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.

My dedicated listening room is only 11 x 18 and I have two pairs of bookshelf’s I alternate between, Harbeth 30.1s and Revel M126be. If I had a bigger space I would have gone for the new T7i or T9i which, frankly are better RELs.
