These horns are pretty to look at and elicit the "that's really neat" response when the grill is removed, but I have to wonder just how scientific the designs were. The shape of the horn varies by model, with the oval flaring up vertically rather dramatically in those models that could take the larger horn (like the Cortez and the Hampton). The wooden horn of the Brunswick Exponential series machines hews to their earlier Ultona-era designs rather closely-a wooden throat extends down from the tonearm base into an oval molded wood horn. Brunswick's Exponential offerings were in competition to Victor's Orthophonic and Columbia's Viva-Tonal machines, in that the systems of reproducing the music from records were based (however loosely or otherwise) on the research done at the Bell Labs. The Cortez model uses the largest horn, and seems to be the more sought after of the Exponential series.Īs far as the licensing, yes, that is my understanding. While I personally like Brunswick machines, and feel that they are well-built and a bit under-appreciated, I'll leave it up to other members to rate the desirability factor. Not sure if these were considered "exponential" models or not. ![]() Then too, there were suitcase portables with spring-driven motors that were called Panatropes as well. and were usually powered with spring-driven motors, but electric motor models also offered. The Exponential models were housed in sturdy cabinetry that frequently used model names like Madrid, Cortez, etc. Most Exponential models date from mid to late 1920s I believe the Panatrope name lived on in later radio-phono combinations from the 1930s-40s. In this case, all-electric refers not only to the motor but also the use of a cone speaker and amp. ![]() This Exponential type is the acoustic counterpart to their all-electric models, which Brunswick introduced after they had launched the all-electric Panatropes in 1925. ![]() The Brunswick Panatrope line was designed to play their new (in 1925) electrically recorded discs. Not to relate the entire company history, the Brunswick-Balke-Collendar company was a long established company that entered the phonograph business in the post- WW I years.
