I'm looking for quality sound, not volume. My understanding was the M80's would deliver the highest quality sound, even at low volume, but that the M60 required more volume to sound almost as good. The M22's are missing a midrange speaker and therefore someone said that it was also lower in midrange quality.

But, my car is giving me problems at the moment. Replaced battery. Now it sounds like it's probably the starter. Will have to spend some of my speaker money on it go get it fixed and postpone my M80 purchase at the moment. Grrr. Always something.
