I have moved to a new house and had to leave the in-wall speakers at the old house. Any comments on using some full-range tower speakers for the rear channels in DD 5.1? I am tempted to do so because the surround channels are full-range in 5.1. But I also know that most people use smaller wall-mounted speakers, and that many of the speakers designed for rear surround do not radiate sound directly from the front of the speaker. Any suggestions? What are the pros and cons? Thanks for any help.
