![]() ![]() Vojtko crossovers are always built from high-quality parts, and care is taken to avoid overly complex topologies-a straightforward objective due to the careful selection of woofers and tweeters. Before the design of any crossover begins, drivers are carefully selected or designed to operate within a very intentional frequency range and with precise and predictable performance parameters. ![]() The drivers themselves are as much a part of a Vojtko crossover as are capacitors and resistors. Vojtko crossovers are designed in such a way that all drivers are kept within their optimal frequency range and balanced with one another. A Vojtko crossover isn’t so much a set of design requirements as it is a philosophy. His unique approach to crossover design is as big of a part of the “MartinLogan Sound” as are electrostatic and Folded Motion thin-film driver technologies. Vojtko crossovers are named after MartinLogan’s chief audio technologist, Joe Vojtko. It’s a miracle of audio engineering that’s able to deliver much of the high-frequency detail and speed of a large, dynamic electrostatic panel in a small space.Ĭompact Motion Series speakers feature proprietary Vojtko crossover networks using custom air core coil inductors, low DCR steel laminate inductors, and polyester film and low-DF electrolytic capacitors for a seamless sonic presentation. Its folded design allows for a much larger surface area (compared to that of a regular 1-inch dome tweeter), controlled dispersion characteristics, and vanishingly low distortion. MartinLogan’s signature Folded Motion tweeter utilizes an extremely low mass diaphragm that “squeezes” air, thus demanding significantly less excursion than the typical 1-inch dome tweeter. The desire to transmute that level of performance into a more traditional loudspeaker at a more affordable price drove the initial design imperatives that created the Motion Series. The success of the Motion Series is directly attributed to its close relation to MartinLogan’s legendary ultra-high-end electrostatic loudspeakers. Our ‘no compromise’ philosophy gives Motion Series a unique sound you won’t find anywhere else. The result is an emotionally engaging sound that rivals (and most times trounces) traditional loudspeakers of similar size and price. What makes the Motion Series sound so amazing? MartinLogan’s dedicated in-house engineering and design team started by utilizing and refining the most advanced, compact technologies and combining them with innovative engineering and time-honoured cabinet construction techniques. Motion 8i also features recessed push-style binding posts that accommodate banana jacks. ![]() Motion 8i mounts horizontally or vertically, ideal for placement around a wall-mounted flat-screen television. Flexible installation options allow table top or on-wall installation. Inspired by the clarity and detail of MartinLogan’s ultra-high-end electrostatic loudspeakers, Motion 8i features a Folded Motion tweeter, dual 4-inch paper cone woofers, and a proprietary Vojtko crossover network in a compact and affordable package. The result is a smooth, refined sound with stunning dynamic range and jaw-dropping clarity.Īudiophile performance without an audiophile price. MartinLogan’s dedicated in-house engineers carefully crafted the Motion Series to create an extremely affordable and compact product line that seamlessly blends our exquisite Folded Motion® transducers with powerful, compact bass technology. Inspired by MartinLogan’s ultra-high-end electrostatic loudspeakers, the Motion® Series was created to provide stunning sound for your ultimate-performance home theatre or stereo. ![]()
