Wide-Dispersion Surround Channel Performance
MartinLogan's EM-FX2 surround speaker features dual Folded Motion XT tweeters in a wide-dispersion array ideally suited for surround channel applications. A single 6.5" doped fiber-cone woofer provides powerful low-frequency extension. Available in either black or white, the EM-FX2 is designed to corner mount, wall mount, or angle-wall mount for versatile surround sound placement in any room.
Folded Motion XT Tweeter
The EM-FX2 has dual 1.25" × 2.4" Folded Motion Transducers with a 4.5" × 2.75" diaphragm.
MartinLogan's new larger, low distortion Folded Motion XT tweeter boasts a radiating surface 40% larger than those found in the company's award-winning Motion Series products. The XT uses thin film transducer technology which draws from the company's acclaimed electrostatic driver designs.
MartinLogan's exclusive and highly innovative Folded Motion Tweeter helps gives the EM-FX2 its fantastically realistic highs. Lightning fast transient response, combined with a large surface area (eight-times that of a typical 1" dome tweeter) creates clear, highly dynamic, and precise sound.
The Folded Motion Tweeter works by moving air (which creates sound) perpendicular to the folded ridges of the diaphragm, similar to how an accordion works. This extremely low mass diaphragm 'squeezes' air and requires almost 90 percent less excursion than the typical 1" dome tweeter, which drastically minimizes distortion while providing a lighting fast response time. The increased surface area also provides a wide, yet controlled sound dispersion to create a realistic and carefully etched sound stage.
The EM-FX2 also features convenient push-style speaker terminals, adapted from MartinLogan's award-winning Motion Series, with curved inserts that help guide speaker wire effortlessly into place. The rubber end caps on the terminal are also removable for the use of banana plugs instead of bare wire. So simple, you'll actually enjoy hooking up these speakers.
The EM-FX2 has a frequency response of 55–25,000 Hz ±3 dB, sensitivity of 93 dB @ 2.83 volts / meter, nominal impedance of 5 ohms (compatible with 4, 6 or 8 ohm rated amplifiers), 160-degrees x 30-degrees dispersion, and a recommended amplifier power of 20 - 200 watts per channel. It measures 14.9" high, 184" wide, and 6.8" deep, and weighs 16 lbs.
