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

$855.00

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 for a high degree of weather capability and pure butyl rubber surround for clean sound quality, a high-temperature fiberglass voice coil former for high sensitivity, high output capability and stable performance under long-term high power working conditions. The optimized cone geometry provides for 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.

About the JBL CONTROL 31 Two-Way High-Output Indoor-Outdoor Monitor Speaker

The JBL CONTROL 31 is a two-way, high-output monitor speaker engineered to deliver robust and reliable sound reinforcement for a wide spectrum of professional indoor and outdoor applications. Designed to serve as a versatile audio solution, this model combines an 8-inch low-frequency driver with a 1-inch titanium diaphragm compression driver to produce a powerful, full-range sound with excellent clarity and projection. Its durable, weather-resistant construction allows it to perform consistently in challenging environments, making it suitable for use as a stage monitor, main speaker for small venues, or a high-output source for foreground music in outdoor hospitality areas, transportation hubs, and athletic facilities. The speaker's balanced sonic character ensures both musical fidelity and exceptional speech intelligibility, which is critical for live performances and public address scenarios.

Built to endure the rigors of professional use, the enclosure is constructed from UV-stabilized, high-impact polypropylene and features a corrosion-resistant, powder-coated steel grille that provides protection against moisture, physical impact, and prolonged sun exposure. This robust design ensures long-term reliability in both fixed installations and portable setups where equipment is subject to variable weather conditions. The speaker's high sensitivity and substantial power handling enable it to achieve significant sound pressure levels with low distortion, providing ample headroom for dynamic audio content and ensuring that the sound remains clean and articulate even at high volumes.

The CONTROL 31 is designed for flexible deployment with multiple integrated mounting points, allowing it to be easily configured as a stage wedge, pole-mounted on a stand, or installed on a wall or ceiling. Its versatile input panel includes dual NL4 SpeakON connectors for daisy-chaining multiple speakers and secure, reliable connections. By merging high-output performance, environmental durability, and flexible installation options, the JBL CONTROL 31 provides audio professionals with a dependable and powerful speaker solution capable of delivering high-impact sound in virtually any setting, from controlled indoor stages to exposed outdoor environments.
