I am not sure if Axiom has signature required. Mine were left by the door with both the M80 boxes in bits and both speakers damaged.
I will get to know soon..my replacement M80 has been shipped.
The axioms, at least for my EP500, was sig required, but there was/is some exception, I left a note that day with my tracking number, dated and signed and they left it. For all other deliveries ... W22s with W150 & QS4s, no sig required.
For W100, no sig required.
For this non-delivery ????????
