Martin Logan Motion 2i Speaker - Pair
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.
Engineering Genius
What makes the Motion Series sound so amazing? MartinLogan's dedicated in-house engineering team started by utilizing and refining the most advanced, compact technologies and combining them with innovative engineering. The result is an emotionally engaging sound that rivals (and most times trounces) traditional loudspeakers of similar size and price.

Folded Motion® Tweeters
The signature Folded Motion tweeters utilize extremely low mass diaphragms that "squeeze" air, and require significantly less excursion than the typical 1-inch dome tweeter, which drastically minimizes distortion while providing a lightning fast response time. The increased surface area also provides a wide, yet controlled sound dispersion to create a realistic and carefully etched sound stage.
Engineered Curves
Flexible installation options allow table top or on-wall installation of all four speakers. The Motion 2i and 4i bookshelf speakers can also mount upside down to facilitate placement high on a wall. The Motion 6i and 8i mount horizontally or vertically around a wall-mounted flat screen television.
