The Control 28 offers a rich sonic character making it 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 patented InvisiBall mounting hardware is included in each system and makes short work of permanent installation. The InvisiBall mounting method adds the bene?t of vertical rotation of up to 37ﾰ off-axis and horizontal rotation of up to 44ﾰ offaxis. 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 ?nishes to match any decor. Weather resistance is maximized by coating the woofer cone in polypropylene and terminating its circumference in JBLﾒ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 ?lm of titanium for added rigidity and endurance against sun, salt and moisture. Zinc plated grilles resist rusting in the harshest conditions. Available in black (Control 28) and white (Control 28-WH).
