I'm starting to research my winter loudspeaker project, and I've decided on a two-way high efficiency design. The woofer will be a 15" unit (TBD), and the compression driver will be a JBL 2445H/J or 2446H/J, most likely mated to a JBL 2380 or 2382 horn.

I'd like to cross the system at 500-600 Hz, and I'm looking for suggestions for a passive crossover for this compression driver / horn combo. I realize I will have to apply some EQ to obtain flat response up to 20KHz.

So my questions are:

Are there any commercial JBL products which utilize this driver / horn combination at this crossover frequency?

If so, where can I obtain the schematic for the crossover?

If not, has anyone [ Wayne, this means you :-) ] got any ideas where I could start with this design?

Thanks in advance,

Mikey
