Bought my 12+ August 2013, driver replaced once under warranty, driver started making noise at certain frequencies but otherwise still worked. Didn't bother me too much. Got up the other morning and it wouldn't power on, amp was dead, took it as a sign.
I live in Hawaii so the 12S costs the same as a PB2000Pro from Crutchfield. Watched and read whatever reviews I could find and read the comment sections and it seemed the 12S was the preferred sub of the two overall. Plus it seemed to have a better build quality based on weight.
After setup and some testing with music and a few movie scenes, it's good but doesn't quite reach the 12+ performance. I would've had to go with the PB3000R to do better. Didn't want to spend that much and I don't listen as loud anymore so the 12S is fine for my use.
Just wanted to give my 2 cents.
