JBL Control 19CST In-Ceiling Subwoofer with 70V/100V Transformer (CONTROL 19CST)

The JBL Control 19CST is a professional in-ceiling subwoofer designed to provide powerful low-frequency reinforcement for commercial and installed audio systems. Part of JBL’s Control Contractor Series, the Control 19CST combines deep bass performance, flexible system integration, and discreet ceiling installation for applications requiring enhanced musical impact without the need for visible subwoofer enclosures.

Featuring an 8-inch long-excursion driver, the Control 19CST delivers extended low-frequency response with high output capability and controlled bass reproduction. The long-excursion design allows greater driver movement, enabling the subwoofer to produce powerful, accurate bass while maintaining reliability during continuous professional operation.

The subwoofer provides 100 watts of power handling and includes a built-in 75-watt 70V/100V transformer, allowing direct integration into constant-voltage distributed audio systems. This transformer configuration provides flexible power selection for commercial installations, making the Control 19CST suitable for a wide range of background music, foreground music, and architectural audio applications.

Designed for professional in-ceiling installation, the Control 19CST includes a complete mounting package with a backcan, grille, and tile rails. These included accessories simplify installation, provide structural support, and help optimize acoustic performance by creating a controlled enclosure environment behind the speaker.

The included backcan helps improve low-frequency consistency by managing rear sound radiation, while the tile rails provide additional support for suspended ceiling installations. This complete installation solution allows contractors to achieve a clean, secure, and professional finish in commercial spaces.

With its discreet ceiling-mounted design and powerful bass output, the Control 19CST is ideal for applications where high-quality low-frequency enhancement is required without compromising architectural aesthetics. It works exceptionally well when paired with JBL Control Series ceiling speakers to create a full-range distributed audio system.

Sold individually and commonly supplied in pairs, the Control 19CST provides flexibility for installations of various sizes, from small commercial spaces to large-scale professional audio projects.

Ideal for restaurants, hotels, retail stores, offices, conference centers, entertainment venues, hospitality spaces, houses of worship, educational facilities, and commercial AV installations, the JBL Control 19CST delivers powerful, discreet, and reliable in-ceiling bass reinforcement for professional sound systems.
