About The Product
Lightweight Rigid Cellular Aramid Fibre Matrix Diaphragm
The diaphragms for the woofer and mid-range driver are crafted from Sony’s unique Lightweight Rigid Cellular material, formerly known as mica reinforced cellular. The latest generation compound has been further optimized alongside mechanical driver improvements to deliver an even wider frequency response and smoother, more natural sound characteristics.
Shallow mid-range driver
The newly-developed mid-range driver is driven via a compact but incredibly powerful neodymium magnet. The result is a shallower basket, designed to perform even in confined spaces and challenging installations.
Optimal formulation
Embedding in a unique matrix with aramid fibres suppresses diaphragm resonance and minimizes distortion, not only in the lows but also in the mid and higher frequencies. The result is sound that is powerful at all frequencies and uncommonly clean, even at high volume.
