Hello all - I'm (finally) taking delivery of a panny 53WX42 today, and I was wondering if it would be alright to place my center channel speaker (20 lbs or so) on top of the set. I've heard of bowing experiences, but usually only with multiple items (like bulky receivers) on top. Thanks for your help! P.S. There were a few threads involving placing items on top of RPTVs, but those threads involved multiple items, so my question seemed a bit different. Sorry if my question is redundant.
