Speaker system JBL Control 321C

JBL Control 321C and Control 321CT have been engineered from the ground up to deliver exceptional next-generation per- formance 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 frequen-cies. 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 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. The clean, contemporary look of the op- tional MTC-300SG12 square grille is designed to suit high-end venues, offering a simple, elegant appearance that fits 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 ½” medium density fiberboard to provide the performance of a top quality wood loudspeaker cabinet in a metal backbox form factor.
