Lightweight Rigid Cellular 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 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.
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.
