Subwoofer in Box

I have a similar situation...Never thought of using that space for a sub! Might just steal that idea! If I were to do it the think that I would strive for is to make sure the sub box is not fastened to the wall. And if possible, have the sub facing toward the room. I would probably basically build a heavy cube into the wall out of 3/4 MDF or an even more dense sheetgood if I could find it. Seal it all up, slide the sub into the cube facing out and then cover with GOM or speaker cloth. Not sure if I'm verbalizing what I'm thinking but I hope you get the idea.

I think it would effect the sound but not sure in what way. I'd be afraid of standing waves, reverberations and such inside the wall cavity/cube.

Sconner, I agree completly with what you are saying. You don't want any vibration trasmitted to a DVD player or something above it, so make sure the box doesn't touch any walls. Probably the easiest way to make sure it doesn't touch is to use some of those pads that they sell at the hardware stores that interlock together for areas where you are standing alot. Cut some of that to fit.

I have a pair of subs in enclosed cavities under my equipment cabinets. Here is a picture of one:

Here is a pic of the overall framing early on:

A few comments:

- You don't mention if the bottom of your rack opening is directly on the floor (i.e. no framed in bottom) or not. If you are still in-process, then try to make it so if you plan to put a sub in there.

- Frame the enclosure as rigidly as possible... glue, screws, and thick plywood.

- Make sure you have a front firing and/or ported sub

- I lined the inside of my enclosure cavity with 1" Linacoustic

I'm very pleased with the results....

(You can slick on the links above for more pics...)

scaesare, can you please fix your links as I would like to see the pics.

Ths links work as long as you don't have a firewall blocking HTTP access to ports other than port 80.

Cool!

I had the Linacoustic leftover from doing my internal room sound treatment, so if you are planning on doing any of that, then you can use the same stuff. If not, then it's a little on the expensive side ( I paid ~$120 for a 100' roll).

Also I didn't put any Linacoustic on the bottom of my cavity, as my subs sit directly on the floor carpet.
