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

The JBL Professional Control 31 is a high-performance, 250W passive 3-way surface-mount loudspeaker designed for both indoor and outdoor applications where robust audio output and weather resistance are essential. This 10-inch loudspeaker offers exceptional sound quality with extended bandwidth, smooth frequency response, and well-controlled, defined coverage, making it ideal for use in a wide range of environments including retail stores, stadiums, theme parks, and public venues. The Control 31 provides a versatile solution for both foreground and background music, as well as paging, with its sleek, professional design and high-fidelity performance.

At the heart of the Control 31 is a carefully engineered 10-inch low-frequency (LF) driver featuring a woven fiberglass cone, combined with a 2-inch voice coil on a high-temperature fiberglass former for optimal performance. The driver is designed for high sensitivity and power handling, ensuring that the speaker can perform well even in high-demand situations. The LF driver is complemented by a high-output, fluid-cooled compression driver with a 1-inch diaphragm made from high-temperature polymer, offering excellent high-frequency clarity and extended response. The coaxial component of the LF and HF drivers ensures that the sound remains coherent and well-blended across the frequency spectrum, delivering exceptional audio across the entire listening area.

The speaker's 110° horizontal x 110° vertical coverage pattern ensures even and consistent dispersion, no matter how the speaker is oriented. The horn is symmetrical and rotatable, allowing users to install the Control 31 in both vertical and horizontal positions while maintaining the same coverage angle. This flexibility is ideal for installations where precision and flexibility are required, such as stadiums or multi-use spaces. Additionally, the speaker's highly controlled frequency response and minimal harmonic distortion ensure that the audio remains natural and clear, even at high output levels.

The Control 31 is designed for both 70V and 100V distributed systems, making it suitable for a variety of large-scale installations. The included high-quality transformer allows for minimal insertion loss and reduced saturation, while the 8Ω bypass option enables the use of multiple speakers on a single loudspeaker line when required. The speaker's maximum SPL of 123 dB short-term and 117 dB long-term makes it well-suited for environments where high output is necessary without sacrificing audio fidelity.

Weather resistance is a key feature of the Control 31. The woofer is housed in a rugged, rear-loaded basket that minimizes exposure to environmental elements, and the pure butyl rubber surround ensures durability in harsh conditions. The grille is thermoset composite-coated steel, designed to stand up to UV radiation and humidity, with an additional WeatherMax multi-layer foam backing to prevent water intrusion. The speaker's weather-resistant design makes it ideal for outdoor installations, with an IEC 529 IP-X5 rating and environmental protection that exceeds MilSpec 810 standards for humidity, salt spray, and UV exposure. An optional marine kit grille further protects the speaker in salt-air environments.

The Control 31 features JBL's exclusive SonicGuard overload protection, which helps safeguard the speaker from damage due to excessive power levels while maintaining full-fidelity sound. This protection mechanism is virtually inaudible to the listener, ensuring that the speaker delivers the best performance without any compromise. The speaker also includes a sealed input panel cover and nickel/zinc rust-resistant terminals for a secure, long-lasting connection. An MTC-PC2 sealed-entrance cover is included to further protect the speaker's terminals from environmental damage.

For installation, the Control 31 features the InvisiBall mounting system, which allows for quick and easy mounting, as well as horizontal and vertical rotation for precise aiming. The system provides up to 41° of horizontal rotation and 36° of vertical rotation (horn end inward) or 23° (woofer end inward), ensuring flexibility in positioning the speaker to meet specific acoustical needs. The optional MTC-30UB U-bracket allows for low-profile installation, especially in under-balcony applications, while attachment points for suspension offer additional mounting flexibility.

With its high power capacity, weather-resistant design, and versatile mounting options, the JBL Control 31 is an excellent choice for demanding applications where audio clarity, coverage, and durability are crucial.
