MRC Aramid-Fiber Matrix Woofer
The main speaker diaphragm on the XS-690ES is crafted from Sony's unique Mica Reinforced Cellular (MRC) material. This rigid but lightweight driver allows for a much more precise response than conventional driver materials, for smoother and more natural sound characteristics.
Optimal formulation
Embedding MRC in a unique matrix with aramid fibers 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.
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.
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.
Progressive Height Rate Spider
The acoustically optimized spider allows for higher power handling and airflow, with a profile designed for more rapid and precise cushioning of the speaker cone.
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 40 kHz.
