The JBL Control 321CT is a coaxial point source design ceiling loudspeaker, equipped with a built-in 70V/100V multi-tap transformer, and featuring a 12" low frequency cone performing as a waveguide for the high frequencies. The unique metal throat provides seamless transition to the horn, eliminating any aberrant HF "beaming", and resulting in consistent 90° coverage on a broadband basis with true coaxial behavior.

Coaxial ceiling speaker with 1" HF compression driver and consistent 90° broadband pattern control
Built-in 70V/100V multi-tap transformer; 7.5W/15W/30W/60W 70V taps, 15W/30W/60W 100V taps
12" Kevlar-reinforced cone with 2" voice coil
250-watt power handling with high sensitivity and high SPL capability
Advanced high-slope crossover network for constant coverage and natural midrange
Baffle equipped with EZRail(TM) feature, holds baffle in place while securing to backcan with screws
Removable multi-pin locking connector with screw-down terminals for simplified pre- or re-wiring during installation
