Product Overview

The JBL Control 31 is a two-way high-output indoor/outdoor monitor loudspeaker built for high-fidelity foreground music and speech reinforcement in commercial AV environments. This compact surface-mount installation speaker combines extended bandwidth with well-controlled, symmetrical coverage, making it suitable for atriums, covered patios, themed retail, and multi-purpose spaces. An integrated 70V/100V transformer with an 8-ohm bypass lets it serve distributed audio systems or discrete low-impedance zones. The included WeatherMax grille and JBL InvisiBall mounting system support durable, aimable indoor or outdoor placement.

Product Description

The Control 31 uses high-power components, a computer-optimized horn, and a complex crossover network to achieve smooth, powerful response and defined coverage from a compact enclosure. A 250 mm (10 in) woven-fiberglass cone low-frequency driver with a 52 mm (2 in) high-temperature voice coil provides high sensitivity and output stability, while the high-output 2414H-C compression driver with a 25 mm (1 in) exit and high-temperature polymer diaphragm delivers clear high frequencies at low distortion. The speaker handles 250 W in the 8-ohm thru setting and includes a 150 W transformer for 70V or 100V distributed lines with an 8-ohm bypass. A WeatherMax multi-layer grille (with an optional marine-kit grille for salt-air environments) supports both indoor and outdoor installation, and the InvisiBall mounting hardware plus ten 6 mm attachment points and optional U-bracket allow precise aiming.
