I've never had the Qs8, But got in on early Qs10. they are fantastic. Use mine as side surround, in a 5.2.2 Atmos. DTSX set up. 1.5 to 2 feet above seated ear.
M80 VP160 powered by a ADA1250, Qs10 side M22 as front height.
Suspect 4 Q series would probably be more effective unless your taking the plunge to ATMOS. To which have read strong recommendations for multi pole speakers as width, for best envelopment in such systems.{7.2.4 9.2.2} Haven't tried my Qs in such placement yet. So far terrific as sides.
With your M100 being in the HP line the match might be better.
