Despite the inherent challenges of horizontal mounting, the CX 690 maintains excellent tonal balance, broad frequency response, and robust power handling, ensuring rich lows, detailed mids, and clear highs across all genres.

Whether upgrading a factory system or building a full aftermarket setup, the CX 690 offers the versatility and musicality Hertz is known for—without compromise.
