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

Thanks for the response. Unfortunately REL is cost prohibitive. Hope you enjoy them.
I had an L12. It was defective, so I returned it for a refund. Went to a JL Audio e110, and it's far superior to the Rhythmik. Just my $0.02.
At it's price, the e110 SHOULD be better than Rythmik's entry level sub! That's like comparing a Toyota Corolla to a BMW 3-series.
Thanks for all the comments, I certainly appreciate the opinions. I have no doubt the sub brands mentioned are very good. How good is the question? Since I have budget constraints I need to go with best-bang-for the buck.  Will the Boom Boom sound of the JL e110 sound three times better the the Rythmik? I guess I will have to drive my Toyota for awhile longer.
 Thanks again.
