So I’ve got that the M2s will not be great.
M2’s with sub, IMO, should be fine.
things to consider…
- in testing I’ve haven’t noticed any loss in fidelity going to the M3’s
- your AVR is sending anything a surround can’t produce to the subs
- directional content starts around 80Hz .. M2’s should not be a problem
- When engrossed watching a movie you’re not critical listening. Especially to surrounds!
- You can always trade up (M2->M3->M5) for no cost.
That said … I really like My QS10s in the family room. I should try swapping in QS8 (from the bedroom) and see if I notice a big difference.
The family room is 5.1 M2/VP150/EP500 with QS10 rears
