I think a Birdhaus 68 would make a great cab!
Four 8's vertical on front + one 8 on each side.
Maybe 2 48's would be better!
Flip the top one upside down.
I would like to try that very thing; my thinking was that way the side woofers would be closer together (better coupling?).
In keeping with my “lateral overhang” aesthetic such a stack would have to have a pair of CS800s on top; each bridged and driving one of the cabinets.
