EchoBuster products, Does anybody use them?

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.

I highly recommend reading the Room Acoustics Forum (sponsered by Rives) on Audio Asylum. Both Rives and Ethan Winer are active participants and there's ton of good information regarding room acoustics, panels, traps etc.

If you want to get into it deeper there are a number of other resouces including Ethan's excellent web site, the Master Handbook of Acoustics etc. If you want professional assistence, Rives also offers three levels of consulting services with specific recommendations. The more you learn, the more you understand that it is not a nebulous realm, but a science. And being a rocket surgeon doesn't hurt. ;-)

I've made a number of bass traps and absorbers for my room based on some of Ethan's designs and using Owens Corning 703 and 705 products. If you have a basic woodshop and a few skills, you can produce some very professional looking products that work extremely well. I decided to go the DIY route in order to custom build what I wanted in both terms of coverage and appearance. The fact that the price is significantly less than commercial products is a big plus.

In order to see some of the effects of bass trapping, you can buy bags of insulation to stack in a corner - not pretty, but very fast and affordable. Rigid fiberglass panels can be stacked or set in corners etc. to give you an idea of the possibilites.

IMO, a properly treated room is more important than any single component you can buy.
