Henry Kloss (1929, Altoona, PA–January 31, 2002, Cambridge, MA) was a prominent audio engineer and businessman who helped advance high fidelity loudspeaker and radio receiver technology beginning in the 1950s. Kloss was a student in physics at Massachusetts Institute of Technology (class of 1953), but never received a degree. He was responsible for a number of innovations, including the acoustic suspension loudspeaker and the high fidelity cassette deck. In 2000, Kloss was one of the first inductees into the Consumer Electronics Association's Hall of Fame. He earned an Emmy Award for his development of a projection television system, the Advent Video Beam 1000.

Kloss briefly went into retirement, but soon found himself co-founding another company, Tivoli Audio, with long-time associate and former Cambridge SoundWorks co-founder Tom DeVesto. There, he made the Model One (mono) and Model Two (stereo) table radios using MOSFET technology to increase selectivity; they have elements similar in appearance to his legendary KLH Model Eight radio mentioned earlier. The high-quality tuner combined with a good speaker arrangement led some reviewers to call these modern radios "Bose killers." However, the Cambridge SoundWorks Model 88 had used some similar technology, leading to a lawsuit between Cambridge and Tivoli Audio.
