I just installed some GIK Acoustics in my listening room. I notice now that the room is quieter which is to be expected. However, I also notice that I have to turn the volume up on my sub now in order to get it to read 75db. The volume goes from 1 to 99. Before the bass traps, the volume was on 8. Now, with the bass traps, the volume is now on 20. Is that because of the Bass Traps that I have placed in the corner along with the rest of the acoustics panels that I have hung? I only put the bass traps in the front of the room. Am I really hearing the sub now and not the sub and the room together?
