You're obsessing over minutiae.

will they fill the room with shrill and sharp treble that will make the experience more uncomfortable than accomodating?


They're going to fill the room with whatever source you feed them. Axiom speakers don't degrade perfectly nice source material into "shrill".

Get an audition. Or, get the M22's and audition them with a good sub. If you don't like the M22's, it won't cost very much to return them. If you do like them, Axiom will probably accommodate your upgrade gratis during the trial period.

Dude.
