I use a Hsu Research VTF-2 subwoofer. It has a 10 in. down-firing woofer and a 150 watt amp. While it doesn't have the slam of other subwoofers it sounds more musical to me. There are two ports. With one of the ports plugged the woofer will produce clean bass down to 25 Hz. With none of the ports plugged the woofer extends to 32 Hz but has more slam; ostensibly this would be used for movies. I keep one port plugged at all times - I would rather have extension than volume. Check www.hsuresearch.com for more info. It retailed for $499 about a year ago.

I need help with narrowing down my sub woofer choice. I have $600.00 to spend and am not sure to buy used or new? My system consists of b&K AVP 1000, Citation 5.1, b&w dm620's and a nakamichi mb-10 using a x-dac. I listen to music but watch a lot of movies as well. I have listened to b&W and a few others but the bass seamed sloppy. PLEASE HELP Best regards Jim
