Ok, I'll probably get flamed for asking, but here goes. I have a client with a 5.1 system installed by another company. The fronts are in-wall, rears are in-ceiling. The center is an average-sized cabinet-style speaker that currently sits behind a 55" LCD on its stand inside built-in cabinetry.

Obviously the center speaker doesn't perform well in this configuration. I don't have the height in the built-in cabinet to raise the TV, and there's no place for an in-wall center. I haven't found a center speaker or passive LCR bar short enough to not obstruct the TV.

So here's my question: could I use the center channel pre-out of the AVR and feed that into the analog input of a short (<3" tall) powered sound bar?

I realize there would likely be lip-synch & volume control issues to overcome, but could this theoretically work?

Relevant equipment is Sammy 55" LED, Yamaha Aventage AVR, & C4 processor for control.
