JBL Control 31-WH - 250W 10-inch Passive 2-Way 70V/100V Surface-Mount Loudspeaker with 110 x 110-Degree Coverage in White Finish

The JBL Professional Control 31-WH is a 250W passive 2-way surface-mount loudspeaker, offering high-fidelity audio performance with extended bandwidth and superior coverage. Designed for both indoor and outdoor applications, this loudspeaker delivers clear, powerful sound with smooth frequency response and minimal distortion. The Control 31-WH is ideal for a wide range of venues, including retail stores, outdoor events, sports facilities, theme parks, and hospitality spaces, where high output and durability are essential.

At the core of the Control 31-WH is a 10-inch low-frequency driver with a woven fiberglass cone and pure butyl rubber surround, ensuring both excellent sound quality and weather resistance. The driver is designed to perform optimally even under high-power conditions, with a high-temperature fiberglass voice coil former that ensures stable performance. The cone's optimized geometry enhances the smooth frequency response and improves off-axis performance, while the linear suspension spider helps reduce distortion. FEA-optimized motor construction minimizes harmonic distortion, and an aluminum coupler ring outside the pole post further increases the speaker's sensitivity.

The high-frequency section features JBL's patented 2414H-C compression driver with a 1-inch diaphragm and fluid-cooling for increased power handling. The high-frequency waveguide, designed using JBL's advanced ImageControl process, provides 110° x 110° symmetrical coverage, ensuring even sound distribution throughout the listening area. The speaker maintains consistent performance whether installed horizontally or vertically, offering flexible installation options. The broad frequency range of 33 Hz to 19 kHz and frequency response of 42 Hz to 14 kHz ensures detailed and natural sound reproduction across a wide spectrum of audio content.

The Control 31-WH is equipped with a high-quality transformer for use with 70V or 100V distributed speaker lines. The transformer is designed to minimize insertion loss and reduce saturation, ensuring efficient power distribution. In the Thru setting, the 8-ohm impedance allows for multiple speakers to be used on a loudspeaker line. The speaker's high sensitivity (92 dB, 1W/1m) and power handling capabilities allow it to achieve a maximum SPL of 123 dB peak and 116 dB continuous at 1 meter, making it suitable for large venues and demanding applications.

Weather resistance has been maximized to ensure the speaker performs reliably in various environmental conditions. The low-frequency driver's rear-loaded basket minimizes exposure to the elements, while the high-frequency compression driver features a highly weather-capable polymer diaphragm. The grille is thermoset composite-coated steel, offering UV protection and resistance to humidity, and is backed by WeatherMax multi-layer foam to prevent water intrusion. This makes the Control 31-WH perfect for outdoor environments, with an IEC 529 IP-X5 rating and the ability to withstand extreme weather conditions, including salt spray, UV exposure, and temperature fluctuations.

The Control 31-WH includes the InvisiBall mounting system, which provides easy installation with up to 41° of horizontal rotation and 36° of vertical rotation (horn end inward) or 23° (woofer end inward). This system allows for precise aiming of the speaker to ensure optimal sound coverage. The speaker also features ten 6 mm attachment points for suspension, as well as an optional U-bracket for low-profile installations. The secondary safety attachment point on the back panel offers additional security during installation.

The speaker's robust design is further complemented by its included accessories, which include an MTC-PC2 sealed-entrance cover for the speaker's terminals and the InvisiBall wall-mounting system, along with a 6 mm x 305 mm hex wrench. Optional accessories such as the MTC-30MK Marine Kit Grille, MTC-30CM ceiling-mount adapter, and MTC-30UB U-bracket provide additional mounting flexibility for specific installation needs.

With its high power handling, excellent sound quality, weather-resistant design, and versatile installation options, the JBL Control 31-WH is the ideal solution for a wide variety of high-output audio applications, whether indoors or outdoors.
