Which subwoofers have at least a 20k input impedance as required for ARC preamp

The long title is the question. Very hard to find sub specs. Thanks for any information.

I recently upgraded my pre to Ref6 and now considering the REL 212/SE. I used to own a pair of B1’s and IMO, REL integrates much better than any other sub in a 2 channel system. The plan is to drive 212/SE using its high level input from speaker output terminals of my GS150 amp.
