I talked to Axiom on the phone yesterday and was told it's the same driver.

We also talked about swapping out the older 350 driver for the new one and although it can be done it isn't cost effective.

I paid $300Cdn for my 350 (used) and I would still be better off to sell it and buy a new 350 with the newer driver. Btw the new driver does play a little lower as well.
