JBL Control 312CS 12 400W In-Ceiling Subwoofer Driver
The JBL Control 312CS is a passive 12 in-ceiling subwoofer driver designed to deliver reliable low-frequency reinforcement for foreground music systems in a variety of venues such as boardrooms, retail stores, and restaurants. When driven by an 8-Ohm power amplifier (available separately), this subwoofer is capable of a 400W long-term power capacity. The Control 312CS features a durable 12 woofer with a Kevlar-reinforced cone and a 3 voice coil, and boasts a frequency response of 34 Hz to 3.5 kHz.A removable locking connector offers screw-down terminals for input and loop-thru output connections. Installation is simplified via the built-in EZRail, which holds the pre-attached baffle in place until it is affixed to a backcan (available separately). The Control 312CS is intended for use with systems utilizing active external crossovers and separate subwoofer amplification.
Ideal for reinforcing full-range speakers for foreground music systems
For use with 8-Ohm power amplifier
Low-distortion 12 woofer with Kevlar-reinforced cone and 3 voice coil
400W (1000W peak) long-term (for two hours) system power rating
Removable locking connector with screw-down terminals for easy wiring of the input and loop-thru output
Pre-attached ported baffle equipped with EZRail for simplified backbox installation
Low-frequency extension down to low 30 Hz (-10 dB)
Compatible with MTC-300SG12 grille, and MTC-300BB12 backbox (both available separately)
