First, whats the difference between their rm20 set and rm 6900? Only thing I can see is that theyre different colors, other than that I'm not too sure. http://www.polkaudio.com/homeaudio/products/rm20/ http://www.polkaudio.com/homeaudio/products/rm6900/ Has anyone had expierence with these? Theyre going for ~700 on clutchfield with the PSW10 subs right now . I live in a condominium so I dont really need a huge setup. I'm going for a 5.1 surround with hdmi since i have a ps3 and hd cable box running. I also won't need a seperate dvd player since I will be using the ps3. Also I'm trying to decide between the Onkyo TX-SR604 and Harman Kardon AVR 245 right now. I've heard good reviews on both of them can someone recommend me one? Thanks alot!
