Hi Jonathan, When you put the high frequency mini traps behind your speakers, what changes did it do for the sound?Also, I read you have to turn the volume up to get the same volume in the room as not having the traps in place. Would that require the volume turned up quite a bit or just a little?Also, can you tell me what a pair of the mini traps cost and do you have your's mounted out from the wall a bit? Thanks, Greg
