I have also thought a vertical system works best, well it is proven hence the old column PAs (WEM). I have fancied having a split 4x12 angled cab down the middle, ported so the you can alter the frequency like the old trace cab holes. They would also have tapping options for impedance changes So these can be used side by side virtically either side of the drummer. Or altered by porting to lay on their side so the angle projects the sound across the stage and one cab becomes the bass and the other the top. If you are into bi amping as i was once.
Just a thought, but go find one of those EA cabs if thats your bag.
