Early models came with a lifetime warranty, but as has been indicated there might not be any stock of the old drivers around. In speaking with the parts folks when we were onsite last Sept., they had no stock of some AX line parts. My AX3's needed parts, and they shipped me a complete new set of drivers.

They have a set of AX3's, as mine stayed behind after the 30th party...and M80's came home with me!

Well, they were shipped afterwards, but the sentiment holds!
