What are the best Room Accustic Treaments members have found?

"The suggestion of crowded bookshelves, curtains, carpets and clutter is no more than guesswork. Adding any or all of these will have an audible effect, unfortunately it probably isn't an improvement. The books will just collect dust and the drapes and carpet are only narrow- band absorbers."


Wrong, but as elsewhere, you`ll need some skills and patience. You need to know what you are doing. Listen to this guy, he`s a bit skilled:

A few decades of experience helps as well... and not backing down to the 

If I were designing a recording studio, obviously a whole different approach is required. However, the last thing I want in my media room is recording studio acoustics.

I made my own bass traps and absorbers with corning 703 and muslin and wood.

davidrolson, forgive me if you already know this. Room treatments generally address damping (absorbing) or redirecting sonic reflections. if you do some research, you'll have a good handle on what your room "needs" Many of us have made absorption panels with OwensCorning foam insulation installed in frames with nice fabric covers. It sounds like you've made the first step to realize you want to treat your listening room; many never do that and IMO that's the primary building block to a good listening experience. Good luck.

I agree with tuberist's comments as cost is a big deal to me. FWIW, I have about $22,000 of stereo gear at list price that cost me about $7,000 used. Never bought new. I looked at GIK pricing and figured I could save half by doing it myself: make panels with Owens Corning absorbing material, lumber for frames from Home Depot, and fabric from Joanne's Fabrics.

Now would these go in a formal living room? Probably not. Would they do well in a well decorated man cave? Probably; I know I am happy with the result.

Also, my personal opinion is that foam products do not work as well as Owens Corning (or Roxul Rockwool) because foam has have lesser absorption properties.

All sorts of questions to ask yourself!

Thanks for listening,

Just installed GIK diffusors and they work great.  Addressed some smearing and focused up the vocals.  Bit more control of bass.  I also have 6' quarter round ASC treatment in the corners.
