The Eminent Technology LFT-8b, ETI's first hybrid loudspeaker using the highly acclaimed Linear Field Planar Magnetic Transducers combined with a low Q 8" woofer in a sealed inclosure.
The magnetic drive principle developed by Eminent Technology for the LFT speaker series is unique to the industry. As the diaphragm of the speaker moves between the magnets following an audio signal, the magnetic field remains constant. In a sense, it is the magnetic equivalent of a push-pull electrostatic loudspeaker, differing in that it requires no step-up transformer or bias voltage and that the audio signal is applied directly to the diaphragm.
In order to obtain a uniform driving force over the entire surface area of the diaphragm, a low mass foil/mylar diaphragm is used with conductor traces etched (like a circuit board) with high resolution. The large surface area of the midrange driver gives excellent power handling capacity. A thin lightweight diaphragm is utilized for the high frequency driver.
The LFT-8b minimum recommended amplifier is 50 watts/channel. The maximum recommended power is 200 watts/channel. The speaker is moderately efficient and its impedance averages 8 ohms.
The low frequency woofer was carefully designed to blend seamlessly with the mid-range and high-frequency drivers. The design uses a very low crossover frequency (180Hz) between the woofer and midrange. The woofer has a very high complince and operates with a near critically damped system Q of .58. This tuning insures excellent transient response.
The panels are attached to a rigid steel frame to prevent resonances. The woofer is mounted in a rigidly braced enclosure.
The LFT-8b is biampable and uses the Edison Price Music Post. The standard finish is oak with black grills (shown), optional finishes are available for an additional charge. The retail price is $1999 per pair.
