I'm considering using rock wool, a.k.a. mineral wool, a.k.a. Roxul for a bass trap. I found 13 cubic feet of it for cheap. My question about using it for bass traps though, should I compress it to increase density?

I'll have to back-track to a couple of years ago to show where I started the build from scratch but for now here is my current rendition. The room is in my basement. This is actually what I was keeping myself busy with the most while Sofi was in the hospital almost 200 miles away and I'd come...

I like to listen to music in 2 channel just much as movies in surround in my theater. I have some concert DVD's with 2 channel mixes included. Comparing the mixes though actually leaves only a few differences...in 2 channel gone is the elevated bass of LFE but it's just as enveloping a sound...

Has anybody ever tried using some type of carpet padding for acoustic control, like a bass trap? Did it help?

What would it take, acoustic treatment wise anyway, to cure modes at around 38, 50, 96, and 106Hz? They aren't really terrible, the worst is @96Hz going 6dB above reference.

Anybody ever wish, when tinkering around with a 2 channel placement and position that they didn't have to keep getting up to move their stuff? I have an idea for a kind of crude "track" to place your speakers on that from the listening position you can move them laterally by pulling on a cord...

In the adjacent space that your IB sub drivers are mounted into, does it matter what material the room is made of or what else is occupying the space? I'd like to find out if there is much of an acoustic difference between two spaces of the same shape and volume but different otherwise...such as...

I've been seriously considering building one...here's a build from one of a few sites I've found. http://www.subwoofer-builder.com/IB/IB-gallery.htm
