Hi Morzh,

The same technique was used in the Westinghouse designed Radiola 16, 17, 18, 33, etc., and, I guess, carried over to the (RCA) Victor- built Radiola 80, R7, R73, etc. I am sure that it was done as a manufacturing "efficiency". They likely either just had to hammer it down on the unassembled speaker, prior to adding the cone. They may have actually had a press that did it in one step.

One has to remember that some RCA radios introduced during the "Roaring 20s, particularly the Super VII, at $425.00, more than a very well-appointed Ford Model T! The coffin cabinet Radiola 60, in 1928 in the middle of the roaring 20s went for $140 without speaker. The Radiola 80, introduced during the Great Depression, much more radio than the Radiola 60, with console cabinet, electrodynamic speaker, push pull output, newly developed screen grid tubes, etc., went for $142.50 The R7A introduced in the throes of the great Depression, with on less tube than the Radiola 80, a table cabinet, but still with a similar speaker to the R80 and with Pentode 47 output tubes in push pull went for $72.50. I assume that the R73 was a similar price saving over the Radiola 60 or 80. This could only be done with economy of scale and more efficient methods of manufacture. Of course, the Depression caused manufacturers to tighten their belts drastically!
