The new version has a 6" "multi-fiber" driver vs the older 6.5" driver.
They've also switched to a titanium tweeter instead of a soft dome, and say that the HF response now goes up to 51kHz. I'm sure all the dogs on my block will appreciate that.

I know I've seen other posts where Barefoot has disparaged the use of metal alloys in drivers. Has anyone heard and been able to comare these two models side by side?
