Elevate your sound
Enjoy deep and rich bass sound with this Mobile ES 12-inch 4-ohm subwoofer. With unique mechanical driver improvements and a rigid but impressively light-weight diaphragm, you will enjoy clear powerful low end, for a great in-car listening experience.
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.
