Eminent Technology LFT-16 loudspeaker
There is much to admire and to enjoy in this idiosyncratically charming hybrid loudspeaker. Eminent Technology has been around for about 25 years. Founder Bruce Thigpen was a pioneer in air-bearing technology, and ET's first product was a well-regarded air-bearing tonearm. The company later developed and was awarded patents for its Linear Field Transducers (LFTs): <A HREF="http://www.stereophile.com/floorloudspeakers/308et">push-pull loudspeaker panels</A> that operate on the magnetic rather than the electrostatic principle. Arraying magnets both front and rear of the plastic-membrane diaphragm eliminates a problem inherent in many planar-magnetic designs: as excursion increases, the magnetic restorative force diminishes. As can be expected, this technology is not efficient at reproducing bass, so most such speakers have been hybrids.
