I'm certain there are other treads regarding this topic, but the search function seems to get stuck in a loop when I use it. I just ordered a Sony 50" SXRD TV (KDS50A2000). I'm going to need a place to put my Polk Audio CS300 center channel speaker. I'd like to keep it on top of the TV if possible, so I've been looking at buying this. http://www.bestbuy.ca/catalog/prodde...7&catid=21248# Are these safe for the TV? My only other option is to put the speaker on the lower shelf of the TV stand. I'm worried that would sound strange. All comments and advice are greatly appreciated.
