Key Features
The white pair of 2-way, 8″ JBL Professional Control 28-1-WHT are designed for background or foreground applications. Featuring weather-protected circuitry, the Control 28-1L can be used indoors or outdoors and are well suited for retail stores, restaurants, health clubs, theme parks, educational facilities, hospitality, music cafes, leisure venues, and anywhere where high-quality, high-output indoor/outdoor foreground/background music (and/or paging) speakers are required. The speakers feature JBL’s proprietary InvisiBall mounting hardware, which allows for installation through a hidden access point behind its logo badge.
The Control 28-1L require 120W (240W program) at 8 Ohms to power the 8″ woven fiberglass woofer and 1″ PEI diaphragm tweeter, which combine for a frequency response of 62 Hz to 16 kHz and a max SPL of 118 dB peak. Connections to the speaker are screw-down terminal strips with a zinc-plated copper and nickel-plated metal screws and washers. The JBL Control 28-1L includes the InvisiBall wall-mounting system and a hex key.
