MartinLogan Motion Discrete Cinema 3-Channel Passive Soundbar for 65-Inch Class TVs - DISCRETECINEMABAR65

MartinLogan DISCRETECINEMABAR65 Motion Discrete Cinema 3-Channel Passive Soundbar for 65-Inch Class TVs

The MartinLogan DISCRETECINEMABAR65 Motion Discrete Cinema Series passive three-channel soundbar combines discrete left, center and right channels in one slim enclosure sized to complement 65 in class displays. Its 9-driver design uses six 4 in woven-fiberglass midrange/bass drivers and three Gen2 Folded Motion Tweeters with Folded Motion Waveguides, delivering a 100-25,000 Hz +/- 3 dB response with controlled 90 degrees x 90 degrees high-frequency dispersion. A rigid sealed aluminum cabinet, included low-profile wall mount, built-in cable management and tool-free connector support a clean installation; external amplification is required.¹

Built for receiver-driven home theaters, this low-profile soundbar solution replaces three separate front speaker cabinets while preserving distinct L/C/R channels, giving large-screen systems a visually discreet design and an expansive front presentation.

Key Features

A Three-Channel Match for 65 in Displays

The MartinLogan DISCRETECINEMABAR65 places discrete left, center and right channels in a single cabinet, creating a complete front soundstage without separate visible front speakers. Its length is calculated to complement the bezel of a 65 in class television, helping the audio system feel visually proportioned to the picture.

Unlike an all-in-one powered model, this design relies on an external amplifier, an important distinction when comparing active and passive soundbars.¹

9-Driver Front Soundstage

Each channel receives one Gen2 Folded Motion Tweeter and two woven-fiberglass drivers, giving all three front channels the same driver arrangement. This scaled driver density helps dialogue, effects and music spread across the screen with the output and detail expected from a larger image.

Gen2 Folded Motion Tweeters and Waveguides

Three Gen2 Folded Motion Tweeters reproduce high-frequency detail, while Folded Motion Waveguides shape their output into controlled 90 degrees x 90 degrees dispersion. Directing more sound toward the listening area helps limit performance-robbing room reflections and supports precise, smooth presentation.

Woven Fiberglass Technology

Six 4 in woven-fiberglass midrange/bass drivers use the same cone-material family as current full-size Motion Series speakers for timbre matching. Their high stiffness-to-mass ratio helps the shallow cabinet produce convincing punch while maintaining clarity through the front channels.

Sealed Extruded Aluminum Cabinet

Thin, rigid aluminum walls provide greater internal air volume than thicker cabinet construction while resisting flex that can color the sound. Curved endcaps soften the transition from speaker to wall, balancing acoustic control with a sculpted look that complements a flat-panel display.

Clean, Adjustable Wall Installation

The included ultra-slim bracket provides alignment adjustment for a centered, flush-looking installation. Rear wire channels conceal speaker cable, and the removable tension-lever connector lets the installer terminate the wire before hanging the soundbar without using a screwdriver on the connector.

Complete the Low-Frequency Foundation

The Motion Discrete Cinema Series concentrates on detailed midrange and high frequencies in a slender enclosure. MartinLogan recommends adding at least one suitable powered subwoofer for full low-frequency extension, allowing the front soundbar to remain visually discreet while the system gains deeper bass.²
