MartinLogan ElectroMotion FX2 Surround Speakers

The MartinLogan ElectroMotion FX2 is a dedicated high-performance surround speaker engineered for wide, immersive coverage in premium home theater systems. It combines dual Folded Motion XT tweeters in a wide-dispersion array with a 6.5-inch woofer, producing 160° horizontal dispersion, 93 dB sensitivity, and frequency response extending from 55 Hz to 25 kHz ±3 dB. MartinLogan, Ltd.

Designed specifically for surround-channel duty, the ElectroMotion FX2 can be wall mounted, corner mounted, or angle-wall mounted, allowing it to deliver enveloping effects without requiring conventional bookshelf speakers positioned throughout the room. MartinLogan, Ltd.

Dual Folded Motion XT Tweeters

The ElectroMotion FX2 uses two 1.25 × 2.4-inch Folded Motion XT transducers, each driven by a substantially larger 4.5 × 2.75-inch diaphragm.

MartinLogan states that the Folded Motion XT tweeter has approximately 40% more radiating surface area than the Folded Motion tweeters used in its standard Motion Series designs. The increased surface area expands bandwidth and efficiency while maintaining the low-distortion characteristics of the folded-diaphragm architecture. MartinLogan, Ltd.

160° Wide-Dispersion Surround Array

Rather than focusing high-frequency energy directly at a single listening position, the two Folded Motion XT tweeters are arranged to produce an exceptionally broad 160° horizontal dispersion pattern with 30° vertical dispersion. MartinLogan, Ltd.

This wide-dispersion architecture is specifically designed for surround applications, helping create a larger, more continuous sound field across multiple seating positions.

6.5-Inch Woofer

A 6.5-inch paper-cone woofer with a cast-aluminum basket handles low and midrange frequencies. The driver operates in a ported enclosure using two bass-reflex ports and crosses to the Folded Motion XT array at 2,300 Hz. MartinLogan, Ltd.

The result is a specified frequency response of 55–25,000 Hz ±3 dB, giving the FX2 substantial extension for a compact dedicated surround loudspeaker. MartinLogan, Ltd.

High-Efficiency Home Theater Performance

With 93 dB sensitivity, the ElectroMotion FX2 can generate substantial output without demanding extreme amplifier power. MartinLogan recommends 20–200 watts per channel, with a nominal impedance of 5 ohms and compatibility with amplifiers rated for 4-, 6-, or 8-ohm speakers. MartinLogan, Ltd.

This combination of sensitivity, power handling, and broad dispersion makes the FX2 particularly well suited to larger rooms and high-output multichannel systems.

Flexible Wall & Corner Placement

The ElectroMotion FX2 was designed specifically around real-world theater installation. It can be installed on a flat wall, in a corner, or on an angled wall, giving system designers considerably more flexibility when positioning side and rear surrounds. MartinLogan, Ltd.

When mounted flat against a wall, the cabinet projects only 6.8 inches into the room, helping maintain a clean architectural appearance without moving to an in-wall loudspeaker. MartinLogan, Ltd.

Technical Details

MartinLogan's current product page specifies 93 dB sensitivity. An older manufacturer brochure lists 91 dB, while the current page and owner's manual both state 93 dB, so 93 dB is the appropriate specification for the listing. MartinLogan, Ltd.
