The JBL Professional 9320 is a large-format, high-power loudspeaker engineered explicitly for cinematic surround sound applications in commercial movie theaters, premium large format (PLF) auditoriums, and high-end post-production mixing stages. As a dedicated surround channel speaker within JBL's acclaimed Screen Array and 9000 Series cinema systems, its primary design objective is to deliver precise, high-output, and spatially diffuse sound effects and ambient cues that envelop the audience. The speaker features a robust 12-inch differential drive woofer paired with a high-frequency compression driver mounted on a wide-dispersion horn. This combination is optimized to produce the high sound pressure levels and dynamic range required by modern digital cinema soundtracks, while maintaining exceptional clarity and accurate transient response for detailed effects reproduction.

A defining characteristic of the 9320 is its specialized dispersion pattern. The horn and driver geometry are designed to produce a very wide horizontal coverage and a controlled vertical coverage, typically aiming to create a broad, even sound field across multiple rows of seating from a single mounting point. This wide dispersion is critical for surround applications, where the goal is to create an immersive, non-localized ambient field rather than a focused, direct beam of sound. The speaker is built into a trapezoidal-shaped, heavy-duty enclosure constructed from multi-layered plywood with a durable, textured black finish, allowing for flexible mounting in a variety of standard cinema configurations, including directly to walls or as part of a larger array.

The loudspeaker is designed for passive operation, driven by high-power external amplifiers as part of a complete cinema sound system. It is engineered for long-term reliability in commercial 24/7 operation, with components rated for continuous high-output use. Its performance is carefully voiced to integrate seamlessly with JBL's screen channel and subwoofer systems, ensuring a tonally balanced and cohesive soundscape throughout the entire theater. The JBL 9320 exemplifies professional cinema sound design philosophy, providing the power, dispersion, and sonic fidelity necessary to fully realize the immersive audio experience intended by filmmakers, from subtle environmental details to explosive, room-filling effects.
