Product Overview
The JBL Control 50 Series subwoofer-satellite loudspeaker system provides high fidelity sound in restaurants, retail stores, music cafes, health clubs, theme bars, leisure venues, or any location where full-range high fidelity foreground/background music is required from a surface-mount system.
Control 52 Satellite Speaker
The Control 52 satellite loudspeaker produces superb high fidelity sound via a low-distortion 60 mm (2½ inch) driver. It features a secondary bucking magnet for high efficiency, a rubber half roll surround for enhanced bass performance, a 19 mm (0.75 inch) copper clad aluminum wire voice coil on a vented Nomex® former for high fidelity and reliability, and a copper-capped pole piece for more consistent impedance and extended high frequency response. The included wall bracket allows each speaker to be angled up to 45° off-axis.
Control 50 Subwoofer
The 150 Watt (600 Watt peak) Control 50S/T subwoofer contains a high-power, long-excursion, 200 mm (8 inch) driver. This driver features an extremely robust high-mass cone for extended low frequency response, a 38 mm (1.5 inch) 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 includes a two-piece easy-mount wall-bracket that installs quickly. The multi-point wall portion attaches to the wall, and the self-guiding speaker-mounted bracket drops into place for secure attachment. A cover over the Control 50S/T terminal cup keeps wiring neat. The Control 50S/T operates in mono. The integrated crossover network provides proper signal routing and four satellite output connectors allow connection for up to four Control 52 satellite loudspeakers. A 'Loop Out' connector is also provided for routing the full-range input signal to other loudspeakers or systems.
System Configuration
The Control 50 Series is a versatile system, available as packaged systems or separate components. The C50PACK system includes four Control 52 satellite speakers and one Control 50S/T subwoofer. For smaller spaces, the Control 50S/T subwoofer can be used with two Control 52 satellite speakers. The system operates in mono. The Control 50S/T and Control 52 can be mixed with the Control 40 Series in-ceiling models (Control 40CS/T subwoofer and Control 42 satellite speaker) to meet diverse application requirements.

²Continuous Pink noise rating is IEC-shaped pink noise with a 6 dB crest factor for 100 hours continuously. Continuous Program Power is a conservative expression of the system's ability to handle normal speech and music program material, and is defined as 3 dB above the Continuous Pink Noise rating.

Application Notes
Subwoofer Placement for Tonal Balance
Subwoofer location relative to walls, floor, or ceiling significantly impacts system tonal balance. For two satellite speakers, placing the subwoofer centrally on a wall is recommended. For four satellite speakers (like the C50PACK system), central wall placement provides good bass levels. Locating the subwoofer at a two-boundary junction (wall-floor or wall-wall) or in a corner enhances bass. External equalization (tone controls, DSP) can further adjust tonal balance.
Port Clearance
Ensure a minimum of 50 cm (2 feet) clearance between the Control 50S/T subwoofer's port and any adjacent wall surface to avoid blocking the port.
Using Control 52 without Control 50S/T Subwoofer
The Control 52 speaker can be damaged if driven with frequencies below 140 Hz. The Control 50S/T subwoofer provides the necessary high-pass filter. If using the Control 52 independently, the signal must be high-passed using a passive high-pass filter, electronic high-pass, electronic crossover, or DSP (recommended: 140 Hz, 24 dB/oct). Failure to high-pass can result in speaker damage.
Wall Bracket Orientation
Install the wall bracket so the subwoofer drops down into it, ensuring it clicks into place. Do not install the bracket sideways or on a ceiling. Refer to the Control 50S/T Installation Guide for details. To remove the subwoofer, push the release clip towards the wall with a long screwdriver from the top side of the bracket.
Secondary Safety Cable
When installing the subwoofer, always use a secondary safety cable attached to the separate 6 mm insert located on the back/wall side of the subwoofer.
