Plasma TVs and center channel speakers

I have been toying with the idea of getting a 42 inch plasma for my dedicated HT room. It will sit directly in front of a window on an outside wall based on the best layout for the speakers in the room so hanging on the wall is not really an option.

I have a Martin Logan Cinema center channel speaker which fits nicely on the 32 inch CRT TV that is in the room now, but it won't even come close to balancing on a plasma. Because of the window, I can't mount it on the wall either...

All the HT components sit in a 27 inch high 62 inch wide six compartment custom piece of cabinetry, so a fully new rack designed for plasma is out of the question.

Anybody out there have any ideas on how to keep the center channel speaker above a plasma. Somebody must make a stand for placement behind the TV that will hold the center channel speaker above it, but I can't find any such thing.

Have even toyed with suspending the speaker on steel cables from the ceiling, but don't really want to go to that much trouble, and have 20 - 30 pounds dangling above a $5k TV...

Thanks

Mitch
