Richard Sequerra was born in 1929 and raised in various parts of the US by his mother, who worked for the Department of State. By the time he was 20, he had launched a freelance career that has since spanned a wide range of technologies. During a stint at Marantz in the 1960s, he worked with Sidney Smith on that firm's famed Marantz 10B tuner, which was sold from 1964 through 1970. Subsequent products have included the Sequerra 1 tuner and the Metronome 7 loudspeaker, originally produced by Sequerra's firm Pyramid and now hand-assembled by its creator, who offers the most recent version via his website
, for less than half what it cost through retail channels when Sam Tellig praised it in the July 2007 Stereophile
. Sequerra's newest transducersa self-amplified nearfield speaker and matching subwoofer designed for Internet music listeningremain in prototype form; he hopes to sell or license the designs rather than manufacture and market them himself.
