Hi Everyone! I have a question for you. About what weight would you say is the MAXIMUM WEIGHT of a center channel speaker, that you would place on TOP of a Hitachi 46F500 HiDef Rear projection CRT? I have heard horror stories of the framework of the TV beginning to bow in the top center over time. I want to be able to constantly upgrade my system and part of that is getting a larger, more dynamic center channel. Suggestions?
