Testing various 1920's horn and cone speakers to find out how they sound with a Hi Fi input.
Very interesting results, particularly with "direct injection" and the cone speakers are very good, maybe should be reinvented. Units were feed from a solid state amp with a matching transformer from eight ohms to a few thousand ohms as these speakers were designed to run directly in the HT plate circuit.
Great clip, Big girls don't cry.

If you want to know how a 1927 wireless sounds on a modern speaker, actually very Fi.
