JBL Control 28-1L Indoor/Outdoor Speaker(Pair)

About: JBL Control 28-1L Indoor/Outdoor Speaker(Pair)

The Control 28-1L is a two-way 8” speaker with rich sonic character, wide coverage, consistent coverage, versatile mounting, and a contemporary high-design look that fits into a wide range of decors, This makes Control 28-1L an excellent choice for a wide variety of applications, including retail stores, restaurants, health clubs, theme parks, educational facilities, hospitality, music cafes, leisure venues, and anywhere where a top quality high-output indoor/outdoor foreground/ background music (and/or paging) speaker is required.

The unique InvisiBall mounting hardware is included in with each system, making short work of permanent installation. The InvisiBall mounting method provides a high degree of both vertical and horizontal rotation, and because InvisiBall adjustments are made through a hidden access behind the logo badge, the grille never needs to be removed and there exists a high degree of theft deterrence as well. Integrated M6 mounting points for an optional U-bracket adds to the installation versatility.

The LF driver’s woven fiberglass cone provides durability and weather capable performance. The light weight high temperature fiberglass voice coil former and high temperature voice coil wire ensures stable performance under long-term high-power working conditions while also providing high sensitivity and high power capability. The pure butyl rubber surround delivers clean sound and ruggedness, while terminating its circumference in JBL’s WeatherEdge, a seamless, rubberized extension of the woofer surround that provides added protection to critical transducer elements. Cone geometry is optimized for smooth frequency response and good off-axis performance, while an FEA optimized motor construction and linear suspension spider helps to lower harmonic distortion.

The HF driver’s low viscosity ferro-magnetic fluid increases voice coil cooling for higher long-term power handling. The PEI diaphragm delivers a smooth high frequency sound quality. A light weight Kapton voice coil former increases durability while providing better high frequency response extension. All these factors also contribute toward making the driver especially rugged for outdoor and other stressful applications.

In addition to the driver designs contributing toward a high degree of weather resistance, the cabinet provides excellent endurance against sun, salt and moisture. Grilles are heavily zinc-plated and finished in a tough, high-grade powder coating for rust resistance, and optional MTC-28WMG-1 WeatherMax grilles are available for especially difficult environments and to break up driving rain. Connection is made via weather-capable screw-down terminals, and the optional MTCPC2 and MTC-PC3 panel covers are available to protect the terminal compartment, providing a water-tight sealed gland-nut entrance (when used with round-jacketed cable within the specified diameter range).

The frequency response is extremely smooth, resulting in a very natural sound character, and the response extends down to 45 Hz, providing strong bass capability. The system is capable of handling 120 Watts continuous pink noise (240 Watts program). The combination of high sensitivity and power handling provides high maximum SPL of 112 dB.

The Control 28-1L readily accepts a variety of paints and finishes to match any décor. Available in black or white (-WH).
