I remember hearing those Klipsch speakers 3-4 months ago and they never sruck me as lacking in bass. Could be that people end up remembering the "Klipsch Highs" after auditioning and tend to forget the bass as an afterthought. Of the dozen or so speakers I auditioned before buying Axioms, I don't recall any of them going as deep as the M80s, though(inc. P'digm Monitor/Studio, Monitor Aud RS series, Klipsch, Energy, PSB, Polk, Mission, JBL ect).

Half of communication is listening. You can't listen with your mouth.
