Product Description

MartinLogan Motion 8i Center Channel Speaker

Jaw-Dropping Clarity

MartinLogan’s Motion 8i is a sleek, high performance center channel speaker that looks great with today’s TVs. Inspired by the clarity and detail of MartinLogan’s ultra-high-end electrostatic loudspeakers, Motion 8i features a Folded Motion tweeter and powerful bass technology in a compact and affordable package. Set it under you set or mount it on the wall for superb sound quality.

The Motion 8i is particularly well equipped to excel with music, movies, and other multi-channel entertainment sources. Its driver complement consists of a 1″ x 1.4″ Folded Motion high-frequency transducer with a 5.25″ x 1.75″ diaphragm plus two 4″ low frequency drivers with stamped steel basket in a non-resonant asymmetrical chamber format wit rigid structured dust cap to reduce cone break-up modes.

The Motion i Series

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 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 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.

Folded Motion Tweeter

MartinLogan’s exclusive and highly innovative Folded Motion Tweeter helps gives Motion i speakers their fantastically realistic highs. Lightning fast transient response, combined with a large surface area creates clear, highly dynamic, and precise sound.

The Folded Motion Tweeter works by moving air (which creates sound) perpendicular to the folded ridges of the diaphragm, similar to how an accordion works. This extremely low mass diaphragm “squeezes” air and requires almost 90 percent less excursion than the typical 1″ dome tweeter, which drastically minimizes distortion while providing a lighting fast response time. The increased surface area also provides a wide, yet controlled sound dispersion to create a realistic and carefully etched sound stage.

Vojtko Crossover

Contributing to the superb performance is the legendary Vojtko crossover. It is carefully hand-built using only the finest polyester film and low DF electrolytic capacitors, custom air-core coils, and low DCR steel laminate inductor for vanishingly low distortion and seamless driver integration. This precision-tuned network preserves even the most microscopic sonic nuances while handling the full dynamics of any source.

Curve Appeal

Complementing Motion’s sonic accuracy is elegant yet understated styling. Flawless high-gloss, piano black finishes and subtle curves, along with MartinLogan’s signature perforated grille, gives Motion i Series speakers an elegant and timeless look. Tower models feature a real-wood veneer finish and a stylish aesthetic certain to blend with any decor.

Built With Outstanding Features, The Motion 8i Center Channel Speaker Looks As Good As It Sounds
