Christian Groneberg (May 2005) I want to build a ribbon linesource. I've found information about a Swedish Ribbon Linesource Project and I want to built a more or less similar driver and do research about coupling it with a tractrix horn, so that I get I barrel-like uniform wavefront like the Beveridge Speakers have.

At first I want to build the driver, measure it and later on I want to find out what effect the horn has. In my oppinion, one can lower the frequency range of the driver from about 200Hz to 100Hz, which would be a nice takeover for a subwoofer. Also efficiency and max sound output of the driver could be ameliorated. I will tell you about the further developement of the project
