Greetings, nice site you have here. I've been doing alot of reading here, so much good stuff. I'm pretty new to the HT scene. I put together some components a few years ago, and wanted to add a Subwoofer to my system. I'm really looking for suggestions and information to make an informed decision on what subwoofer to purchase. It will be for HT use (mainly movies) and I'd like to stay under $500. This is my reciever ---> JVC RX-888VBK ,these are my main speakers ---> HLS810 ,and these are my surround speakers ---> FLIX20 . In the mean time I'll keep reading and learning. Thank you for your time.
