``The sound sounds as one'' An unprecedented sense of unity in sound created by coaxial.

Z900PRS was born from PIONEER as a new challenge. The most distinctive feature is the adoption of the CST (Coherent Source Transducer) driver, which is the core technology of Pioneer's high-end audio brand TAD (Technical Audio Devices). This is a technology that eliminates phase disturbances by starting the tweeter and mid-range sounds from the same point. This produces a smooth tone with a sense of unity. Although it is large, it can also be attached and fixed to a dash board or embedded in a pillow (85,800 yen including tax).
