Eminent Technology is an American audio electronics company based in Florida, established in 1983 by Bruce Thigpen. Their first product was an air bearing straight-line tracking tonearm for phonograph playback, and was the first implementation of a captured air bearing for tonearm use.[citation needed] It was followed by a more advanced version of the tonearm.
In 1985 the company began developing planar magnetic loudspeakers and in 1987 introduced the world's first full-range push-pull[clarification needed] planar magnetic loudspeaker, the LFT-3. Another of the company's products is the Thigpen Rotary Woofer. Typical subwoofer products are inefficient at producing desired sound pressure levels at frequencies below 20 Hz,[1] but the TRW is designed to cover the range down to 1 Hz of the sound spectrum.[2] (The technical principle would allow even zero Hz.[3])
In the 90s Eminent Technology developed a smaller planar transducer for automotive applications. This was adapted for computer speakers as the LFT-11, a multimedia speaker system,[4] The company licensed the technology to Sonigistix and it appeared in Monsoon and other brands.[5]
Currently five US patents have been granted to Eminent Technology products. The company manufactures most of its products at its own facility in Tallahassee, Florida.
