Symdex was not in business very long, the Sigma loudspeaker was the main product, though they also built another two way and a subwoofer. The designer, in his first design job I believe, was none other than the great Kevin Voecks. Voecks went on to design for Mirage using the Canadian Research facility, with Floyd Toole, and then went on to design for Snell, after Peter Snell passed away so tragically. Currently, he designs the Revel line for Madrigal.
The Sigma was a very fast two way. There was a review in The Audio Critic sometime in the early 80s.
