The third gen compound has been further optimized alongside mechanical driver improvements, to deliver an even wider frequency response and smoother, more natural sound characteristics.
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.
