hi geekstar,

still kicking tires here - my friend who can
run the sims is still busy finishing work for
his masters degree...

eurodyn's very handsome - (not sure if there
are klangfilmists here) - square format interesting.
how do they image compared with round tractrix?
do they also throw a tight image with a small
hotspot?

oval makes sense for me as it seems to present
fewer discontinuities in flare, easier to blend an
oval into a circle than a rectangle.

also, should the calc for the flare start from
the exit of the compression driver or include
the 'root' of the flare back to the phase plug?

cheers,

a
