OK, so... I won't even try to front. I'm trying to do something for nothing, basically. :D
Got a pair of C36 cabinets, empty, that were given to me a while back. Also, now have a pair of 2220J woofers (thanks JJ!).... close enough to 130As, for government work.
Now, what I need: some sort of horn/driver that will "sub in" for the LE175 and horn/lens. However, since the rest of this project has cost 0 dollars out of pocket so far, I'm looking to try to do this, without spending much $...
What I was thinking of: as for a horn flare, this has been recommended to me: MCM Electronics carries a short, conical 90-degree dispersion horn... check it out:

I think this should be able to bolt into the hole in the C36 baffle... the hole is between 5 1/2 and 6" diameter.
This, with something to make a decent substitute for the LE175 (of course, a 2425J or the like, would be ideal, but again, that'd be $$), might just do it. Keep in mind, that I DO have access, to a very sophisticated measurement apparatus, and am not averse to building the crossover, to flatten out the response a bit up top, of whatever I get.
So, what I'm basically asking: Anyone know of a GOOD low-buck option for a HF driver, at least until I can afford to (or get lucky and find cheap) get a 2425 or its ilk? Just something I can safely take down to the 1200 Hz crossover point... or even down to 2400 Hz, if 1200 ain't gonna cut it. What I would want, is something that might have the "general character" of the LE175 or 2425... I'm even thinking, the local PA repair place near here has some old 2"-diaprhagm EV drivers... it doesn't have to be perfect, just fixable/usable.
In short, this is kinda a learning experience for me... to get used to dealing with more horn-loaded mid-HF drivers and such. If I can get it to sound good, so much the better!
Thanks for any suggestions...

Gordon.
