I have a Denon AVR 2106 with Axiom M22 and Vp150. For sub Mirage S12. Everything sounds really good. My question is:

What cross over frequency is recommended? I am currently running with 80Hz.

TIA

Your correct, have your speakers set to small on the receiver, and a receiver crossover at 80hz. The autosetup of the Denon's will usually put your mains at large, I have 60's and still use the small setting. Also, make sure your crossover knob on the sub is either in bypass mode, or turned all the way clockwise to the highest setting, to get it out of the way of the receiver management.

take care,,,

80 works for a lot of us, but you should try100 and 60 just to hear the difference. Part of the fun!

I also have mine set to 80 Hz.

I've read that is where the THX recommends, but I don't know if that matter all that much.

As Bug posted, you might want to play around with the settings and see which one you like.
