JBL Professional","The Control® 28 is the largest of JBL Professional's Control Contractor Series indoor\/outdoor loudspeakers. Its rich sonic character makes the Control® 28 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 unique and global patent pending 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 degree off-axis and horizontal rotation of up to 44 degree off-axis. 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 erminating 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.
