When I did a direct A/B comparison of the M22 + sub to the M60 at Axiom (this was v2) there was no real difference to me other than the sub playing lower than the tower. I suspect it would be the same with V3.

If you want to spend some 'just because' money, I would add a second sub or upgrade to the EP800 (or similar sub with greater low end extension than your current sub).
