I have M80's and love the sound quality.
I will be more than happy to take the M22's off of your hands.
I'm just kidding of course.
Seriously, The M80's are more than enough. I don't know how the M22's would sound as "presence" speakers as I have never liked the way Yamaha does their surround sound modes (my personal experience in the past). Also, you may need to research the Yamaha to see if it can handle a 4-Ohm load effectively. Does your Yamaha do phantom speakers for the sides? If so, this may be another option. I wouldn’t daisy chain the two you might be asking for trouble. If you had a good amp, you might be able to use the m22’s as a huge center channel (using two channels of an amp and a couple of Y adaptors).
Have fun!
