Best MUSICAL subwoofer for Maxx 2's quality sound?

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.

For what its worth I wonder that the issue with base may not be a function of your amplifier. The Mac 1201, while a great amp, has if I recall an autotransformer. A chap I know has the exact same set up and complained to me about not having enough base. Though i am not terribly knowledgable about this, I spoke with a friend of mine who is very familiar with the area and he was concerned that the amp would not work well with the type of load a maxx 2 presents. This is not said to stir up angst or anger but just an observation. The maxx 2 are great by the way. Good luck
