I currently have an audio system in my bedroom. Four Polk Monitor 40 II, Polk PSW 111 subwoofer, driven by Harmon Kardan 3490. I have been playing with the rear settings, but just don't know how I should balance the bass setting with the rest of the sound system. In addition, even though the bass speaker is 8", there is still quite a bit of booming, unfocused, unclear bass response. My other speakers are Polk that use a bass reflex system, and the response in those is much tighter. Any suggestions.....
