We currently have speaker wire hanging out of our walls in three rooms of our house and would like to hook up speakers (the actual stero system will come next). Here is my dilemma: we were planning on in-wall speakers but I am concerned about pulling out insulation to install them since three of the speakers are supposed to be on an outside wall. (I was looking at the Niles AT- and the Mirage i-6W for in-wall speakers and the Boston Acoustics BravoII for on-wall speakers. Any thoughts as to which would be the best for general listening? THanks so much!
