JBL CONTROL 50S/T Surface-Mount Subwoofer for Subwoofer-Satellite Loudspeaker System

The 150 Watt (600 Watt peak) Control 50S/T subwoofer contains a high-power, long-excursion, 200 mm (8 inch) driver which features an extremely robust high-mass cone for extended low frequency response, a 38 mm (1.5 in) 4-layer copper voice coil for high motor strength, an aluminum former for good transient response, and a rubber half roll surround for enhanced bass performance. The Control 50S/T’s included two-piece easy-mount wall-bracket installs quickly: The multi-point wall portion of the bracket attached to the wall and the self-guiding speaker-mounted bracket drops into place for a secure attachment. A cover over the Control 50S/T terminal cup keeps wiring neat. The Control 50S/T is mono. The crossover network built into the subwoofer provides proper signal routing and four satellite output connectors allow connection of the wires for the four Control 52 satellite loudspeakers. A Loop Out connector is also provided on the subwoofer for looping the full-range input signal to other loudspeakers or to other subwoofer/satellite systems.

About the JBL CONTROL 50S/T Surface-Mount Subwoofer for Subwoofer-Satellite Loudspeaker System

The JBL CONTROL 50S/T is a specialized surface-mount subwoofer engineered to serve as the low-frequency foundation for subwoofer-satellite loudspeaker systems in professional architectural audio applications. Designed to complement the acclaimed CONTROL series of compact satellite speakers, this model provides the necessary bass extension to create a full-range, high-fidelity listening experience in settings where discrete installation is paramount. Its primary function is to deliver articulate and impactful low-frequency reproduction, enhancing music, multimedia content, and voice reinforcement in environments such as conference rooms, retail stores, restaurants, and hospitality venues. The subwoofer’s design philosophy centers on seamless integration, both acoustically and visually, ensuring it augments the satellite performance without drawing undue attention.

Acoustically, the CONTROL 50S/T features an 8-inch, long-throw woofer housed in a carefully tuned bass-reflex enclosure. This vented design maximizes low-frequency output and efficiency from a compact cabinet, providing deep, musical bass that typical satellite speakers cannot reproduce. A critical component of the system is the included passive crossover network. This network is specifically engineered to filter the incoming full-range signal, sending a high-passed signal to the satellite speakers and directing the appropriate low-frequency content to the subwoofer. This division of labor protects the satellites from distortion, improves their midrange clarity, and allows the subwoofer to handle the demanding bass duties, resulting in a cleaner, more powerful overall system.

The enclosure is constructed from durable, moisture-resistant polypropylene, making it suitable for a variety of indoor environments. Its low-profile, trapezoidal shape is designed for unobtrusive placement in corners, under tables, or mounted on walls, with a white finish that allows it to blend with most interior décors. Installation is straightforward, featuring keyhole slots and provisions for secure surface mounting. By combining a performance-tuned driver, an effective enclosure design, and a dedicated system crossover, the JBL CONTROL 50S/T provides a complete and elegant solution for upgrading any CONTROL series satellite installation into a robust, full-range audio system with enhanced depth and presence.
