MartinLogan Motion Discrete Cinema 3-Channel Passive Soundbar for 85-Inch Class TVs - DISCRETECINEMABAR85

MartinLogan DISCRETECINEMABAR85 Motion Discrete Cinema 3-Channel Passive Soundbar for 85-Inch Class TVs

The MartinLogan DISCRETECINEMABAR85 Motion Discrete Cinema Series three-channel passive soundbar combines discrete left, center and right channels in a single 15-driver enclosure scaled for an 85 in class television. Twelve 4 in woven-fiberglass cones and three Gen2 Folded Motion Tweeters with Folded Motion Waveguides create a detailed front soundstage with controlled 90 degrees x 90 degrees dispersion, while the sealed extruded aluminum cabinet remains slim and rigid. The included low-profile wall bracket, concealed cable channels and removable tool-free wire connector support a clean, flush setup. External amplification is required¹, and MartinLogan recommends adding a compatible high-performance subwoofer for full low-frequency extension².

Key Features

15-Driver Three-Channel Soundstage

The MartinLogan DISCRETECINEMABAR85 array assigns dedicated drivers to left, center and right channels, so the front stage comes from three separately amplified paths in one enclosure. This layout gives an 85 in class display a physically proportioned audio partner without placing three individual speakers across the front of the room.

Passive Architecture and Amplifier Flexibility

As a passive soundbar design, the DISCRETECINEMABAR85 gives the installer control over the external amplification. Recommended amplifier power is 20-280 Watts, while its 4 Ohm impedance is compatible with amplifiers rated for 4, 6 or 8 Ohms.

Woven Fiberglass Technology

The twelve 4 in cones use a stiff, lightweight woven-fiberglass material related to current full-size Motion Series speakers. This material supports strong output from the shallow cabinet and consistent voicing when the MartinLogan soundbar joins other Motion speakers.

Gen2 Folded Motion Tweeters and 90 Degrees x 90 Degrees Dispersion

Three Gen2 Folded Motion Tweeters work with Folded Motion Waveguides to deliver precise high-frequency detail across a controlled 90 degrees x 90 degrees pattern. By managing dispersion, the design is intended to reduce unwanted room reflections that can blur clarity.

Rigid Extruded Aluminum Enclosure

Thin aluminum walls allow more of the sealed cabinet's interior to be used by the drivers while resisting flex and vibration. Curved endcaps soften the transition between the speaker and the straight lines of the display, helping the black enclosure recede into a minimalist installation.

Flush Mounting and Hidden Wiring

An ultra-slim low-profile wall bracket is included for a centered, close-to-wall presentation, with adjustment available during alignment. Rear cable-management channels keep speaker wire out of sight, and hidden hardware preserves the clean visual line beneath the television.

Tool-Free Connections and Display-Centric Mounting

The removable connector lets the installer terminate speaker wire before lifting the soundbar into place; tension levers secure the conductors without a screwdriver. For articulating installations, a separately sold display-centric bracket can attach through the television mounting pattern so the bar moves with the screen and the gap can be controlled³.

Recommended Subwoofer Pairing

With a published response of 100-25,000 Hz +/- 3 dB, the Soundbar 85 focuses on the front stage's midrange and high-frequency detail. Pairing it with a compatible high-performance subwoofer adds low-frequency extension while allowing each speaker to work in its intended range.
