The M5HP will be so much better! The M3 bass and mid-range blows; the M22 blows too. Everyone who owns an M3 or an M22 ought to do their ears-brain system a favor and upgrade.
Ouch. Are you talking about the bookshelves m3's ? Or onwalls? The bookshevles with the right amp can put out a nice bit of bass. The onwalls.... no bass and definitely sub.
