A lot of people on this board bash the Bose speakers. I doubt many of them have even heard them. I use Bose and I love them. I came home with some large speakers and my wife had a fit. After returning two other speaker systems, I ended up with Bose. I am running a new Onkyo TX-SR805 receiver with a 7.1 speaker setup. I started with a used Bose Acoustimass 7 for the front left, right, and center. Later, I added a Bose Acoustimass 5 for the rear left and right. Recently, I added a new Bose Acoustimass 5 for the left and right surround speakers. I also have a Klipsch subwoofer. My family room is around 18X16 with a 18 foot ceiling. My system will blow you out of the room at 1/2 volume. I think it's an excellent choice.
