Well, the scary thing for me is that I have heard the occasional creaking coming from my speaker/TV. At least, I think it *might* be from that, I dunno. The creaking is always brief, like a single creak, not a long creaking. And it's usually pretty soft in volume, and happens maybe a couple times a day.
I'll try to describe the pics that I've attached. I used to have a speaker mount on the wall for the centre speaker, and its height was perfect for my older, smaller TV. When the new HDTV came along, the height of the speaker mount was too low. And because of sheer laziness, I didn't take the mount out of the wall and put it higher, I stacked some wood (from an old DVD stand) on top of it, placed a couple short pieces of wood forward to rest on top of the HDTV, then placed the speaker on top of that. Is this a really bad idea? Should I think of doing something else for the centre speaker?
By the way, that little thing in the centre of the wood there is just a little lamp, to provide some illumination behind the HDTV when watching at night.
