I've already considered it with my current speaker, but just in case I do buy a new one I may wait a little: My TV rests on the top shelf of a 3 shelf TV stand with my center on top of my DVD player on the second, what I plan on doing is...
Here's my current set up: TV: Panasonic TC-P55ST30
Receiver: Onkyo TX-NR609
Front speakers: Infinity P363
Rest of speakers from HTIB Onkyo htsr800 7.1 (next project is to upgrade center channel)
DVD: Oppo DV-980H
