JBL Control 31 Two-Way High-Output Indoor-Outdoor Monitor Speaker

Quick Overview


250 mm (10 in) woven fiberglass cone LF driver with 52 mm (2 in) voicecoil.
High-output 2414H-C compression driver with 25 mm (1 in) exit,
unique (patented) design and high-temperature polymer diaphragm.
Highly outdoor-capable design with included WeatherMax™
multi-layer grille and optional marine-kit grille for salt-air environments.

The Control 31 utilizes high-power components, computer optimized horn, and a complex network to achieve smooth, powerful high-fidelity performance, extended bandwidth, and well-controlled defined coverage from a compact loudspeaker. The 250 mm (10 inch) low-frequency driver features a woven fiberglass cone and pure butyl rubber surround for weather resistance (and clean sound quality), and the basket is rear-loaded into the baffle to minimize exposure. It also has a high-temperature fiberglass voice coil former for high sensitivity, high output capability and stable performance for wide-bandwidth sound reinforcement in small venues and salt environments (with optional marine-kit grille). The optimized cone geometry provides a smooth frequency response and good off-axis performance. A linear suspension spider provides low distortion, while FEA-optimized motor construction produces minimum harmonic distortion. An aluminum coupler ring outside the pole post further reduces distortion and further increases the sensitivity. The high-output, high frequency compression driver features a unique, high-temperature polymer diaphragm, and fluid-cooling for high output levels with low distortion. The grille is thermoset composite coated and stands up well to UV as well as humidity. The grille is backed with JBL’s WeatherMax™ multi-layer foam and tight-weave screening to help prevent incursion of water. Nickel/zinc rust-resistant terminals ensure a secure input connection. An MTC-PC2 sealed-entrance cover is included to further protect the speaker’s terminals. The white-version cabinets are painted with a UV-resistant finish to resist yellowing due to UV exposure Using JBL’s advanced ImageControl™ process for accurate, low-distortion control, the high-frequency waveguide gives a smooth frequency response and excellent sound character throughout the frequency – over the entire listening area. Its 110° x 110° symmetrical coverage provides the same coverage whether the cabinet is installed in vertical or horizontal orientation. Designed for minimal insertion loss and reduced saturation, the line distribution transformer allows for use on either 70V or 100V distributed speaker lines. In the Thru setting, the 8 ohm impedance allows for the use of up to two speakers on a 4-ohm capable amplifier channel. The included InvisiBall mounting method is simple to install, aims easily and provides theft deterrence. InvisiBall allows horizontal rotation of up to 41° off-axis and vertical rotation of up to 36° (horn end inward) or 23° (woofer end inward). Attachment points for the optional MTC-30UB (& “-WH” for white) U-bracket allow for compact installation and are particularly useful for low-profile applications. JBL’s Control 31s have a better low-frequency response and wider coverage than the 12" woofers of Atlas and EV, but those have higher sensitivity due to their larger cone area and cost more.
