Kloss, as you know this was the Altec Lansing loudspeaker product line circa 1941 or 1942. I have stood in that spot in recent years and photographed the building; it has not even been painted inside since those days. The white square which looks like a piece of paper on the floor is actually a patch to the concrete slab; it has blended in nicely in the 70 years since the picture was taken. Note the third system from the front: it is a small 800Hz. theatre system utilizing Iconic components. It would have to be considered an A7 ancestor, though I've never seen one of these turn up in the modern era.

Yeah, that thing is very cool. Looks like a miniaturized WE front horn baffle but surely it is sealed box on the rear rather than open back. Always wanted to know more about that one.
I have poor, retouched front and rear photos of this system in an old Altec service manual. It was called the 18-W-8 system, and unusually for the era used permanent magnet drivers. The 901 h.f. driver was used with the H-808 tar filled (Iconic) horn. A 1565 15" woofer was mounted on the H-24 horn baffle, whose dimensions are listed as 84" wide by 60" high by 18 3/4" deep. The woofer just hung off the back with no rear enclosure. So it was just a short, straight sided front horn terminating in in the flat baffle. Maybe it didn't sound too bad, though it didn't stay in the line for long. The 1565 woofer was described as having efficiency down 4 dB. compared to the 415 field coil unit. Yeah, ain't it the truth!
That is wild! I didn't know that the open baffle front horn scheme survived the WE wide range era!! PM, no less!
The above-mentioned link is the only pic I ever saw of that exotic system. Love to hear one but this will probably never come to pass...
Sure is a amazing collection.
