The only etymology I could find is that the both first appeared in 1934.

I did scan Rice & Kellog's 1925 paper and the concept was not mentioned there - although they did build a three-way horn speaker at that time as one of their configurations.

Another reference, Briggs' survey of 1941 - did not use the term, so I would guess it was either not in wide use or only in use in the USA.
