Product Details

MartinLogan Motion 4i Gloss Black Bookshelf Speaker - MO4IBL

Audiophile performance without an audiophile price. 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. 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 jawdropping 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 of all four speakers. Motion 2i and 4i bookshelf speakers can also mount upside down to facilitate placement high on a wall. Motion 6i and 8i can mount horizontally or vertically around a wall-mounted flat screen television.

  • Cascading Bass Reflex Port
    MartinLogan engineers were faced with a daunting task—create a compact speaker with low-end bass reproduction found in speakers much, much larger. After many sleepless night and a myriad of prototypes, they created the Cascading Bass Reflex Port. This brilliant solution allows a long tuned port, which is folded over itself (think of a trombone's tuning arm) to be compacted and squeezed into the Motion 4i. The result is amazingly detailed low bass that can play at high volumes with minimum distortion—all thanks to the elegantly simple cascading fold that slows down and controls the air motion of the bass waves
