The JBL Control 321CT coaxial speaker has been engineered from the ground up to deliver exceptional next-generation performance in a coaxial point source design ceiling loudspeaker with pre-attached 60-Watt, 70V/100V Multi-Tap Transformer. The low-frequency cone 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 speakers. The result is a coaxial speaker with extremely consistent 90º coverage on a broadband basis. The Control 321CT is easy to install, innovative EZRail™ feature built into the metal baffle temporarily holds one side of the speaker baffle in place until the installer can affix the baffle to the backcan with screws. The removable multi-pin locking connector, with secure screw-down terminals, allows for pre-wiring the input wires for easy clip-on convenience during installation.
