Wisdom Audio Sage Cinema Line 4

Reference Line-Source Cinema Loudspeaker | The Grid HiFi

Four Modules. 96 Inches of Planar Magnetic Performance.

The Wisdom Audio Sage Cinema Line 4 is an architectural line-source loudspeaker engineered for large private cinemas, multi-tier theaters, and high-performance media rooms.

Standing 102 inches tall, it combines four 24-inch planar magnetic drivers into a 96-inch array, supported by twelve high-output woofers. With 1,000 watts of continuous power handling and 98 dB sensitivity, the Line 4 is designed to deliver the scale and dynamic capability demanded by cinematic soundtracks and live music reproduction.

Its architectural construction allows the system to be concealed behind an acoustically transparent projection screen or integrated into a custom theater wall.

Planar Magnetic Precision

Wisdom Audio's planar magnetic technology uses a lightweight diaphragm driven across its surface rather than relying on a conventional cone-and-voice-coil arrangement.

The design emphasizes fast response and detailed reproduction, allowing the loudspeaker to handle delicate dialogue, atmospheric effects, and complex musical passages.

In the Line 4, the extended driver array provides the scale required for a large listening environment while retaining the characteristics of Wisdom Audio's planar magnetic architecture.

High-Output Bass Integration

A dedicated woofer section complements the planar magnetic drivers, extending the loudspeaker's operating range and providing the output required for dynamic cinema reproduction.

The woofer and planar magnetic sections are designed to operate together through an external active crossover.

This allows the system designer to manage their integration through appropriate amplification, digital signal processing, and calibration.

Designed for Active Operation

The Sage Cinema Line 4 is intended for a professionally engineered active loudspeaker system.

Its separate driver sections require dedicated amplification and crossover processing rather than a conventional single-channel passive speaker connection.

With the appropriate DSP configuration, the installer can establish crossover frequencies, equalization, level matching, and timing as part of the theater's commissioning process.

This makes the Line 4 a component of a complete cinema architecture—not simply a loudspeaker selected in isolation.

Architectural Integration

The Line 4 is designed for installations where loudspeaker placement, screen construction, and room acoustics are considered from the beginning.

Its modular format supports integration into custom theater walls and behind acoustically transparent projection screens.

For a large private cinema, this allows the front soundstage to be positioned around the picture and seating geometry without compromising the room's architectural design.

Technical Specifications

Design Your Wisdom Audio Cinema at The Grid HiFi

A loudspeaker of this scale deserves a room designed around its capabilities.

At The Grid HiFi in Houston, we develop complete private cinemas that bring together architectural loudspeakers, amplification, surround processing, projection, acoustic treatment, and system calibration.

For a Sage Cinema Line 4 installation, our team can evaluate the room dimensions, screen size, seating arrangement, and required output levels before specifying the appropriate loudspeaker configuration and supporting electronics.

From the initial layout to final calibration, we design the system as a complete experience.
