JBL Control 28

JBL Control 28 zvučnici

The Control 28 offers a rich sonic character making it a perfect choice for restaurants, health clubs, under balcony, outdoor theme & water parks, or other applications where foreground/background music and paging are required.The patented InvisiBall mounting hardware is included in each system and makes short work of permanent installation. The InvisiBall mounting method adds the benefit of vertical rotation of up to 37° off-axis and horizontal rotation of up to 44° offaxis.Because InvisiBall adjustments are made through a hidden access behind the logo badge, the grill never needs to be removed and there exists a high degree of theft deterrence as well.The Control 28 readily accepts a variety of paints and finishes to match any decor.Weather resistance is maximized by coating the woofer cone in polypropylene and terminating its circumference in JBL’s WeatherEdge™, a seamless,rubberized extension of the woofer surround that provides added protection to critical transducer elements. The polycarbonate tweeter diaphragm is reinforced with a thin film of titanium for added rigidity and endurance against sun, salt and moisture. Zinc plated grilles resist rusting in the harshest conditions.
