Motion i Compact Speakers

Inspired by the clarity and detail of MartinLogan’s ultra-high-end electrostatic loudspeakers, Motion 6i feature exquisite Folded Motion tweeters and powerful bass technology in compact and affordable packages.

Folded Motion Tweeter

Key to performance is the lightning fast response of the tweeter’s light-weight diaphragm combined with a large surface area (much larger than a typical one-inch dome tweeter) which together achieve a smooth, refined sound with stunning dynamic range and jaw-dropping clarity—certain to inspire envy in audiophiles and non-audiophiles alike. Precision Vojtko™ crossover topology features custom air core coil inductors, low DCR steel laminate inductors, and polyester film and low DF electrolytic capacitors for a seamless sonic presentation.

Flexible installation options allow table top or on-wall installation. The Motion 6i mount horizontally or vertically around a wall-mounted flat screen television.
