Where is the best place to position your centre speaker if you have a rear projection TV? My TV is a Tosh 42wt29 and the top of the TV is only around 3-4'' wide. Do I just balance the centre speaker (B&W lcr60) on top of the TV or is there somewhere else I can place it. I don't have the glass cabinet for the TV so there is nowhere underneath the TV I can place it, unless I buy the glass stand of course but that would mean the speaker is virtually on the floor? Is this adviseable? What about a shelf slightly above the TV, would that be practical?
