So that original *pic* which look a bit slanted is an
accuirate representation.

I'm seeing just the 4 inchers and the tweets but no details of
the casework. Well, I guess I'll have to wait for publication.
I would guess from your other designs that the line array would
focus the energy from the backwave either up or to the sides in
a mirror image and in a v-shape.

The samples... or proof of concept I guess... that I have are
just the 4 inchers at the top end of a baffle with overall height
of 48 inches. The stand for them is jimmy rigged.
