Just order my sub today. I want to thank everyone that has taken the time to input to this forum. It helped make my decision much easier. I just updated a rather poor HT. I know that my components aren't top of the line, but its quite a step up for me. Here is my system to date: Panasonic 65" HDTV Widescreen Onkyo TXSR800: Receiver Polk Speakers: RTi100's (fronts), RTi38's (back surrounds), CSi40 (center channel), FXi30's (side surrounds), and my SVS 20-39 PCi + when it gets here, hopefully at the end of the week. I hope to get better separates and speakers eventually, however, this will have to do for a while. Hopefully I will still be able to sell what I currently have. It is fair quality stuff I think.
