MartinLogan Motion 8i 2-way wall/floor standing front speaker pair black

Inspired by MartinLogan's ultra-high-end electrostatic loudspeakers, the Motion® Series was created to deliver extraordinary sound for your home theater or stereo system. MartinLogan's dedicated in-house engineers thoughtfully crafted the Motion Series to create an extremely affordable and compact product line that seamlessly pairs our extraordinary Folded Motion® transducers with powerful, compact bass technology. The result is smooth, refined sound with extraordinary dynamic range and stunning clarity.

Motion 8i Compact Loudspeaker

Audiophile performance without an audiophile price tag. Inspired by the clarity and detail of MartinLogan's high-end electrostatic loudspeakers, the Motion 8i features a Folded Motion tweeter, dual 4-inch paper cone woofers, and a proprietary Vojtko crossover network in a compact, affordable package. Flexible installation options allow for tabletop or in-wall installation. The Motion 8i mounts horizontally or vertically, making it ideal for placement around a wall-mounted flat-screen television. The Motion 8i also features push-style interlocking posts that accept banana jacks. Available in gloss black.

Engineering, No Compromise

What makes the Motion Series sound so amazing? MartinLogan's dedicated in-house design and engineering team began by utilizing and refining the most advanced, compact technologies and combining them with innovative engineering and time-tested cabinet construction techniques. The result is emotionally engaging sound that rivals (and more often than not, defeats) traditional loudspeakers of similar size and price. Our “no compromise” philosophy gives the Motion Series a unique sound you won't find anywhere else.

Electrostatic-Inspired Sound

The success of the Motion Series is directly attributed to its close relationship to MartinLogan's legendary high-end electrostatic loudspeakers. The desire to bring that level of performance into a more traditional loudspeaker at a more affordable price drove the initial design imperatives that created the Motion Series.

Folded Motion ® Tweeter

MartinLogan's signature Folded Motion tweeter uses an extremely low-mass diaphragm that "squeezes" air, requiring significantly less excursion than the typical 1-inch dome tweeter. Its folded design allows for a much larger surface area (compared to that of a typical 1-inch dome tweeter), controlled dispersion characteristics, and virtually no distortion. It is a marvel of audio engineering that delivers much of the high-frequency detail and speed of a large dynamic electrostatic panel in a small space.

Proprietary Vojtko™ Crossover Networks

Compact Motion Series loudspeakers feature proprietary Vojtko crossover networks that utilize custom air-core voice coil inductors, low DCR steel-laminate inductors, polyester film, and low DF electrolytic capacitors for a seamless sonic presentation.

Vojtko crossovers are named after MartinLogan's chief audio technologist, Joe Vojtko. His unique approach to crossover design is as big a part of the "MartinLogan Sound" as electrostatic and Folded Motion thin-film driver technologies. A Vojtko crossover is less a set of design requirements than a philosophy. Vojtko crossovers are designed so that all drivers are kept in their optimal frequency range and balanced with each other. The drivers themselves are as much a part of a Vojtko crossover as the capacitors and resistors. Before any crossover design begins, the drivers are carefully selected or designed to operate within a very intentional frequency range and with precise, predictable performance parameters. Vojtko crossovers are always made from high-quality parts and care is taken to avoid overly complex topologies, an easy goal with the careful selection of woofers and tweeters. The final (and most critical) aspect of a Vojtko Crossover is that the final voice is conducted in a space that is indicative of a real-world environment. This pragmatic approach allows MartinLogan loudspeakers to sound their best in real-world rooms.

Modern Curves and Luxurious Finishes

After honing in on the acoustic details, MartinLogan designers focused on an elegant yet understated style that complements flat-panel televisions and other high-end components. To achieve this, we gave the Motion compact bookshelf and center channel speakers a flawless gloss black finish and compact, slim enclosures. The subtle curves, along with MartinLogan's signature perforated grille, add a timeless, elegant look.

Easy Hookup

Convenient, premium push-style binding posts are recessed into the speaker cabinet along with curved guides that allow cables to slide into place effortlessly. These binding posts are also designed to facilitate the use of banana plugs.
