Homemade sound panels

I made panels for my room and they were most effective. There are plans out there describing type of damping material, fabric covering, size of panel etc. There are specific materials to use. It's worth the effort, your room acoustics count as much as the gear you use.

Before you make your own panels, have a look at these. Excellent price, and I have been happy the results in my listening room with four of their 2 x 4 foot wall panels.

While I have the ones that Goheelz mentions, I happen to like the ones from this company a lot better.

I second Duke: in my experience all the so called anti reverberration acoustical panels make the sound dead. Diffusors do work but in the majority of cases you should use bass traps. There is one caveat though: bass traps are bulky and you'll need lots of them to get significant reduction of room modes. If a room sucks, you'll never get good sound, even with extensive acoustic modifications.

OC703 is the material of choice for many DIY panels. It comes in 1" or 2" and maybe even thicker 2'x4' sheets, usually in '6 packs'.
You Tube (no kidding) has a couple vids on such constructions.

My plan is to treat '1st reflection' points and the back wall of my listening area. This will reduce the echo type effect while leaving the rest of the room fairly live.

Don't overdo it!
