The JBL Control 23-1 is a compact yet powerful two-way speaker designed for diverse indoor and outdoor applications where high-quality audio and aesthetic versatility are required. Featuring a 3-inch speaker system, the Control 23-1 delivers rich sound with wide coverage and consistent dispersion, making it suitable for environments such as retail stores, restaurants, health clubs, theme parks, educational facilities, hospitality venues, music cafes, and leisure settings.
One of the standout features of the Control 23-1 is its innovative InvisiBall mounting system, which simplifies permanent installation. This unique mounting hardware allows for both vertical and horizontal rotation adjustments without the need to remove the grille, thanks to hidden access behind the logo badge. This design not only facilitates ease of installation but also offers enhanced theft deterrence. Additionally, integrated M6 mounting points support optional U-brackets, adding flexibility to installation options.
The Control 23-1’s design ensures both durability and exceptional sound quality. The low-frequency driver utilizes a woven fiberglass cone combined with a pure butyl rubber surround, providing robust performance and weather resistance. The high-temperature Kapton™ voice coil former and voice coil wire contribute to excellent sensitivity and power handling, ensuring reliable performance even in long-term high-power scenarios. JBL’s WeatherEdge™ technology, a seamless rubberized extension of the woofer surround, adds an extra layer of protection to critical transducer components.
The speaker’s cone geometry is optimized to deliver smooth frequency response and consistent off-axis performance, supported by an FEA-optimized motor construction and linear suspension spider that help reduce harmonic distortion. For the high-frequency driver, a low-viscosity ferro-magnetic fluid enhances voice coil cooling, which extends the speaker’s power handling capabilities. The softened PEI diaphragm ensures pure and smooth high-frequency sound, while the lightweight Kapton™ voice coil former improves durability and extends high-frequency response.
The Control 23-1 is built to withstand harsh environmental conditions. Its cabinet is constructed from high-impact polystyrene (HIPS) and painted with UV-resistant paint on the white version (-WH) to prevent fading. The grille is highly zinc-plated and coated with durable TGIC polyester powder coating for rust resistance. For particularly challenging environments, the optional MTC-23WMG-1 WeatherMax™ grille can be used to protect against driving rain. The speaker’s weather-capable screw-down terminals and optional MTC-PC2 and MTC-PC3 panel covers provide additional protection, ensuring a watertight seal when used with appropriately rated cables.
The Control 23-1 is capable of handling 50 watts of continuous pink noise (100 watts program), with a maximum SPL of 103 dB, thanks to its high sensitivity and power handling capacity. It also includes a built-in 15-watt 70V/100V multi-tap transformer, allowing for seamless integration into distributed speaker lines. This makes the Control 23-1 a versatile choice for both foreground and background music applications, as well as paging needs.
In summary, the JBL Control 23-1 combines high performance, durability, and installation flexibility, making it a superior choice for a variety of demanding audio environments.
