Good but Cheap Treatments for Flutter Echo

I assume you're walking around the room, clapping you hands and hearing it? Try a tapestry, or a quilt in the location. I use the ASC wallboards..about $50 each...but the look good.

Maybe also a shelf (or several wall sconces) with some odd shaped objects...anything to break up the refections...mine was high up...like 6-8ft where the furnature wasn't killing the bad vibes....

Check garage sales and antique shops for a folding room divider or screen. They come in many sizes. Some 3,4 and more folding sections. This can be covered in any favorite material and placed in a strategic area to work great and actually look nice.

Bosch, are you the one who posted about doing a diagonal room setup? I am, too and for the slap (flutter) echo I purchased two sets of Golden Sound Acoustic Discs. It was either those or buying/making triangular pillows. Having heard the DIY room lenses in action, I decided to go for the Acoustic Discs, as they work similar in principle--diffracting sound waves.

Best in your project, and keep us posted. You can send me a private e-mail if you wish.
