JBL CONTROL 321C Premium 12” Coax Ceiling Loudspeaker
True-Broadband 90º Coverage. 250 Watts, 34 Hz to 18 kHz Frequency Response, 94 dB Sensitivity. 2412H Compression Driver. 14.4” Square Ported Baffle x 8.8” Deep. EZ-Rail™ For Ease of Installation.
Control 321C and Control 321CT have been engineered from the ground up to deliver exceptional next-generation performance in a coaxial point source design ceiling loudspeaker. 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 speaker. The result is a coaxial speaker with extremely consistent 90º coverage on a broadband basis.
Component features include a Kevlarreinforced low frequency cone for reliability, well-damped surround for smooth frequency response, high temperature voicecoil and a reduced distortion design through saturated-gap magnet geometry. The high frequency driver features a pure titanium diaphragm for high sensitivity and long life, with diamond surround for resonance control and FerroFluid™ for increased power handling.
The Control 321C and Control 321CT are easy to install. The innovative EZRail™ feature built into the metal baffl e temporarily holds one side of the speaker baffl e in place until the installer can affi x the baffl e 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. The clean, contemporary look of the optional MTC-300SG12 square grille is designed to suit high-end venues, offering a simple, elegant appearance that fi ts into a wide variety of décors.
The optional, best-in-class, MTC-300BB12 three cubic foot backcan is made of extra-thick 16 gauge steel and lined with 1/2” medium density fiberboard to provide the performance of a top quality wood loudspeaker cabinet in a metal backbox form factor.
The transformer version Control 321CT comes with a pre-attached top quality, low saturation 60 Watt multi-tap transformer for use on 70V or 100V distributed speaker lines. To ensure long life and reliability, Control 321C/CT passes JBL’s 100-hour torture power test. Nobody in the industry has more demanding reliability standards.
