I purchased my AX3's in 1991 and they came with a "lifetime" warranty. I had all 6 drivers replaced in 2000 I believe and I paid shipping to send the drivers back.

When I traded them in on M80's during the 2010 anniversary, I was a bit disappointed that the warranty on new products had changed.

All is good so far with the M80's and I drive them quite hard with various amps.
