I just moved into a new condo. I want to create a media wall that looks really high tech and cool. What you see on this photo is a 70" Vizio LED/LCD . I have a floor standing PSB speaker in each corner and a large center channel speaker that is blocked by the TV. The unit in the niche could serve as a cabinet to house the electronics, which I have yet to purchase. The length of the wall shown is 18' and the room depth is 25'. I'm going to have a sectional couch and I plan on hanging the TV on the wall just to the right of the niche as close to the center of the wall as possible. any ideas or advice is welcome. Here is a photo I found online that echos the type of design I'd like to achieve.
