If your usage is...

Movies only: QS4s.

Music only: M2s.

Mix-n-match? QS4s.

The QS line is, IMO, the strongest speakers in Axiom's lineup. I don't mean "powerful" (well, duh), but they are phenomenal for environmental effects and diffusion of sound - but precise enough when need be to do pinpoint location work, too.

Great speakers.
