The JBL CONTROL 28-1 is a versatile, high-output loudspeaker engineered for robust background and foreground audio in both indoor and outdoor commercial environments. This two-way speaker system features an 8-inch mineral-filled polypropylene woofer and a 1-inch titanium diaphragm compression driver, delivering powerful, clear sound with extended frequency response suitable for music and speech. Its fully sealed, rotationally molded polyethylene enclosure is inherently weather-resistant and UV-stabilized, providing durable protection against rain, humidity, salt fog, and temperature extremes. This makes it an ideal solution for applications such as restaurants with patios, hotel pool areas, shopping centers, transportation hubs, and industrial sites where reliable performance in variable conditions is required.

Acoustically, the CONTROL 28-1 is designed with a wide dispersion pattern to ensure even coverage across broad listening areas. The compression driver is coupled with a constant-directivity horn that maintains consistent high-frequency output both on and off-axis, enhancing vocal intelligibility and musical clarity. The speaker's high sensitivity allows it to produce substantial sound pressure levels with moderate amplifier power, contributing to system efficiency. Its capability to handle significant continuous power enables it to serve as a primary sound source in foreground applications or provide ample output for background music across larger zones, offering flexibility in system design.

Installation is facilitated by an integrated U-bracket yoke that allows for 180 degrees of vertical tilt adjustment, enabling precise aiming for optimal sound projection. Multiple mounting options are supported, including wall, ceiling, pole, or parapet mounting, with all necessary hardware included. The input terminal cup is gasketed and features barrier strip connectors, maintaining the environmental seal. By combining high-output performance, true environmental durability, and flexible mounting, the JBL CONTROL 28-1 provides audio consultants and installers with a reliable, all-weather speaker solution capable of delivering high-quality sound in virtually any commercial setting.
