Martin Logan Motion 8i Stylish and Compact Center Channel Speaker

$369

This was part of a smaller home theater from one of our clients until very recently. It was used with a pair of Martin Logan Motion 4i series bookshelf speakers for about a year. 

A fantastic looking smaller audiophile system that's also wall mountable as shown on their website. This is the current and larger center channel model from Martin Logan that sells for $449. The smaller 6i is $299.

This 8i speaker is in excelent condition. I looked and couldn't find a noticeable mark anywhere. It's probably a 9/10 on our physical condition scale, but we rarely ever grant a 9, and maybe the buyer will use a jewelers loupe to look for something. So we rated it an 8/10 to be safe.

Plus it comes with its official grille to show off the Folded Motion Transducer that's front and center (previous version of this center channel had a non-removable grille).

Stylish and Compact
Inspired by MartinLogan's ultra-high-end electrostatic loudspeakers, the Motion® Series was created to provide stunning sound for your ultimate-performance home theater or stereo. 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. The result is a smooth, refined sound with stunning dynamic range and jaw-dropping clarity.

Motion 8i Compact Speaker
Audiophile performance without an audiophile price. 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. Flexible installation options allow table top or on-wall installation. Motion 8i mounts horizontally or vertically, ideal for placement around a wall-mounted flat screen television. Motion 8i also features recessed push-style binding posts that accommodate banana jacks. Available in gloss black.

Engineering, Without Compromises
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-honored cabinet construction techniques. The result is an emotionally engaging sound that rivals (and most times trounces) traditional loudspeakers of similar size and price. Our 'no compromise' philosophy gives Motion Series a unique sound you won't find anywhere else.

Sound Inspired by Electrostatic Speakers
The success of the Motion Series is directly attributed to its close relation to MartinLogan’s legendary ultra-high-end electrostatic loudspeakers. 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.

Folded Motion® Tweeters
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. 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. 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.

Proprietary Vojtko ™ Crossover Networks
Compact 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.

Vojtko crossovers are named after MartinLogan's chief audio technologist, Joe Vojtko. 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. A Vojtko crossover isn't so much a set of design requirements as it is a philosophy. Vojtko crossovers are designed in such a way that all drivers are kept within their optimal frequency range and balanced with one another. The drivers themselves are as much a part of a Vojtko crossover as are capacitors and resistors. 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. 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. The final (and most critical) aspect of a Vojtko Crossover is that final voicing is conducted in a space that is indicative of a real-world environment. This pragmatic approach allows MartinLogan speakers to sound their best in real-world rooms.

Modern Curves and Luxurious Finish
After refining the perfecting the acoustic details, MartinLogan designers focused on elegant yet understated styling that complements flat-panel televisions and other high-end components. To achieve this, we gave compact Motion bookshelf and center channel speakers a flawless gloss black finish and compact, slender enclosures. Subtle curves, along with MartinLogan's signature perforated grille, add to the elegant and timeless look.
