JBL Control 28-1L - 120W 8-inch Passive 2-Way IP44-Rated 70V/100V Surface-Mount Loudspeaker with 100 x 100-Degree Coverage and 8-Ohm Impedance in Black Finish

The JBL Professional Control 28-1L is a high-performance, passive 2-way surface-mount loudspeaker designed to deliver exceptional sound quality for both indoor and outdoor environments. This 8-inch speaker features a sleek, contemporary design and is engineered to meet the demands of high-output applications in a variety of settings such as retail stores, restaurants, theme parks, educational facilities, hospitality venues, music cafes, and leisure environments. Whether used for background or foreground music, as well as paging systems, the Control 28-1L excels in delivering clear, powerful sound with broad coverage and consistent performance.

The speaker is equipped with an 8-inch woofer that features a woven fiberglass cone and a pure butyl rubber surround, ensuring long-term durability and excellent sound reproduction even in high-humidity environments. The woofer is further protected by JBL's WeatherEdge technology, a seamless rubberized extension of the surround that safeguards critical transducer elements against moisture and weathering. The high-frequency response is provided by a 1-inch PEI diaphragm tweeter with fluid cooling, designed to deliver smooth and clear high frequencies with low distortion. Together, the woofer and tweeter create a full-range sound profile, with the system capable of producing a wide frequency response from 62 Hz to 16 kHz. The speaker can handle up to 240 watts of continuous program power and delivers a maximum SPL of 118 dB peak, making it well-suited for larger spaces that demand high-output sound.

The Control 28-1L offers a broad 100° x 100° coverage angle, ensuring even sound distribution across large areas. Its coaxial design allows for excellent off-axis performance, minimizing the need for additional speakers while ensuring uniform coverage. This makes it an ideal solution for reducing installation complexity and cost without sacrificing sound quality. Additionally, the high directivity index (DI) of 8.3 dB and directivity factor (Q) of 7.3 contribute to its ability to maintain sound clarity and intelligibility, even in acoustically challenging environments.

One of the standout features of the Control 28-1L is its versatility in installation. The speaker comes with JBL's proprietary InvisiBall mounting system, which facilitates quick, secure, and flexible installation with both vertical and horizontal rotation. The InvisiBall system also provides theft deterrence, as the grille remains securely attached and does not need to be removed for mounting adjustments. The speaker includes an integrated M6 mounting point for an optional U-bracket, further enhancing its adaptability for different installation needs. Additionally, the Control 28-1L is IP44-rated, ensuring protection against dust and water splashes, making it suitable for both indoor and outdoor installations.

For ease of installation, the speaker comes with a variety of accessories including a C-shaped support backing plate, two tile support rails (for use with both 2 x 4 ft or 600 x 1200 mm tiles), a cutout template, a paint shield, and a removable locking wiring connector. The Control 28-1L is also compatible with optional accessories like the MTC-28UB-1 U-bracket, MTC-28WMG-1 WeatherMax grille for enhanced weather protection, and the MTC-28/25CM ceiling-mount InvisiBall adapter for installations that require overhead mounting.

Whether used in commercial or residential settings, the JBL Professional Control 28-1L provides superior audio performance, rugged weather-resistant design, and versatile installation options to meet the demands of any high-output sound system. Available in black or white finishes, the Control 28-1L is designed to blend seamlessly into a wide range of environments while delivering premium sound quality.
