Best MUSICAL subwoofer for Maxx 2's quality sound?


I posted this under the "speakers" forum, rather than "home theater" for a reason.

Looking to either buy another M&K MX 5000 subwoofer to go stereo pair setup....or, maybe a whole different subwoofer setup.

Running Wilson Audio Maxx 2's, and want to supplement the very low end (below 80 Hz) musically and very powerfully. (Maxx 2's are powered by 2 McIntosh 1201 monoblocks).

Suggestions? Just add another MX 5000, or change? If so, to what?

Thanks, in advance.

Ican't find EITHER of the two above mentioned references by Bob and Ras. Any help?
Excuse me, but I have to ask. You have $50k ($28k used) speakers AND THEY NEED A SUB?

I do not understand some things, and people, for sure.
Rnm4: It doesn't matter how full range a speaker is when placed ideally for imaging (away from walls) you can lose bass reinforcement. You can also end up with the main speakers in a bass null related to the seating position. So using actively crossed over subwoofers in the best location (to prevent nulls or peaks) for subwoofers you can achieve an ideal balance.
