I'm sort of in agreement that while the M22's are highly detailed, they also sound a bit thin. I've got a sub paired with my M22s and found it hard to blend it in to make it not noticeable. If it's crossed over more than 70Hz, it sounds boomy and seems to separate itself, even with the sub's volume turned down. Currently, I have it set at 65Hz with the volume about a third of the way up. I'm satisfied with the sound, but I can still tell a subwoofer is involved, whereas my M60s/sub combo blends together perfectly. Perhaps, it's my Yamaha sub which simply might not be a good match with the M22s.
I also own Ascend CBM-170s which I think have a fuller sound, but they aren't quite as detailed as the M22s. They also have a slight different sound signature than the Axioms. Currently, I'm using the M22/sub combo, but haven't given up on the Ascends yet. But, since I like the Axiom sound so much, I also can't help wondering the if M3s could actually offer the best of both worlds.
