This explains it
As you can see in this article, the radio/phonograph was remote controled and had a "acoustical labyrinth". This was a massive advertizing ploy on their part. It was a great idea and it sold radios.
Here above it explains the acoustical labyrinth commercially.
The tag that would be on all Stromberg Carlson radio and phonographs with the labyrinth. However, I recall talking to an old radio man years ago who said it was just a bunch of nonsense. Just some cardboard. Not a folded horn that was in the orthophonic machines made by Victor and later RCA.
As you can see in this picture below, here is one of the horns unwrapped...and I was surprised to see it is all cardboard.
So did it work? I guess it did to a degree. In fact it was one of the many horn types of radios that have come onto the market leading up to the Bose Wave Radio and speakers which are basically folded horns, not too unlike the orthophonic and to a degree the acoustical labyrinth of the 1930's. Just smaller in size.
It is interesting to note that the orthophonic of the 1920's and the acoustical labyrinth of the 1930's and 40's were noted for the bass they produced, and if we look at the modern follower the Bose Wave Radio..it too is famous for its bass, and for a labyrinth of design that re-enforces the bass and treble it reproduces like it's fore bearers.
