The JBL Control 28-1 is a high-output 8-inch two-way commercial speaker designed for professional indoor and outdoor sound systems. It combines high-fidelity audio, wide 100° x 100° coverage, flexible installation, and both 8-ohm and 70V/100V operation, making it a versatile choice for background music, foreground music, and paging applications.
With an 8-inch woven-fiberglass woofer and 1-inch PEI diaphragm tweeter, the JBL Control 28-1 delivers clear, full-range sound with a frequency range extending from 45 Hz to 20 kHz. Its 91 dB sensitivity and up to 112 dB maximum SPL make it suitable for installations where consistent, high-output audio coverage is important.
The Control 28-1 is designed for commercial audio applications including restaurants, retail stores, hospitality venues, health clubs, educational facilities, theme parks, music cafes, leisure facilities, and other professional sound installations. Its weather-resistant construction also makes it suitable for covered outdoor areas and demanding environments when properly installed.
JBL Control 28-1 8-Ohm and 70V/100V Operation
One of the key advantages of the JBL Control 28-1 is its flexible power configuration. In direct 8-ohm operation, the speaker provides 120 watts of continuous pink-noise power handling and 240 watts of program power. For distributed commercial audio systems, the built-in transformer provides 70V taps at 60W, 30W, 15W, and 7.5W, along with 100V taps at 60W, 30W, and 15W.
This flexibility allows the Control 28-1 to be used in both conventional low-impedance speaker systems and 70V/100V commercial distributed audio systems, making it a practical solution for installations with multiple speakers and longer cable runs.
Wide 100° x 100° Sound Coverage
The JBL Control 28-1 provides 100° x 100° coverage, helping deliver consistent sound over a broad listening area. The wide dispersion can help reduce the number of speakers required for some installations while maintaining even coverage throughout the space. JBL lists the speaker's sensitivity at 91 dB (1W/1m) and maximum SPL at 112 dB average, 118 dB peak under its specified test conditions.
Built for Commercial Indoor and Outdoor Applications
The Control 28-1 features a rugged enclosure and weather-resistant transducers for use in demanding commercial environments. The standard speaker is rated IP-44, while the optional MTC-28WMG-1 WeatherMax grille and compatible protective covers can increase environmental protection to IP-55 when installed according to JBL's requirements. JBL also specifies resistance to humidity, salt spray, temperature, and UV exposure.
For outdoor installations, proper placement, protection, and installation are important to ensure the speaker is used within its environmental rating.
Flexible Mounting with InvisiBall
Installation is simplified with JBL's included InvisiBall wall-mounting system. The mounting system allows the speaker to be aimed vertically and horizontally while keeping the mounting hardware largely hidden behind the speaker grille/logo area.
For installations requiring additional mounting flexibility, the JBL MTC-28UB-1 U-bracket is available as an optional accessory. JBL also offers the MTC-28WMG-1 WeatherMax grille and MTC-28/25CM ceiling-mount InvisiBall adapter for compatible installations.
