Custom Subbox, how big?? Help plz?

[hideki03]

Hi,
i recently purchased a pair of 12' MTX 4000 series subs (400Watt) and i'm trying to figure out how to build a ported/plexiglass box for it... can someone point me in the right direction with, let's say, pics, dimensions, link?

thanks

If you bought them new, the suggested demensions should be in the box they came in.. For Sealed/Ported Enclosures.

My 12" 6000's I belive needed..... .80 ish cuft for Sealed box.
I went 1.0 Cuft per sub, with light insulation.

Material to use for building it is MDF 3/4". Actually. They are 4000 Series so 1/2" would probably be fine. But I would still stick with 3/4"

The ports you can make out of PVC pipe. Cut to the demensions that the subs need. You can also use vents insted, but I wont explain that.

By plexiglass, do you just want a plexiglass view ontop or something?
Basicly, Cut a Square or whatever shape you want out of the box, router the edge, slip the plexi glass in, and screw it in. (pre-drill the plexi first) Its better if you use thicker plexi glass.

really dont go any thinner than 3/4 inch mdf you wont get a truly sealed box with mdf either. if you want a sealed box use industrial grade partical board. mdf lets air threw its just compresed saw dust with no glue partical borad has glue. if you want a really sealed up box use mdf and paint the inside of the box with fiberglass resin. give it a few coats and it will be really solid, particla board doesnt absorb the resin as well.

I wouldn't say ported if you are a beginer theres too much stuff to take into account for it to not sound like crap. Stay sealed till you build a few boxes and get acquainted with theories that go with this ish. 3/4" MDF is all there is DO NOT USE ANYTHING LESS!!! I cannot stress this enough. The amount of power you are going to use also depends on how big to make the box, a generic box I would build you would be 1.3-1.5 total shared airspace.

(L*W*H)/1728 = Airspace in cubic feet.

Have fun and don't get discouraged when it doesn't turn out the way you want it just start over
