Are you kidding?
The 10W1v2 is leaps and bounds better than the old w1. The W0 was a better driver than the W1. The W1v2 uses some basic linearity improvements in the motor learned during development of the W6v2 and W7. The W1v2 also incorporates the VRC (Vented Reinforcment Collar), Surround stress relief, Elevated frame cooling, Floating Cone Attach Method (FCAM), and more. You will not find another driver out there at this price point that offers 7 patents or patents pending.

The 10w1v2 will outperform the 10w1 in every way. It has more excursion, is more linear, works in a smaller enclosure, has better cooling capability, a rubber surround and more.
The lower distortion and higher excursion sell the W1v2 over W1 by themselves. The rest is a bonus, all for the same msrp as its predecessor.
