Features

Overview: The JBL Control 31 is a 70/100 volt speaker designed for commercial applications, both indoor and outdoor. Its improved voicing allows for an extremely flat response, high-fidelity, and extended bandwidth from a 10" woven fiberglass woofer and 1" high-output compression driver, providing up to 110˚ of horizontal and vertical coverage. It can be run in either 70 or 100 volt applications and includes an 8Ω Thru setting as well. Other features include a highly weather-resistant enclosure and flexible mounting options.

Enclosure: Designed for indoor and outdoor use, the Control 31 series speakers have been maximized for weather resistance. They feature a high-impact polystyrene (HIPS) enclosure along with a thermoset composite coated grille with WeatherMax foam lining to minimize water incursion. The woofer is made of woven fiberglass with a butyl rubber surround and the 1" compression driver is made from high temperature polymer. Input terminals are zinc coated  for rust-resistance and can have further protection from the included input terminal cover. The Control 31 carries an IP-55 rating per IEC 529 and exceeds MilSpec 810 for humidity, salt spray, temperature, and UV. It also passes Mil-Std-202F for salt spray.

Mounting: JBL offers flexible mounting options for the Control 31 speaker. Along with mounting on either a vertical or horizontal surface, the speaker can be suspended using any of the ten 6mm suspension points, which can also accommodate JBL's optional U-bracket (sold separately). The speaker can also be wall mounted using the included InvisiBall mounting hardware. The Control 31 speaker has a removable rear socket cover allowing the 2.3" (58mm) ball of the mount to sit inside the speaker. The socket is then tightened, using the included 12" Allen key, via the access hole underneath the removable front grille emblem. The InvisiBall mount allows up to 41˚ of horizontal rotation and up to 36˚ of vertical rotation. A 6mm threaded socket on the rear is provided for a secondary safety attachment point.

70/100 Volt: The Control 31 is designed primarily to be used in 70 and 100 volt applications, but also includes an 8 ohm bypass mode (Thru). Its top-quality, 150 watt, line distribution transformer is designed for minimal insertion loss and reduced saturation. A tap setting adjustment-screw on the rear of the speaker allows for the following 70 and 100 volt wattage options:

• 70 V: 19W, 38W, 75W, 150W
• 100 V: 38W, 75W, 150W
