The room size is 12' x 16' but open on 2 sides.
I have QS4'S on the ceiling on the open sides and QS4 on the wall on the other side.
M60's and VP100 up front. All sound ok with the volume on the receiver at -20db. But when the EP125 is turned lower it does not have the same impact.
I live on the other side of Cambridge.
