Tivoli Audio is an American electronics company based in Boston, Massachusetts, mainly making radios and other sound reproduction equipment. The company was started by Tom DeVesto. Tivoli Audio emphasizes a simple and functional design without redundant switches, knobs or lights. Henry Kloss designed several versions, including the PAL. Many types, including the Model One and Model Two, incorporate visual elements similar to Kloss' legendary KLH Model Eight table radio; most prominent is the vernier rotary tuning dial, which allows the user to carefully dial in a station without requiring excessively-steady hands. Tivoli Audio sells its products in the US, Canada, UK, Germany, and 30 other international countries.
