I'm about to under take the project of purchasing my surround speakers to start building my system. I'm limited on my knowledge of system set up, thus my question. We just had our house built and I thought I would be smart and have them pre-wire for surround. Well they did but I think the placement they used might be too high on the wall. Here is a photo of the placement. I hope to get a 42" Plasma to mount on the wall about 12" higher than the TV set is now. Any suggestion s would be great. I was looking at the Bose (I know, I said I was new) or an in-wall speaker. Any guidance would be great.
