JBL Control 321CT 12 Inch Coax Ceiling Speaker With Transformer

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 90Ý coverage on a broadband basis.

Component features include a Kevlar reinforced 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 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 optionalMTC-300SG12 square grille is designed to suit high-end venues, offering a simple,elegant appearance that fits into a wide variety of decors.

The optional, best-in-class, MTC-300BB12three cubic foot back can is made of extra-thick16 gauge steel and lined with 1/2″ medium density fiberboard to provide the performance of a top quality wood loudspeaker cabinet in a metal back box form factor.

The transformer version Control 321CTcomes with a pre-attached top quality, low saturation 68 Watt multi-tap transformer for us eon 70V or 100V distributed speaker lines.
