HARMAN 12" JBL Ceiling Subwoofer

Control 312CS is an excellent addition to JBL Control 321, 322 and 328 loudspeaker systems, or any full range loudspeaker system that requires extended bass response. The 300 mm (12 inch) driver features a Kevlar-reinforced low frequency cone for reliability, well-damped surround, extended excursion capability, high temperature 75 mm (3 in) voice coil and reduced distortion through saturated gap magnet geometry.
The Control 312CS is easy to install. The innovative EZRail feature built into the metal baffle temporarily holds one side of the speaker baffle in place until the installer can affix the baffle to the backcan with screws. 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-300SG12 square grille is designed to suit high-end venues, offering a simple, elegant appearance that fits into a wide variety of décors. The optional, best-in-class, MTC-300BB12 three cubic foot backcan is made of extra-thick 16 gauge steel and lined with 12 mm (½ in) medium density fiberboard. This provides the performance of a top quality wood loudspeaker cabinet in a metal backbox form factor.
Control 312CS is intended for systems utilizing an external active subwoofer crossover and separate amplifier channel for the subwoofer loudspeaker(s). To ensure long life and reliability, Control 312CS passes JBL's 100-hour torture power test. Nobody in the industry has more demanding reliability standards.
