Key Features
Product Description
The JBL Control 31 is a high-output 2-way indoor/outdoor monitor loudspeaker designed for applications requiring powerful, high-fidelity sound with wide and consistent coverage. It combines a 10-inch woven-fiberglass LF driver with JBL’s high-output 2414H-C compression driver to deliver extended bandwidth and smooth, controlled performance.
Its 110° × 110° symmetrical coverage provides consistent sound distribution whether the speaker is installed vertically or horizontally. The Control 31 also features a weather-resistant IP55-rated enclosure, WeatherMax™ grille and corrosion-resistant construction, making it suitable for demanding indoor and outdoor installations.
The speaker offers 8Ω direct operation with 250 W capability, as well as a built-in 150 W transformer for 70V/100V distributed audio systems. JBL's included InvisiBall® mounting system provides flexible and discreet installation, while multiple attachment points allow suspension or optional U-bracket mounting.
