Inspired by MartinLogan's ultra-high-end electrostatic loudspeakers, the Motion Series was created to provide stunning sound for your ultimate-performance home theater or stereo. MartinLogan's dedicated in-house engineers carefully crafted the Motion Series to create an extremely affordable and compact product line that seamlessly blends our exquisite Folded Motion transducers with powerful, compact bass technology. The result is a smooth, refined sound with stunning dynamic range and jaw-dropping clarity. Complementing Motion's sonic accuracy is elegant yet understated styling. Flawless finishes and subtle curves, along with our signature perforated grille, give Motion Series speakers an elegant and timeless look. The Motion FX features a wide-dispersion dual Folded Motion tweeter design ideal for rear surround channel applications where the non-direct sound creates a more enveloping sonic experience. Convenient push-style speaker terminals and curved inserts 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.
