The JBL CONTROL 19CS is a specialized in-ceiling subwoofer engineered to add dedicated low-frequency extension to distributed audio systems without occupying floor space. As part of the Control Contractor series, it is designed for seamless integration into commercial and residential environments where aesthetic discretion and high-performance bass reproduction are both required. This subwoofer features an 8-inch, long-throw woofer with a robust motor structure, housed in a fully enclosed, shallow-depth back can, allowing it to be installed within standard ceiling constructions. Its primary function is to provide rich, impactful bass for background music, home theater, and multi-zone audio systems in settings such as offices, restaurants, luxury residences, and retail spaces, complementing smaller satellite or in-ceiling full-range speakers.

Acoustically, the subwoofer is designed to operate within a dedicated low-frequency range, typically from below 40 Hz up to 150 Hz, ensuring it handles only the bass content and relieves the main speakers of this demanding task, thereby improving overall system clarity and headroom. The sealed enclosure design provides tight, accurate bass response with good transient speed, avoiding the phase issues sometimes associated with ported designs. The woofer is engineered for high excursion and power handling, allowing it to move significant amounts of air to produce authentic low-frequency effects and musical bass notes, even when concealed above a ceiling plane.

Installation is streamlined for contractor-friendly deployment, featuring a standard round cutout and a low-profile, paintable grille that blends inconspicuously into the ceiling. The unit includes an integrated high-pass crossover output, enabling easy daisy-chaining to full-range satellite speakers, which is a key feature for creating a cohesive 2.1 or multi-subwoofer system layout. Connectivity is achieved via standard speaker wire terminals within the accessible back can. By offering a true subwoofer solution in a ceiling-mount format, the JBL CONTROL 19CS provides audio professionals with a powerful tool to enhance system performance and listener experience while maintaining a clean, uncluttered visual environment.
