Full range for floorstanders, unless powered subs are used in them (even then some don't go below 30hz), is around the mid 30s and up from my experiences.

A wonderfull little system could be had with M22s and the EP400 sub. The M22s are a little less forward than the M80s and the EP400 is a great music sub that reaches below 30hz.

You could also look at M80s but install the resistors(available from Axiom) for the tweeters to cut down the treble.
