Thanks for the responses.
I will try putting the Bose behind me and that should solve my problem.

BTW, the Bose Compacts are fantastic at reproducing the stereo piano sounds of my Yamaha CP4. I started with a single Bose but the resultant mono piano sound was really cheesy. Other, non-stereo sounds like guitar etc sounded fine. With two Bose I have one panned fully left and the other fully right and the great Yamaha piano sound is preserved.
