JBL Control 321CT 12" 2-Way 250W Coaxial 70V/100V Ceiling Speaker

JBL Control 321CT Overview

The JBL Control 321CT is a passive 12" coaxial ceiling speaker featuring a multi-tap transformer, designed for clear voice amplification and foreground music in spaces such as waiting areas, offices, retail environments, and restaurants. Equipped with a low-saturation transformer, it is compatible with 70V/100V amplifiers (sold separately) and offers a continuous power rating of 250W, with a peak capacity of 1000W.

This two-way speaker includes a rugged 12" Kevlar-reinforced cone paired with a titanium-diaphragm compression driver, delivering an extended frequency range from 47 Hz to 16 kHz. The cone also functions as a waveguide, providing consistent 90° coverage, while the integrated crossover network ensures accurate frequency distribution between components. Installation is simplified with a removable locking connector featuring screw-down terminals, allowing easy wiring at the selected power tap.
