Will Rockwell’s Colossus, a passive audio amplifier

The Colossus is a Steampunk creation, a marriage of 19th and 21st century technology. It broadcasts through an antique brass gramophone horn, yet is driven by an Iphone or comparable smart phone. The sound from the phone travels through a tube into the brass bell. In this test we hear Enrico Caruso from a 1904 recording on YouTube. My assistant Kimmy is in attendance.
