Lightweight Rigid Cellular Aramid Fiber Matrix Woofer

The main speaker diaphragm on the XS-690ES is crafted from Sony's unique Lightweight Rigid Cellular material, formerly known as MRC. The latest generation compound has been further optimised alongside mechanical driver improvements, to deliver an even wider frequency response and smoother, more natural sound characteristics.

Optimal formulation

Embedding in a unique matrix with aramid fibers suppresses diaphragm resonance and minimises 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.

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.

Tweeter to hit the high notes

Compatible with High-Resolution Audio, a soft dome tweeter diaphragm is directly attached on the voice coil, designed to cover your music's ultra-high ends, with a frequency range extending up to 40kHz.

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.

Five-beam Frame Structure & 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.
