Mobile ES™ 12” (30cm) 2-ohm Subwoofer Lightweight Rigid Cellular Honeycomb diaphragm for precise and powerful bass 2,000 W peak / 500 W RMS power handling Separated Notch Edge Surround for less distortion and clear soundDynamic Air Diffuser ensures efficient air circulation for smooth cone travel and coolingElevate your sound Enjoy deep and rich bass sound with this Mobile ES 12-inch 2-ohm subwoofer. With unique mechanical driver improvements and a Lightweight Rigid Cellular Honeycomb diaphragm, you will enjoy clear powerful low end, for a great in-car listening experience. Lightweight Rigid Cellular Honeycomb Subwoofer Diaphragm Lightweight Rigid Cellular(formerly known as MRC) diaphragm material is further enhanced via a honeycomb fiber structure, for unmatched rigidity and responsiveness. Enhancements over the years of diaphragm material development produced a driver 10x more rigid than conventional PP Matrix cones, for natural low-distortion sound and a wide frequency response. Separated Notch Edge Surround The woofer surround features another proprietary Sony technology, with distinctive curved notches improving the vertical amplitude symmetry, for dramatically reduced distortion and enhanced clarity. Five-beam Frame Structure and Dynamic Air Diffuser The Five-beam Frame design disperses resonance, while the integrated Dynamic Air Diffuser ensures efficient air circulation for smooth cone travel and cooling of the voice coil. Progressive Height Rate Spider The acoustically-optimized spider allows for higher power handling and airflow, with a profile designed for more rapid and precise cushioning of the speaker cone. To increase signal integrity and prevent sound interference, the lead wire from the voice coil is also sewn to the spider, reducing wire movement. Gold-plated Input Terminals Gold-plated spring terminals allow up to AWG#10 speaker cables.
