JBL Professional","Control 328CT is a high power 200 mm (8 in) coax speaker with a 60W multi-tap 70V\/100V transformer, 250 watts, 45 Hz - 18 kHz.","Control 328C has been engineered from the ground up to deliver exceptional next-generation performance in a coaxial point source design ceiling loudspeaker. The combination of the low frequency cone and the shaped mounting baffle performs as a true 12 inch (300 mm) diameter waveguide for the high frequencies. A unique metal throat transitions seemlessly to the horn to eliminate high frequency beaming which is common among this category of speaker. The result is a coaxial speaker with wide, extremely consistent 120° coverage on a broadband basis. The transformer version Control 328CT comes with a pre-attached top quality, low saturation 60 Watt multi-tap transformer for 70V\/100V distributed speaker lines.

JBL Professional","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 balcony, outdoor theme & water parks, or other applications where foreground\/background music and paging are required. 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 degree off-axis and horizontal rotation of up to 44 degree 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® 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 erminating 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.
