So far of all the contenders, the speakercity.com sub using an NHT-1259
http://www.speakercity.com/subwoofers.shtmlSeems like a killer deal. A sealed, powered sub that is very similar to the bottom part of the NHT 3.3 speaker.
Flat bass to 23hz, usable bass much lower.
I like the NHT specs, and was wondering if anyone has experiance with this sub?
