Hi Dave, welcome.
Too many stats!! Really, the only way to tell is to listen.
While doing a search here on Wharfedale might turn up something useful, this is the Axiom board, so we're highly likely to tell you how wonderful the M22 and M3 (and other Axiom models) are.
I don't know upon what basis you can conclude that the Wharfedales have "deeper bass". WHile the product brochure I pulled up rated them to 45Hz, it did NOT say under what tolerances. They might be down -10db at that frequency for all I know.
It is unlikely that the impedance will be an issue with your Yammy, so don't worry about the Ohms difference.
People who have them LOVE the M22's.
