I need advice for treating my jam room. We play in my basement which is approx. 20' wide x 7' tall w drop ceiling tiles x 23' long. There is carpet down there and paneling. We hung heavy velour black curtains all around the band for looks and immediately noticed some deadening of echos. Next I made (12) 2x4x2" absorber panels from 2" oc703 and hung them every 8' or so around the room. Problem now is low mid mush. The room actually sounded more balanced w/o the treatment. I know I need bass traps but im not sure how / where to hang them with the drop ceiling and how many I would need. Any advice?
