The Control 25 is perhaps the most versatile of JBL Professionals Control Contractor Series indooroutdoor loudspeakers. Its robust nature makes the Control 25 a perfect choice for restaurants, health clubs, outdoor theme and water parks or other applications where foregroundbackground music and paging are required. The unique 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 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 25 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 JBLs 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. - PRICED AND SOLD AS A PAIR
