I've opened many speakers and operated on them. I've replaced the caps and resistors in the cross overs, added damping, changed the wiring.
Anyway, everytime I unscrew a driver from the MDF cabinet and then screw it back together, I think that the contact between the screw and the MDF is degrading. I wonder whether whatever improvement I hope for from my tinkering is offset by the sonic consequences of the inevitable relaxation of the connection between the screws and the MDF.
All this to say, quality control is important. The fewer times anyone unscrews these things, the better. Some folks don't mind taking things apart. But all of us purchased finished products, not kits.
My experience with Axiom quality control is excellent. I've never received a defective product from Axiom. They obviously take quality control seriously. Every once in a while, someone on the line lets something get by them. I don't blame Axiom for trying to enlist the customer in the cause of repairing a defect, but ultimately, I'm sure Axiom will stand by their product.
Good luck with your new speakers. Please let us know how you like them once they're sorted out.
