I know this thread is a bit old but I'll comment anyway.
I've had 4 of those set ups over the years and I wished I'd never given them away. At least the woofers. Yes, I gave them back to St. Vinney's, where I got the consoles from. About 5-7yrs ago our local St. Vinney's sold consoles for under $20 after tax. Then I guess they started looking at ebay asking prices and, well I don't buy there anymore.
IIRC the horns are 16ohm (@12ohm measured) and the woofers are 8ohm (@7.5ohm measured). There was / is a series? crossover that comes in the cabinet. You should use that if you still have it. I believe it attenuates the horn to match the woofers. Horns are about 6db+ more than the woofers, which are in the low 90's (again, IIRC).
My woofers (all 8ohm) had an Fs in the mid-50's IIRC and the Qts was fairly high, in and around 1.0.
Anyway, although not a fan of compression drivers / horns (maybe I haven't heard the right set up yet), I loved the woofers. I mated a pair of them up with all sorts of free or almost free stuff and they just sound nice.
I bet if you put the whole set up into a quick and dirty Visiton NoBox design it would sound so much better than the sum of the parts has a right to sound.
