Hello - I'm looking for LCR speakers on a budget of $700 to $900. My TV is 58in and is mounted above a fireplace, but the fireplace is on a wall that sticks out into the middle of a room, so I'm worried about speakers that are open in the back since the area behind the sheetrock is likely open. I don't have any HT at the moment, so anything will be an upgrade. I understand that enclosed speakers drive up the price. I'll use it mostly to watch TV and movies, and music every once in a while. I've had a hard time figuring out if speakers like this exist in the price range. If they do, any recommendations?
