KEF crafts the Muon from 6 mm sheets of aluminum using a process called superforming; no metal sculpture in New York’s Museum of Modern Art is more meticulously fabricated. Its curved shape, thick aluminum walls, and heavy internal bracing give the 253-pound, 78.8-inch-tall Muon a rigidity that the George Washington Bridge might envy. This rigidity prevents the speaker cabinet from vibrating in sympathy with the sound waves, which would mar the Muon’s sound. The speaker’s curves eliminate edges that can reflect sound, so all you hear are the waves coming directly from its woofers and tweeters.
