hey bill-

why would a first order on a comp driver be out-- especially given the other things you were saying-- e.g. matching directivity and distortion capacities to the driver?

if you're crossing over a 1" driver to a 12" woof-- since you're already limited to what's possible with what you have-- you'd probably need to cross over pretty high, right? assuming to get the best characteristics out of your compression driver, you're going to need to knee it at about 1800hz-- so if you're already rolling off that high-- the driver will still roll off naturally too-- and a well chosen horn'll also help lift the load. in theory- you'd still be down at least 12 db by 450hz-- but the horn and driver'll run it down a lot faster to boot.

not to say you'd want to run 250 watts through it-- but it's not impossible to use a 6db/octave slope.. i think a lot of folks ask too much of their drivers!
