I am in the process of assembling a 3-way PA system intended for events of 50-150 people. As someone who’s relatively new to this (background being more DJing and promoting), I’ve still got plenty to learn, hopefully through forums like diyAudio.
Specifically, I’m looking to get advice or assistance with amp selection, driver selection/installation, and rewiring for two vintage JBL 4560 cabinets (which need 15s) and new tweeters (see attached). I had purchased both secondhand last spring from the original owner who had them custom built by Banquox Sound owner, Henry Kreindler. These builds are to complement two nearly finished dual-loaded JBL 218s subs, which are pending restoration and aesthetic detailing and will handle the low ends of the 3-way system.

Hank got good results with ElectroVoice 15Ls in 4560s used as mids on top of big ol' woofers. Cross 'em over at 150 Hz & 1200 Hz, get yerself a Double Fat Boy & chips-chili, and rock all night. For that vintage experience drive with Yamaha P-2200s, and make sure to power them up at least a half hour before the gig as they tend to sound a bit glassy when cold but sweeten nicely after they warm up.
By the way, there's no attached to (see attached).
One more thing, when I was in the business [1] JBL drivers had a gotcha: a positive voltage on the red terminal made the cone move inward, as opposed to the rest of the world where positive on red moved the cone outward. That would be relevant in the crossover region.
