Think these are pretty rare. Doing some research on unique vintage theater sound systems and came across blueprints for a Westrex T5208 baffle and horn assembly. Looks like 4/9/1953 is the date on the print. Two 15's (18's ???) one directly above the other - into some type of exponential flared horn (horizontally). The upper and lower surfaces - unlike say an Altec 210 VOTT cabinet - are NOT parallel. They look to be at angles of .....oh, about 20 degrees from horizontal (in a side view).

Anyone ever heard one of these systems or seen one? With the left, right, upper and lower baffles, it seems to be a fairly large speaker.


Thanks..........
