DIY acoustic panels?

I took a look at gikacoustics.com and thought the sound absorption panels were actually pretty good and reasonably priced, but I am interested in making my own to better match my room.

Does anyone know what type of cloth is good for sound absorption, hopefully something that is readily available at fabric stores?

Be aware that the denser fiberglass (such as the 8lb Roxul Rockboard 80) does not work effectively if you start layering them past 2" or so.  If you want a really thick bass trap (such as 6" - 8") it is best to use 3 lb panels, such as Owens 703.

@bobk3 That's exactly what I did for my dedicated HT room. I built 14 4x2 Ft panels using Roxul 80. Worked very well. I used an acoustically transparent black grill cloth from Fabricland. Check your local fabric shop, the may have something similar.

I know someone who can probably make them look like amazing art work.

I will be combining my audio and video equipment, which means a large TV on the wall behind the stereo equipment. Will the glass on the TV affect the audio? If so, should I build panels to cover the TV?

I am not sure about the bass traps. They might be overkill for the stage I am at.

i have been looking at the new PB Ultra subwoofers from SV Sound, however, and they claim dual subs can help smooth out the bass frequency  responses.

another thing about Roxul 80.  They are extremely heavy when compared to Owens 703.  (almost 3 times as heavy).  So if you are mounting on the wall, it may be better to get the lighter 3lb stuff like Owens 703.  However, the Roxul 80 will have better absorption in midbass (such as 100-150hz).
