Martin Logan Motion 4i Bookshelf / Surround Speaker (Each)

Bigger Sound. Exceptional Detail. Beautifully Compact.

The MartinLogan Motion 4i takes compact loudspeaker performance to an impressive level, combining the company's signature Folded Motion tweeter with a 4-inch mid/bass driver and a carefully tuned bass-reflex enclosure.

Whether used in a dedicated stereo system or as part of a premium home theater, the Motion 4i offers lively dynamics, natural vocals, and a spacious, detailed soundstage.

MartinLogan Folded Motion Technology

The advanced Folded Motion tweeter provides excellent high-frequency articulation, revealing subtle musical textures and cinematic details without sacrificing smoothness.

Impressive Bass and Midrange

A 4-inch paper-cone driver and folded bass-reflex port help the Motion 4i deliver fuller sound than its compact dimensions might suggest. Voices remain intelligible, instruments retain their natural character, and music has convincing energy.

Flexible Installation

The attractive gloss-black cabinet looks at home on a bookshelf or speaker stand. The included wall-mount bracket also makes the Motion 4i an excellent choice for surround-sound installations.
