About JBL

The Control 28T is the largest of JBL Professional's Control Contractor Series indoor/outdoor loudspeakers. Its rich sonic character makes the Control 28T 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 Control 28T can be used in either 70.7V or 100V distributed-line sound systems. Taps are provided at 60W, 30W and 15W (plus a 7.5W tap for use on 70.7V systems only).

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 deg. and horizontal rotation of up to ±44 deg.. Because InvisiBall adjustments are made through a hidden access behind the logo badge, the grill never needs to be removed, while providing a high degree of theft deterrence as well.

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.
