. . . They "MAY HAVE" been wired internally wrong. It happens!
Hi, All and each Axiom speakers pass a final performance test prior to being boxed which eliminates wrong internal wiring. A hard and severe shock while in transit might have caused internal damages. Because of the memory foam type used by Axiom for superior protection ; such an occurence might not be apparent. I agree that each M80 should be powered individually helping at determining if one of the two speakers was roughly handled durng transit.
