I have a budget of about $1200 on speakers for a 5.1 setup. I am new to this forum and I have not seen much about in wall speakers so I am not sure that they are the speakers of choice. I would like to go In-Wall with the right, left, and rears. I would like to place the center channel on my tv, with a sub in the back of the room. Please advise what kind of speakers I should check out. I also have a budget of 400-500 on a Receiver. Any good suggestions for the above would be appreciated?
