Not taking a stand either way, I would make two points for consideration.

One: No one is going to buy a Ninja M22 crossover UNLESS Axiom has first sold a pair of M22s.

Two: Though I've not heard a Ninja M22 crossover, I have no doubt that it creates a "difference" in the sound of the speaker. However, "better" is a subjective conclusion. Some may find a Ninjad M22 more to their liking, others may not. IMHO, neither position can, or should, be considered "wrong."
