DIY sub bass tube from PVC

[@trinjaminternational]

I was looking for a good outdoor waterproof subwoofer and found the same issue with the expense...I've built many boxes so that was not going to work for me. Thanks for your video...the PVC formed the basis for my waterproof speaker build..I already use quite a few Planet Audio amps and speakers so that also sealed the deal for me. I used a little more recessed seating for the speaker 3/4 mdf and covered in abs plastic on both cylinder ends ... will post a video review after and cite you for credit of course!

[@1BionicRooster1]

Your cut away work clips crack me up. Good video.

[@eddieg.jr.4044]

Thanks! I try to make it fun

[@Geo76er]

Good video. This inspired me to build my own. I built two today, but double the length of yours. I'm also gonna put a 2 inch port in the back of each one. They're going to reside in each back floorboard of my vehicle.

[@salvatoreizaiah3511]

I guess I am kinda randomly asking but does anyone know a good place to watch new tv shows online?

[@eddieg.jr.4044]

Cool. What speaker did you end up using? What “vented enclosure volume” did your speaker call for? Interested to find out. The specifications sheet provided with nearly every subwoofer gives both vented and sealed enclosure specifications for optimal performance. Some also give exact vent measurements for length and diameter of vent tube. I was shooting for compact as possible and the coupler just happened to calculate to the exact volume for sealed enclosure for my particular subwoofer. Thanks for the comment.

Man I would love to have this for 2 10’s

[@eddieg.jr.4044]

I recently found a place that sells PVC by the foot and from 1/2” - 24” diameter. I would use 12” diameter and install one in each end. Also be sure to calculate the volume of the enclosure based on the specs for your particular subwoofers. So just as an example…. 10” Subwoofer “x” specification sheet calls for a sealed enclosure volume of a range of .65 - .75 cubic feet. So 2 subwoofers would require 1.3 - 1.5 cubic feet. So a 12” PVC cylinder that is 22” long would give you 1.44 cubic feet of volume. That would produce some SERIOUS BASS! Thanks for the comment.

[@LIFEINSPEED]

Awesome work bro! Just Install passive radiator on the back so you can here allot dipper bass

[@ericperry72]

Interesting idea. I was just thinking about a 8" or vetter yet a 10" pvc pipe cut to size so I can install it behind my headlight on my Suzuki M109r and run a pro audio 8"/10" inside. Thanks for posting this.

[@Brianwarner1782]

Not sure. Why no one else caught this.. But the radius is not 8 inch. That's the diameter. The radius is half. Which would be 4in.. u then take 4² x Pi, Then multiply that by the height and that's how you get volume. I only know this from calculating port area on speaker boxes as well as using Radius times Pi to calculate subwoofer cone area... Point is, the volume of that is about a quarter of what that speaker needs....just saying.

[@julioyperla]

I did this some couple years ago but I did use a 10 inch schedule 40 pvc pipe with a really cheap $20 walmart woofer put it behind my seat of the truck that was a extended cab and let me tell you , everybody that heard the system that I had to 12" in there. I'm going to try to do this again just got my hand on a 12 " pvc pipe.

[@dontkarebear9485]

These comments kill me. "You did everything wrong! Nice video "... I think it's ingenuity & exactly what I'm going to do. Except in wood. With different dimensions. And a port. And 2-15" speakers.

[@SlowRiderDucati]

Great job. They sell the PCV "glue" at home depot as well. Basically sets in seconds.

[@eddieg.jr.4044]

I considered PVC glue. But as I was glueing wood to pvc, not pvc to pvc, I didn’t think what would work. I could be wrong. The Gorilla glue has held strong and stand by my decision of its use in this application. Ty for the comment.

[@SSSSSteaLeR]

TLDR Spec sealed enclosure = 680 in3 PVC enclosure built ~ 490 in3 If you build a box smaller that manufacture spec, the sound will not be as loud as designed, and will start to distort at a lower power. Mistake #1 - Volume of the enclosure You calculated the volume of the EXTERNAL dimensions of the enclosure. External dimensions of the ideal sealed box = 18.5" x 5.5" x 11.5" equals 1170.125 in3 Internal dimensions of the ideal sealed box using 3/4" MDF = 17" x 4" x 10" equals 680 in3 (this is the volume to match) Mistake #2 - Volume of the coupler You calculated the volume of the PVC incorrectly. You did r (radius) 8" and h (height) 5.75" equals 1156.11 in3 .. this is just completely wrong Radius of a circle is 1/2 of the diameter. So in this case you need to measure the internal diameter of the coupler. Actual r (radius) 4.3125" and height of 8.4" equals 490.78 in3 Assumptions 8in Subwoofer Planet Audio AC8D www.planetaudio.com/product/car-audio-sound-system-auto-stereo-dual-voice-coil-subwoofer-planet-audio-ac8d/ Subwoofer Manual www.carid.com/images/planet-audio/subwoofers/pdf/ac8d-users-manual.pdf 8in PVC sch40 Coupler - $17 www.homedepot.com/p/DURA-8-in-Schedule-40-PVC-Coupling-SxS-429-080/203218411 Length listed on the link above is 8.4" PVC Pipe sch40 8" = Diameter of 8.625" (this pipe should slide into any 8in coupler)

i want to put a bass tube in my car an 8 inch sub woofer i like my sound and bass to only be in the car i'm not trying to be heard and seen and having everything rattling i don't like that shit. i want some that's not going to take up too much space and does the bass tube comes with an amp built inside so i don't have to buy a amp to run my bass? i have 4 speakers two 6x8's and two 6x9's so i need a 4 channel amp to run them and the bass tube have it's own amp and all i need is somebody to install everything right

[@sagered8007]

I like this kid.

[@JDCowboy]

You made a mistake on the calculation the radius is half the diameter. So the tube needs to be twice as long.

[@JP-xg8cd]

Hell yeah that’ll work!

[@junaidgt90]

Bro. I think you need to glue some noise dampeners stuff on the surface inside of the tube Plus you may have to have a small opening for the compressed air to move in and out. Nice DIY B.t.w 👍

[@eddieg.jr.4044]

OffdaRoots thank you for the input. The hole I drilled for the wires I sealed from the inside with goop. A thick silicone. As for the dampener material.. could you explain further as to why? Thank you again.

[@junaidgt90]

Eddie G. Jr. to be honest, this is what i learnt from youtube.... Small hole 2 - 3 inches wide and attached to that is another pipe with the same inch as the hole that runs half the length of the bass tube plus all of the inside walls covered with some cotton like fibrous stuff... You need to chk other videos to get more clues... and pls share with us your thoughts on this. Best of luck 👍

[@eddieg.jr.4044]

OffdaRoots I see.. you are suggesting that I need a port. This speaker’s specifications call for a sealed enclosure of this size. For a ported enclosure it calls for a larger cabinet. I wanted to go with the smaller more compact sealed enclosure for space saving in my truck. Thank you again for your input.

[@eddieg.jr.4044]

OffdaRoots in the video you will see the instructions on cabinet volume. The speaker came with both volume dimensions for sealed and ported. 1:12 in the video.

[@eddieg.jr.4044]

Waylon Stokes I took your advice and put some pillow padding into the tube. The difference in sharpness is noticeable enough to say its a must. Thanks for the suggestion. I put in about 1/3 of the padding from a standard pillow.

Hi thanks for sharing your experience,i was thinking just that as a solution and you came just in time i need it! But i was hopping to have a little bit more music time with different types of songs. Also i wanna know if dimensions matters,i mean if the cubic inches are the same but the one is lets say 12" height and more compact length is the sound quality the same?

[@eddieg.jr.4044]

Tribal Dragon the airspace is what is the important. It can be any shape as long as the cubic inches are there.

[@beardedg500]

Isn't too small?? Does PVC gives a good bass??

[@JasonWW2000]

You need to measure the air volume and compare it to what the speaker maker suggests. Also subtract for the air that the speaker displaces. It doesn't have to be exact, just close in size.

[@evazkee7246]

Sweet. I'll put a port in mine. Maybe 2"

[@eddieg.jr.4044]

E vazkee most subwoofers come with detailed cabinet dimensions regarding optimal volume or size measurements for a ported and/or a sealed enclosure. Once you pick out your speaker look at those numbers. Then, decide if you still want to put a port in your tube. Let me know how it turns out.

Just cause you put a speaker in a tube doesn’t mean it will sound good. Where the sound test. I see it moving but don’t hear anything. Definitely is cool idea though

[@bunnatang2081]

try passive radiator on other side.

[@audiogman5865]

In order to use a passive radiator you must first design the enclosure as if it was to be a ported design because passive radiators exhibit the same characteristics as a ported design. Then you have to select the right radiator and then tune it to the same frequency as if it was a port by adding or subtracting weight to the radiator diaphragm to achieve the correct resonant frequency. It’s not just a matter of sticking a passive radiator on the other end. There’s a science to it.
