Building a 10" tube

[grandmasterb]

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

Kool ive got a few Questions

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

[hazerb30]

and this is a good idea

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???

[hazerb30]

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?
