higher than 80 hz or so.
@@penttijakonen3817 A lot of lower end equipment will let you go up to 200Hz or so. My sony 10 inch sub says up to 200Hz on the frequency response specs. That doesn't mean it should, but it can. And yes full range speakers usually go lower then ~40Hz but some people use a dsp to high-mid pass filter the main drivers. Then let the sub take over the rest. That puts less stress on your main drivers. Generally speaking though us 2 channel audio guys don't even use subwoofers.
@@willtachi101 Well yeah, they allow it. But it's not a "typical frequency range" by any means.
Not a subwoofer....more of a full range speaker! 😏
the box is just a baffle for the woofer... pipe does nothing at freq that is playing.
has absolutely no concept of Thiel-Small parameters.
Based on its post's "Very powerful subwoofer" we should only hear 'thumping' ... I called it a full range coz I can hear all the frequencies all the way! 😏
It looks cool, but that PVC pipe isn't moving all the main airpressure because it's mostly capturing remaining atmospheric pressure after-the-fact. You're constricting the airflow. Sure, the base driver will move and it will resonate the plastic and wood surrounding it, but as a "labyrinth" air chamber this won't work. You could have easily done the same thing by putting in a slab of wood at an upward angle behind the bass driver with a 2 maybe 3 inch clearance, then have a 2 to 3 inch port for the exhaust. To make your design work, you need to encapsulate the air behind that bass driver and ensure that the majority of that air exits through the pipe. You could augment this design with a funnel at the tip of the PVC aimed at the bass driver.
Not a subwoofer, but a full-range speaker. Nice bluetooth project.
I've thought about making something like this with a telescoping section, slide-trombone-style, for tuning purposes in conjunction with a test-tone CD.
Go for it, but please post a you tube video 👍
Such a unique concept for a woofer with great sound.
Props to your design but, the title is more aptly suited as " Interesting Midbass Enclosure" as, previously stated- no sub bass frequencies were produced. Add a 1" silk dome tweeter to this enclosure then, add a backlight, while making another for a set of bookshelf speakers. You could run them through the power of a Marantz home amplifier while adding a transmission line 8"sub enclosure to play in conjunction with the bookshelf speakers for rich full sound.
Cool little project, really thought you might seal the woofer with the port tubing
Looks interesting, but try playing 23-35Hz on it to realize that it's far away from being subwoofer...
yo cool project. and you just gave me an idea for this subwoofer i'm thinking of building. thanks a lot
Seems like very deep bass when listening to this in my phone speaker. 😅
Should be use pointing d ground ..for a subwoo surrounding effect..
Cool! I would like to see it in brass and burl.
Interesante proyecto, suena bien, tiene base para mejorar los efectos de sonido... Particularmente me hubiera enfocado en colocar la salida de aire en doble posición frontal. Sabemos que su acústica se basa en bajas frecuencias por lo tanto su fondo debe ser de uno y medio por tamaño del parlante, aquí se le fue la mano, en este caso es necesario para que tenga lugar suficiente y acomodar el tubo de PVC que retrasa el sonido haciendo que sus decibeles sean proporcionales. Tal vez en un futuro trabajo se pueda colocar un twiter.
ME parece que es muy grabde la caja, para el tamaño del woofer y lapotenica le fata no?, esa tarjeta como que es de baja potencia,el woofer se ve que da para mas aún.
Nice idea, not so nice execution. Is this even a subwoofer driver? Have you calculated the bass reflex port lenght, diameter and frequency response? Why didn't you apply a lowpass filter for demonstration? Why did you put so much effort in cnc milling that beautiful casing but then making a pretty hefty mess with that silicone? Why did you go so fast through the wood with that endmill and put so much effort in post processing the edges of the cuts? Have you considered using an up down cutter? So many questions. 😅 Well.. but you created something! Nice Idea as I said!
Using those particular plumbing parts to make a tuned port is a great idea. As for finding drivers, go to Parts Express. I like the way he made the box and the port, and I'm fine with them even though neither one was engineered to any spec, because the methods transfer just fine if we decide to change the dimensions.
Now, I want t9 make one...thanks
I would of use epoxy to bond the acrylic, glued the pipes together, and cleaned up the wires personally. Still looks neat though, maybe could of incorporate some RGB as well.
Clean up that caulking alittle and you could sell those things easily
I too like the design.
But is missing vital info such as the dia of pipe and elbow's and the length's he cut, over all well done. Now my question for all. What about using threaded elbows and pipe, bonded together? Would that make a difference?
what a soldering iron......
Quite literally could have made a bazooka sub, but make it like a M202 FLASH rocket launcher with pvc tubes for 2 smaller mids, and one Sub and that would be badass. Smaller size, and could paint it green and not worry about the acrylic and use MDF wood.
I respect the creativity, but for that size you can put a speaker on three more surfaces, and rearrange the pvc to channel each
