Subwoofer options for Magnepan with crossover betwen pre and amp?

I'd like to offload the bass below 50hz to a subwoofer through a crossover placed between pre amp and amp; believe this will (a) help with stabilizing the Prima Luna amp by eliminating low bass clipping (b) remedy the lack of weight in the low bass with Magnepan 1.7's. Has anyone found a combination they liked for around $2k? I've seen Vandersteen 2WQ's mentioned, I suppose separate amp/crossover TBD with Magnepan DWM panels are another path. My main concern is a clean merge of the subwoofer with the SQ of the Magnepans

I have two Rythmik F12G with my 3.7i's, and they integrate fairly well.  They're connected to my ARC Ref5SE line out.  I have a slight dip at 70hz that I haven't figured out how to remedy yet.

limniscate, you're a perfect candidate for the Rythmik/GR Research OB/Dipole sub. Details on the GR website and it's AudioCircle forum threads.

I need to call Rythmik. They're in my city and not far from me at all.

Your in Austin, ay limniscate? Check out an ol’ pal of mine from San Jose, Cornell Hurd. He fronts a Western Swing Band, and plays around town regularly. Cornell’s a great songwriter---Junior Brown for one has recorded a song of his.

Regarding calling Rythmik, for the OB/Dipole sub you want to call Danny Richie at GR Research. He and Brian Ding at Rythmik collaborated on the sub, but it’s Danny’s baby. He’ll tell you all about it; Brian Ding sells the DIY kit, but recommends his own sealed and ported boxed subs in preference to the OB/Dipole. You probably already know the G in your F12G refers to GR Research. The G woofer has a paper cone, the standard F12 an aluminum one. Danny feels the paper-cone woofer provides more resolution and a more natural timbre than does the aluminum.

@bdp24, yep Brian was nice enough to let me borrow a F12 and F12G for about a month.  I definitely preferred the G version and bought 2.
