Just wondering if anyone could help me out on specs and a bit of a "How To" build a tube for a 10inch MTX thunder sub? I know that you use PVC piping but just asking if anyone builds/has built one to kinda give a run down on the procedure.

Cheers GMB

Look at the spec sheet you got with your sub!

It will tell you the correct volume you need for a sealed and ported box, it will also tell you the diameter, length and number of ports requried. Adhere to these specs strictly as if you dont, the sub will sound very bad

EEERRRR in correct, would you like to phone a friend. I dont want to build a ported or sealed box as i have done that in the past. Specs on the sub dont come into the way i build the "TUBE" not box as i know its got to be 2 feet per sub and obviously the correct diametre for the woofer to fit with the MBF ring cut inside the PVC pipe. What i wanted to know was has anyone built them in the past and if they could give me a step by step kinda guide for that and the process that they used.

As for adhearing to the specs that the manufacture give you i think if you ask anyone that knows what there doing when it comes to subs that there not worthe much as every woofer is different and every install the driver is going to be used differently!!!!

Not having a go at you Badhabit as i know you work in this industry but im sick of people telling me to adhere to the specs if i want to buld a ported/sealed box. I want to build a TUBE not a box as its lighter, not as big and easier for placement and removing in and out of the boot. Thanks for the reply and dont take my post the wrong way at all as im not having a go, just venting some steam after getting home from work. :)

Ahh sweet dude, I mistook what you said, thought you meant 'ports'

Well, I dont have too much experience with a Bazooka styled tube, but I see no reason why pvc pipe wont work, just make sure whatever you use is solid so there is no flex!

I agree, bass tubes are easier to move around and can give awesome bass if made correctly! Hope that helps a bit more

What i'm after is an elxploded diagram or a set of build instructions for making a tube if you know where i could get my hands on a set?

if you have the recommended volume for the sub then a bit of calculation is all that is really needed. to make one I would start with a 300mm dia tube. fill the ends with 20mm mdf and seal it WELL. fibreglass resin would be a start. ( this is for the back of it.)

for the front cut the hole for the sub. as a rule its usually 25mm less than the sub size.

for ports if the volume is correct then the recommended size will work fine.

( have done a few of them.)

Do a search on home theartre subs. I know there are quite a few people who have built them for this application and got good results. I remember seeing a tutorial somewhere on the web..

I'll see what i can find!

Could you let me know if you find something?. I want to do the same thing in the back of my R32 and mount it in the boot under the parcel shelf.

I was thinking of using mdf and building a false floor but i agree its too much weight.

I dunno about using PVC pipe though unless it was pretty thick stuff, i figured it would sound a bit funny even with baffling.. ?

I have built 2 now. One with cardboard and the other PVC pipe. The PVC sounds better in my opinion but everyone is different. Not much to them really and it doesn't take all that long to make them, just have to be precise with your measurements and cuts and screw/glue it all together.

Tell me what ya want to know and i'll try to help ya out. I'll post some pics up when i get my camera back and if i ahve time i'll put up a vid of what they sound like :D

Kool ive got a few Questions :P

Where the hell would i find 10" PVC pipe ? Are the pipe walls really thick and you can screw the sub into em? or are you sealing it with something? or both?

did you try with/without baffling?

How does it look ? i want to carpet mine and make it nice and mount properly.

your happy with it?? compares well to a MDF box?

Movie!! I be happy with a few pics though :)

Go and check out you local plumbing store as they can get it for you or do what i did and went down the road where there are some road works being down and water mains being replaced ( found this method a lot cheaper too :wassup: )

You cut up MDF rings that you screw/glue to the inside of the PVC and cut the inlet out for the sub and screw the sub to the MDF ring.

My tubes are ported so no baffling and i dont think you need it as there a small enclosure to begin with.

I have carpeted one and sprayed the ends that i got and i have made up some mounting blocks so i can strap it down in the boot.

I think they look ok for what they cost me and the job there doing.

I have only hooked them upto a friends amp so far which does not have a low pass filter or a inbuilt x-over either but they both sound pretty good.

I'll get some pics up asap and let me know if i can help ya out at all if you decide to build on???

Im gonna give it a shot. As long as the price is right. i was told 300mm pvc is $65 a metre by bunnings (they dont keep any on hand) Ill ring around some plumbing places tomorrow and see. And then the dude at bunnings was going on about how shit it would be and to build a wood box instead. pffft.

im gonna make one and ill compare it to my premade 10" box. Even just in the name of science. Ive got a couple of ideas for the look of it too so i hope it works out.

so yeh some pics would be great. [email protected] if its easier and no one else is interested.

another alterative is to make two rings out of MDF so that they are larger than the outside area than the sub itself (so that you can bolt it onto it) cut the hole out for the sub to sit inside of, then after you have taken your measurements of how long it is going to be, get about 4 lengths of wood (does not need to be very thick ) and attach each end to the MDF Rings this should give you a skelital shaped cylinder get some speaker cloth and wrap it and secure it around the shape of the wood frame making sure it is nice and tight, make up some resin and apply to cloth allow to dry (about 12-18hours) then add you fibreglass you will need about 4 layers of resin and glass once this is dry you have a totally sealed light weight tube, then it is just a matter of sanding and putty and more sanding then you can paint it or cover it in a nice cloth of some kind - to give it more bass you can stuff it with a filler

It would be hole heap easier if you were to just use cardboard to wrap around then fibreglass that instead of the cloth!!!

Thats the way i built one of them and the other out of PVC just to see which one was better.

Working on those pics :wassup:

interesting though. Ive never looked into using fibreglass . i just want to keep this one simple and cover PVC in carpet. The small idea ive got is putting a thin neon light inside the tube and cut out the word SKYLINE or something into the PVC.Then use some tinted plexi/perspex to cover underneath. Ill heat it up and form it into a curve to fit and make it airtight. Hopefully it will look the goods and not tacky

Gotta get the pipe and also figure out the airspace i need for a 10" kicker sub. ill do some searching on this unless its allways the same for basic 10" sub like mine?

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
