Well, not only is the driver motor upgraded, but I'm guessing that the biggest improvement comes from the increased box size. It would appear that Velo is moving away from an aesthetics driven solution to a performance driven one. It's easy to do if you increase the box size. Trust me, they certainly haven't "checkmated" JL Audio by any stretch of the imagination. Copied them, perhaps, but not "checkmated". That's nothing more than hype, especially without any testing.
