Product Description
The MartinLogan Motion 4i is a sophisticated bookshelf speaker that combines a compact form factor with audiophile-grade performance. It features the signature Folded Motion tweeter, which is engineered to provide a fast response and precise high-frequency detail. This makes the 4i an excellent choice for listeners who want clear and transparent audio in smaller rooms or as part of a high-end surround sound system.
Despite its small footprint, the Motion 4i delivers a rich sound thanks to its 4-inch high-excursion poly cone woofer and a specialized ported enclosure. This design enhances low-frequency extension, providing a balanced audio profile that belies the speaker's size. The elegant curved cabinet with a premium gloss black finish ensures that the speaker looks as good as it sounds, fitting perfectly into modern home decors.
Installation is highly flexible, as the Motion 4i can be placed on a shelf, stand, or mounted directly to the wall using the included adjustable bracket. Whether used for a dedicated stereo setup or as height/surround channels in a 4K home theater, this speaker offers the perfect blend of MartinLogan’s sonic precision and versatile, space-saving design.
