No, that's pretty wrong. The M60s should be crossed at 80 or less. Are you sure that all the drivers are working properly? (as in, stick your ear up to each one of them and make sure they're running). What often happens is that the straps between the upper and lower binding posts get disconnected, resulting in either no bass or no treble (depending on which set of binding posts the cables are hooked to. Sounds like you're missing the bass on the 60s.

Can you go into more detail on what's wrong?
