Sundown x12 isn't worth the price imo, and I've owned both rev1 and rev2 versions. I actually owned my Rev 2 and gcon at the same time and was swapping them around doing some testing. The only thing the gcon didn't do better was lows, but it wasn't enough difference to justify the price difference. OP the incriminator LI 12's would be a good alternative, as well as ascendant audio havoc 12's...but you can't go wrong with the icons either.
