o.k heres my problem. One side of my room has a window and the other side has a opening to my kitchen. Originally I thought my bass(kick drum and bass guitar) was always located on the side of the subwoofer because of the subwoofer. However I've noticed that even when I move the sub to the opposite side the problem still persits. As well percusion always come from the right side too. On other systems with the same music the percusion and kick drum are usually located close to the center. Does bass start in the upper octaves and if so what can be done to remedy this problem? Would better imaging speakers help with this? Im thinking going from the paradigm moniter series to the studio series. I've got fairly heavy curtains and the problem is still there.
