EchoBuster products, Does anybody use them?

i mounted 4 door-sized echobuster panels to my cathedral ceiling (!) due to an overly reverberant room. i honestly didn't know if it would work or not, but they (EB)custom made and boxed the panels for me. well, they work. there is still a tiny bit of liveliness to the room, but i think a very small amount makes a positive contribution- if i had ended up muffling the upper mids and treble too much, it would have ruined the experiment. anyway, i ball-parked it, and still came out ahead. others should take a more educated approach than i did, but i kinda knew instinctively after a few years how much of a problem i had just by walking around, talking or whistling (!) and listening to the amount of delay/echo. and it's great when the tweeters in your speakers stop driving you out of the room...

Thanks French_fries, every little bit helps.

I have two of the 12"x48" panels and am still trying access the best placement for them. I can tell you that curiousity go the best of me and I peeled the backing loose to see what was inside and I was very disappointed.
Especially when I looked at the cost. They are basically a Sonex panel 4)2'x2'panels are 75.00 at Audio Advisor. I can only say that the Echo Busters I own will be the last.
I figure I can make wooden frames and buy fabric and have 4)2'x2' panels for about 100.00. As for the performance of the product, yes it makes a difference, but not sure where they best assist the sound.

I might suggest that you investigate some of the products marketed to the pro audio community. These folks are ultra critical and rather knowledgable about acoustic concerns with regards to setting up studios and control room environments. Some of the products are, I might add, not inexpensive. You can scout a few forums for tips and advice; www.recording.org , www.johnsayers.com , www.homerecording.com are a few places you can go. You can check out the specific forums for acoustics and/or studio design and get lots of general info on acoustics, DIY project tips, and pointers towards quality manufacturers of acoustic treatments. Ethan Winer's products have a pretty good rep and you can check those out at www.realtraps.com. He also has a lot of interesting information on his website and for many links on studio acoustics, go to http://www.theprojectstudiohandbook.com/articles15.htm

I think they work great. My dealer uses them. But only if your into dropping a lot of money. To treat my room with Echo Busters, the cost would be around $5k.

I chose diy.
