Paul,

I did the same thing that you are thinking of. I have cherry up front, maple in the rear. the maple are nearly off-white (whatever that means...) I bought white grills for the QS8s and slapped em up on the wall. They are my own little "custom" job. I find that they blend into the walls better than a black or cherry speaker would, and are therefore rated much higher by the wife.

Here's a pic - sorry for the size.
