a 10W3v2. It was no longer listed in JL literature when I bought it. The store I bought it from called JL about it to see if the could get one. They told me that JL took the mold down from some storage shelf and made a few more. Sounds kind of like BS to me, but I was really happy to get it, even at full price.
I'd tend to use the 10W3v3 for a replacement driver.
