I wouldn't be so hung up on Rythmik. They make good subs but don't believe the hype that their technology makes their subs so much better than competing subs. If I were you, I would just look for a good deal. If Rythmik can import one inexpensively, that would be good. I don't know if Paradigm, being a Canadian company, sells their subs for less in Canada than the USA, but if you can get a deal on a Defiance X12, you should give that sub strong consideration. It will majorly outperform a Rythmik LV12r.
