The M22's+sub are almost equal to M80s+sub, but as Alan mentioned the M80s do have a bit smoother sound to them and better mid/upper bass. This extra mid/upper bass was what made me go with the M80s over the M60s and M22s as my main listening speaker. The M60s+sub sound nearly identical to M22+sub, IMO. The 60's do not seem to add as much mid/upper bass to the equation as the M80s do, but they do offer more than the M22+sub, but this is all only based on A/B testing. I highly doubt anyone could tell much difference with out A/B tests. YMMV.
