why not use the pre-outs on the 1060 to provide a signal to a subwoofer, just use the lowpass filter in the subs amp.... let the crossover in the amp do its job.
This is essentially what i am doing with my processor.. My balanced inputs for my L/R speakers go to my amps.. For my L/R subs, i am using the RCA output to provide a signal to the subs. i am not using the cross over in the processor at all.
Also keep in mind, you can get a "real wood" finish, this way you can get a finish that your wife may find more acceptable.
I am no expert, but the M22's seem kind of small for that size of a room.. Maybe Brent or JC will give their input, also do not hesitate to call axiom, both Brent and JC are great guys and the company philosophy is to not over sell. They strive to get you the "correct" product, many people have shared their experience about being talked down in size.
Good luck with your decision.
