The voicing of all Axioms have a similar timbre.
It mainly is dependant on Atmos which states all mono pole speakers in such systems, room size and your wants.
I've tried M3 and M22 as surround both of which were great. Though in 5.1 or7.1 the Q series is something else. Also in DTSX the Qs are awesome.
With the HP woofers of the LFR1100 you may like the HP woofer of the Qs10 though with a decent big subwoofer 500 and larger the HP duties would go to the sub.
