You said the flatpacks are 24-1/2" tall sitting on the 1" base. Where does that put the center of the tweeter?
14" from bottom of base, so, if a person sits these on top of a dual h-frame, the tweeter will be very close to the same height as the NX-Ottica. Remember how good the vertical off axis performance is ? Witheh NX-Ottica, yo ucan get up out of achair and not notice any change
here's a a couple pics of the cabinet with a trimmed up top edge on the baffle
A couple of the front and rear sides of the baffle itself
