JBL Control 328CT 8" Coaxial Ceiling Loudspeaker with Transformer

8" Coaxial Ceiling Loudspeaker with HF Compression Driver - 70V/100V (Each)

8" Coaxial Ceiling Loudspeaker with HF Compression Driver
Control 328CT has been engineered from the ground up to deliver exceptional next-generation performance in a coaxial point source design ceiling loudspeaker.

Control 328C and Control 328CT have 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.

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 328C and Control 328CT are easy to install. 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-300RG8 round grille is designed to suit high-end venues, offering a simple, elegant appearance that fits into a wide variety of decors.

The optional MTC-300BB8 one cubic foot backcan is made of extra-thick 16 gauge steel and the top is lined with 1/2" medium density fiberboard.

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.

To ensure long life and reliability, Control 328C/CT passes JBL's 100-hour torture power test, the toughest standard in the industry.
