Arthur Janszen was granted U.S. patent 2,631,196 in 1953 for an electrostatic loudspeaker. He had worked in the Navy to develop a low-distortion, high-frequency source for targeting torpedoes. After the war, he developed manufacturing technique for electrostatic speakers, to be used with conventional cone woofers, known as electrostatic hybrids.
Magnepan has used several different technologies in constructing their magnetostatic speakers.All Magnepan speakers are based on flexible ferrite magnet strips (like refrigerator magnets), 0.060" (1.5 mm) thick, typically cut to either 1/4" (6 mm) wide (mid-bass) or 1/8" (3 mm) wide (tweeters) and more or less the length of the speaker.
