The Genz neox 2x12T is already vertically stacked, weighs nothing, has inset one piece handles (no rattles) ,rubber rollers instead of rear feet (again no rattles) and adjustable tweeter. I actually have a Genz 1x12T too (I know, greedy) it's great but it's less than half the big one if you know what I mean. The Neox once trounced a pair of 1x12 purple chili cabs, it's put me off a pair of 12's ever since unless you don't feel like you want that extra bit of something that I'm sure exists.
