My understanding was that both response curves were pretty flat within the frequency range of the VP150, but outside that range (ie lower frequencies) the VP180 was still pretty flat while the VP150 was... um... less flat wink

Actually the FR curves do tell about a speakers SQ, if the FR is not linear or near flat then you can be assured of hearing a slightly (or worse) colored sound. The M3 is a perfect example, It has a different sound to it than the M22s and the M3's FR shows that difference, a dip in the lower midrange and a slightly elevated upper bass hump.

Having said that, FR curves are not the end all be all of how a speaker will sound, as has been mentioned, there are many other factors involved and the absolute worst factor is the listener's own preferences that can not be accounted for via a FR graph. But the FR graph will give you an idea of how much the basic speaker design is influencing what you are hearing.
