Scored some PAS speakers out of curiosity. Very surprised!

I saw these locally and a good old Altec 604 came to mind. I purchased them for less than what the wood probably cost for the cabinets. They are SUPER heavy cabinets by the way. I made some wire jumpers, hooked them up and will be doing some listening tonight but from the little that have already heard they are REALLY nice. Nice enough I will be opening the cabinets up tomorrow and seeing what's inside and might build some crossovers for them to hopefully really get them singing (though they sound pretty great as is). There isn't much information for these particular models though and I would love to get some specs on this actual speaker. I know they are very efficient and I am using 300B amps that were built specifically to pair with Altecs and they sound great so I am guessing they have to be somewhere in the 99-100dbi efficiency from the sound levels I am getting from them.
I have read that in the 1980s, Professional Audio Systems (PAS), using Time Alignment technology from Ed Long, sold the popular SW series of compact stage wedges, offered with a 12- or 15-inch woofer, (these are 15") and having a projecting high-frequency horn as in the 604 but that is about all the information I could find that seemed legitimate. The seller said these had been in his church for years.
