Echo Absorber™ Acoustic Panel Install

I run a nightclub and our sound system has a lot of power for the size of the room, so the echo was getting pretty bad. I needed to take care of it quickly so waiting on fabric wrapped panels was not an option. I talked to Drew and he told me that the best way to go would be the Echo Absorber. Ideally I would’ve liked a different color, maybe like a red, but I went with the white and regardless of the color this stuff works. Even when only half the material was installed I could hear the difference. Thanks a lot for the great recommendation.
