Anyone tried the GNX128's?

If so, how are they? I've read good reviews on the GNX124's, but are these two subs identical except for the ohms?

you're not going to find much of a difference -- the thiele/small parameters may (probably actually) be off by a tick or two here or there, but in the grand scheme of things they're the same.
