JBL MS-12SD4 12 inch Dual Voice Coil Sub-Woofer 1800W is an Audio muscle with flexibility
JBL MS-12SD4 12 inch Dual Voice Coil Sub-Woofer 1800W will add serious muscle to any car audio system. But the MS-12SD4 is also about flexibility, offering you the exact wiring options you need to build the car audio system of your dreams. A 4-ohm, dual voice-coil design, the MS-12SD4 lets you wire the two voice coils in parallel (to get more output from your amplifier) or in series (to bridge your amp for adding a second sub) or . . . well, you tell us. The system design possibilities are almost unlimited – and the sound is exceptional. Featuring a rigid laminated polypropylene cone, fabric surround and vented polepiece, the MS-12SD4 is optimized for sealed and vented enclosures with a vented, cast-aluminum basket that dissipates heat effectively to play louder and longer without power compression. Power, accuracy and dynamic range are what set JBL professional loudspeakers apart, and the JBL MS-12SD4 subwoofer has been engineered to the same exacting standards.
