Martin Logan Motion 4i Compact Bookshelf Speaker (Each)


Motion® i Compact Speakers

Inspired by the clarity and detail of MartinLogan’s ultra-high-end electrostatic loudspeakers, Motion 2i, 4i, 6i, and 8i 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.

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.
