I am looking to get my first HT system for my family room. I am considering the Polk OWM3's for 6 of the speakers, a Polk CS10 for the central, and the Polk PSW505 for the sub. The opening on my TV stand won't hold a standard sized receiver, so I am looking at a Marantz 1604. My family room is not that big - 15X13, but it is already wired for 7.1. Any thoughts on this system? I know tower or bookshelf speakers would be better for the L/R, but my wife doesn't want anything that big. I am also considering the OWM5's for the L/R, and just using the OWM3's as satellites, but the OWM5's are pretty big.
