Has anyone used Echo Busters?

I'm going to treat my room with ASC or Echo Busters, but the ASC is more expensive. And now I am considering the Echo Busters. Is there anyone that has used the Echo Buster. Please give me your opinions.
I put them in a restaurant and they work great. The room had a tile floor and sheet rock ceiling. They took the drop ceiling and carpeting out. All the customers complained about the noise level. Since I put the busters in they haven't gotten one complaint. The room is 14x38.
I have had very little experience with ASC Tube traps, other than listening to some rooms that have been treated. I own the Echo Busters and I have had good luck. Their instruction manual is lacking, but if you have a good dealer you are in luck. The corner buster pieces are self explanatory. The bass busters can be used in the corners with the round section facing the room. Some rooms do better with the round section facing the corner. This is not suggested anywhere in the instructions, and discovered by my dealer by accident. Later he confirmed this use with the manufacturer, but only after he asked. The manufacturer never volunteered any of this information. The echo busters are explained reasonably well. I have no experience with the double busters.

If your room is reflective: tiles, glass, smoth shiny surfaces, I recommend their kit of 4 corner busters, 2 bass busters, and 3 echo busters. This kit might be enough to improve your room. From there some experimentation and your ears will dictate if you need to further treat.
I have seen them at www.audioadvisor.com at reduced prices.
I use the Bass Busters in each cornor behind the speakers. In my case, the improvement was worth the cost. Much better definition in the low bass, and more stable and focused imaging. I also use the RPG Pro Foam for wall treatment. I have not tried the ASC products, but they offer a broader range of bass trap options than Echo Busters, which are only available in quarter rounds.

The Bass Busters don't look like much in the pictures you see in thier ads, but they are quite heavy, and well built. I recently stumbled on a tweak for them. I had a set of Vibra Pods that were sitting un-used for a long time, because I never liked what they did under my components. I was going to throw them out, but just for grins I placed them under the Bass Busters. This seemed to improve thier effectiveness, but I have no idea why. Anyway, if you have not tried room treatment you should give either the Echo Busters or ACS a try. I think you will find the improvement they make far better than any interconnect or power cord upgrade that would be compairable in cost.
I forgot to say I put them in the ceiling half the recommended amount and they worked great.
I too was going to use the ASC, but Echo Busters were less money by far. I went with the Echo's and most pleased with the results. One bass trap in each corner, 5 absorption and 2 diffusers, as well as 4 corners. Work very well.
If you feel handy there are instructions for DIY versions of the asc traps, corner busters and room lens on audio asylum. Now that winter has showed up i'll be addressing a set of lenses for my room. too cheap not to try.
