A 12" (300mm), high power-handling, dual voice-coil premium subwoofer

 

Premium-performance 4-ohm subwoofer.

The JBL® MS-12SD4 is a high-performance, high power-handling, dual voice-coil subwoofer using advanced materials and innovative engineering to create smooth, powerful bass in your car. The subwoofer’s dual 4-ohm voice-coil design allows for a wide variety of connection options. You can use multiple subs to add bass, as many amplifiers – particularly the JBL MS-A5001 digital signal processing amplifier – easily drive multiple subwoofers. This sub features advanced components that include rigid polypropylene cones, stitched tri-laminate surrounds, vented magnet assemblies and non-magnetic, cast-aluminum frames for minimal power compression under extended use. Its peak power handling is 1800 watts, so it can handle tremendous power. It requires very modest enclosure volumes and performs well in either a sealed or a vented enclosure design. This subwoofer is truly a premium, performance-oriented product that can deliver excellent bass in your car.
