Kevlar-Reinforced Woofer for Rich Sound
The 12-inch Kevlar-reinforced woofer in the Control 321C ensures deep, resonant bass and accurate midrange frequencies. The cone doubles as a waveguide, enabling consistent high-frequency dispersion across a broad coverage area. This design ensures listeners experience clear and even sound, no matter where they are in the room.

High-Frequency Compression Driver for Crisp Detail
Featuring a pure titanium diaphragm and diamond surround, the high-frequency compression driver delivers precise and detailed highs.

Paired with a built-in crossover network, the driver ensures seamless frequency distribution for a balanced audio experience.

Consistent Broadband Coverage

Whether installed in a small office or a large retail space, this ceiling speaker minimizes dead zones and delivers an immersive audio experience. Its metal throat transitions smoothly to the horn, eliminating high-frequency beaming and ensuring natural sound reproduction.

Simplified Installation with EZRail System
The Control 321C is equipped with JBL’s EZRail system, which holds one side of the baffle in place during installation, freeing up the installer’s hands for precise adjustments. A removable locking connector with screw-down terminals allows for pre-wiring of inputs, making installation faster and more convenient. It is compatible with the MTC-300SG12 grille and MTC-300BB12 backbox, both sold separately.
