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.

Is the XS-W122ES a single or dual voice coil subwoofer?
The XS-W122ES is a single voice coil subwoofer with a nominal 2-ohm impedance.
What is the Rigid Cellular Honeycomb diaphragm?
