About this product
The Motion Discrete Cinema Series is engineered for high-output clarity and cinematic presence. By focusing the design on the critical midrange and high-frequency bands, we’ve optimized every millimeter for maximum impact. To complete the spectrum, we recommend pairing these speakers with a high performance MartinLogan subwoofer like the Dynamo Foundation, Dynamo, or Abyss series. This allows the Discrete Series to focus on what it does best, delivering a massive, detailed soundstage, while our subwoofers handle the physical demands of low-frequency extension. This approach creates a specialized partnership that respects the laws of physics, letting both speaker and subwoofer play within their optimal ranges.
Features
The MartinLogan Sound
Gen2 Folded Motion Tweeters
Motion Waveguide
Controlled Dispersion
Woven Fiberglass Woofers
The lightweight and strong Woven Fiberglass woofer in the Discrete Cinema series is perfectly suited for keeping pace with the Gen2 FMT, providing crystal clear dialogue and vocals, as well as lifelike instrumentals.
McCracken-Vojtko Crossovers
The culmination of combining extensive anechoic, in-room measurements, and multiple blind listening tests with the low distortion philosophy of MartinLogan’s signature Vojtko Crossover. Through this process each speaker was refined to achieve peak performance.
Soundbar 75 | The 75” Match
Optimized for 75” class displays. This model increases driver count across all channels, doubling the woofers in the center channel and expanding the left/right channels for a broader, more dynamic soundstage.
Attachment Ready
The perfect upgrade path for customers moving away from mass-market active soundbars toward a true high-fidelity component system.
Universal Wall Bracket Included
Every Motion Discrete Cinema speaker comes with a high-quality, low-profile wall mount included for maximum versatility. The bracket system allows for easy leveling and micro-adjustments during installation. It's also engineered to keep the speaker's depth aligned with the TV.
Optional TV Bracket (Sold Separately)
This accessory allows the speaker to be hard-mounted directly to the TV's VESA pattern or dedicated frame points. This ensures the speaker 'travels' with the TB if a pull-out or articulating mount is used.
The Invisible Engine: MartinLogan USR-51
The Motion Discrete Cinema Series and the MartinLogan USR-51 (sold separate) offer a specialized solution to a common design challenge: delivering a high-performance 5.1 cinematic experience without the traditional hardware footprint. This pairing allows you to bypass the compromises of furniture-bound systems, preserving the architectural integrity of the room while delivering world-class audio.
