I'm fortunate to have 3 separate quality systems - 1 HT & 2 Audio Only.

I set up the HT on Audyssey for movies & then leave it alone. The only music that I play on it is live concert DVD/BDs that generally do not come across as pristine as studio recordings; however, it sounds just fine with the yahoos in the crowd coming across too loud & clear in the sound field behind & around me.

My 2 Audio Only systems have no capability of automatic EQ so I take what the room gives me.

Getting back to the original premise of this thread about upgrading the twin drivers in the M22, if Axiom produced HP versions & new cross overs, I wouldn't bother 'upgrading' because I find that the present M22s do the job just fine when paired with subs. If subs weren't involved, it might be a different story....
