Eminent Technology was established in 1983 to create innovative products in the audio field. Eminent Technology's first product was a air bearing straight line tracking tonearm for phonograph playback. This was the first implementation of a captured air bearing for tonearm use. Eminent Technology's second product, dubbed the ET-2, was a more advanced version of the captured air bearing tonearm concept and it went on to become the most successful selling high-end tonearm. In 1985 Eminent Technology began developing planar magnetic loudspeakers and in 1987 introduced the worlds first full range push-pull planar magnetic loudspeaker, the LFT-3. Since that time Eminent Technology has continued to advance its loudspeaker technology and has introduced a number of new models including the first planar magnetic computer multimedia speaker.

Eminent Technology manufactures most of its products at its own facility. It also manufactures Edison Price Music Post, a five way binding post, and is a OEM supplier to a number of other audio companies. Four U.S. patents have been granted to Eminent Technology products.
