Rythmik subwoofer

I am new to this forum and looking for opinions on moderate priced subwoofers to pair with Magnepan 1.6 speakers. I am presently testing Rythmik L12 (entry level) subs. These are servo subs and sell for $535 each. Does anyone have experience with Rythmik? Also considering SVS subs. Priorities are sound, price, size and looks ( need to keep wife happy).
 Thanks
