im looking to have a box built for my 2 15 mtx thunder 8000's that would be slotted. i already have a jl audio dual 15 mounting plate made out of fiberglass to use on the front so id just need the rest of the box built around it. locally every place want around 300 bucks, and a few online places will do it for 100-250 bucks with shipping. anyone here capable fo doing it for around that price?? thanks

 

why dont you just make your own they are really easy to make.

 

Are you just looking for a Box (i.e. normal, rectangle-ish shapes)? If so, skip the fiberglass, and make one yourself out of MDF. If you already have a circular saw and drill, you're set...

 

Boxes are wicked easy. Each speaker comes with a recommended volume of space it requires (unless it is a "free-air" speaker). Be sure to hit that on the head. Remember that is interior space, so take the thickness of the wood into account. If you are going to put both speakers in one box, design in a piece to separate the box in half. If it is a free-air speaker than I say make the box as small as possible.

Use 5/8" to 3/4" particle board (the real fine particle board, looks like saw dust that has been glued together). Draw the circle for the sub to fit in. Don't forget to leave the edge for the metal flange to sit on. Cut that with a jigsaw. Pre-drill all the holes for the screws with (8" to 12" spacing max). Personally I glue along each edge where screws will go. Drill a small hole for the speaker wires. Assemble. Caulk the inside seams and speaker wire hole of the box.

This creates a sealed box. It is much punchier, but not as loud. Ported are trickier. There the length, diameter and position of the tube are concerns. And something I have not looked in to.

Ask me anything.

 

He means MDF - medium density fiberboard. The stuff is heavy as hell, I built a bunch of cabinets in my garage out of it (not to mention many sub boxes).
They have it at my local Lowes & Home Depot, just ask one of the lumber guys there for 'MDF'.

 

Thanks. I was at work, and it just wasn't coming to me. It's heavy, yes. At least the guy trying to steal it will get a hernia.

 

Yea I just bought 2 very large sheets of it from lowes today for 22.93 a sheet. I am going to build a few new prototype ideas I have for my subs.

 

Hehe... I built a bunch of huge cabinets in my garage a while back. I had to unload 10 sheets of that stuff by myself... my back was not happy the next day

 

mdf is cheaper at home depot, than lowes... by like 3-5 bucks.

also, home depot will precut for like $.50 per cut. first 2 cuts are free.

 

The home depot here is in construction it will be open for business pretty soon which is good. I will have a lowes and a home depot about 5 minutes from my house
