Howdy, peep's I'm looking for some help, direction or hints about wall treatments. This will be for my church, the side walls are concrete block and I'm getting a lot of sound reflection since we upgraded the speakers and I have adjusted the amps (800 Watt Crowns for each channel L/R/ Center Cluster and Subs). I used a sound meter to adjust all the amps and now I'm getting the reverb/echo stuff. I know all we need is to make or buy some wall treatments. I looking on the DIY side of things, for we have a carpenter on staff and I'm sure with the right guildlines I can help him put this together.

The size I'm looking at will need to be in the area of 10-12' by 12-14' Cover 3 section of the walls on each side total of six panels. This will cover the front side wall section of the church where the sound reflection is the problem.
