The Control 25T is perhaps the most versatile of JBL Professional's Control Contractor Series indoor/outdoor loudspeakers. Its robust nature makes the Control 25T a perfect choice for restaurants, health clubs, outdoor theme and water parks or other applications where foreground/background music and paging are required. The Control 25T can be used in either 70.7V or 100V distributedline sound systems. Taps are provided at 30W, 15W and 7.5W (plus a 3.7W tap for use on 70.7V systems only). 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° 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 25T 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.
