Ok, I'm not an expert. I have a big room. I have my RW-12 in the back,in the corner. The human ear can't pick up where the bass is coming from, range 10-15ft. I can sit on my couch and have a movie like Star Wars or Pearl Harbor in and not be able to tell where its coming from. Just check with you friends next door,cause you will rock your house. My house shakes. the door knobs, cabinet doors, wall's. You are going to love your RW-12. Just don't get all hung up on where the placement has to be. Just put it, and enjoy. Music sound great, I play a lot of blues and smooth jazz. The Cool thing about the RW-12 is the dial on the side, for the Volume. I have my Phase Control set on like 90, and my cross over control 100. I have all 35's all the way around. They sound so good with the RW-12. You will just have to play with it. Put in a few different kinds of music. Have fun and enjoy, I know you will. You will be listening to all your music over again. It just sounds so much better now. The way it was meant to be herd.....Dan.
