Nope, the one's he's talking about have Utah drivers: The P8R (IIRC) AlNiCo woofer and the RP-103 AlNiCo horn tweeter in a plywood bookshelf box with a shelf "vent". These systems had a couple of different Heathkit part numbers. EICO had a speaker that was similar if not identical.
I have a really ugly pair in the basement. They do sound good (although mine had been crassly re-woofered when I found them, but I have re-re-woofered 'em with EV LS8 fullranges).
