XS-690ES | Mobile ES^™ 6 x 9” (16 x 24 cm) 2-Way Coaxial Speakers

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 optimized alongside mechanical driver improvements, to deliver an even wider frequency response and smoother, more natural sound characteristics.

Embedding 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.
