Hand crafted in Conifer, Colorado.
Roger Sanders has been at this for 40 years. His first published article on Electrostatic Speakers was in 1974, followed by another on amplifiers to drive ESL's in 1976.
His contribution to audio include the invention of the curved, free-standing, electrostatic loudspeaker driver; the development of extremely compact transmission line woofer systems; integration of electrostatic speakers and transmission line woofer systems; and, several "how to" construction articles in "The Audio Amateur" and "Speaker Builder" magazines.
Throughout all this time, he has been perfecting the hybrid electrostatic loudspeaker, as well as designing amplifiers to effortlessly drive them to maximum effect.
