I would think that if you got the M2 they are far more flat but fall off with the lower frequency tones. The M3 have the ability to carry the lower frequencies, but will get a bit more muddy in the mid tones if you push the volume. But as you said. You are playing these not at high volume, so I doubt that you would ever exceed the 6.5" drivers ability to create the mid tones, but gain in the surface area to make the lower tones.

just my take on it. I have the M3 but have not tried the M2 so I have no point of reference.
