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 bal- cony, outdoor theme & water parks, or other applications where fore- ground/background music and pag- ing are required.

The unique and global patent pending InvisiBall ™ mounting hard- ware 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 hor- izontal 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 deter- rence 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 cir- cumference in JBL’s WeatherEdge™, a seamless, rubberized extension of the woofer surround that provides added protection to critical transducer ele- ments. The polycarbonate tweeter diaphragm is reinforced with a thin film of titanium for added rigidity and endurance against sun, salt and mois- ture. Zinc plated grilles resist rusting in the harshest conditions.

Available in black (Control 28) and white (Control 28-WH).
