Sony XS-W124ES 30 cm (12 Inch) 4 Ohm Subwoofer

Honeycomb Subwoofer Diaphragm: Lightweight Rigid Cellular(formerly known as MRC) diaphragm material is further enhanced via a honeycomb fibre 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 wide frequency response.

Seperated 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.

Progressive Height Rate Spider:  The acoustically optimised 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.

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.
