Current setup is Denon 4311 with M80's for R/C/L (Emotiva amp powers these), QS8's for side surround, and on wall M3 in the rear surround plus two subs. I want to get the Denon 6700 AVR and add Atmos speakers to the ceiling. I have two bedroom Axiom M2(?) bookshelf speakers that will go on a ledge 11 ft. up and 6 st. to the left of the listening position. I am looking for recommendation for 4 ceiling speakers? The M3 in-ceiling speakers seem to be the only Axiom product and seem more than what I need and a little pricey? Thanks.
