I have seen this opinion (VP180>>>VP150) expressed enough times that there must be truth to it, but I'm still a little confused why this is.

For the most part people respect the M22s, and I've heard it stated more than once, that M22s when properly integrated with a good sub come close to the sound of M80s (at least to a certain volume level, in reasonably-sized rooms).

The VP150 has a third 5.25" driver, yet many say that it sounds weak/thin on things like male vocals. I would think that if it set up with a sub and the right crossover settings, it should (like the M22) sound pretty good.

I do understand that the M22s are ported, and assume that this is the primary difference. The M22s are also spec'd to reach 25 Hz lower than the VP150. Can the extra driver and added efficiency not make up for bass-reflex design, even when properly integrated with a quality sub to cover everything below 85 Hz (or higher)?
