z is a compact high output 3-way line array speaker. It is equipped with a long thrown13 inch ultra-low distortion woofer. It has higher power and stronger bass than that of a 12" one while it requires a much smaller size cabinet than that of a 15" one. It achieves a much stronger bass effect by the ingenious design of the cabinet itself. The speaker is suitable for a variety of venues that requires high power and dynamic output.

z-b is a 21-inch high-output subwoofer. It features a 5-inch voice coil,1600W continuous power, strong low-frequency response and huge dynamic headroom. The optimized design of the cabinet with compressed low-frequency processing provides a tight and accurate bass response, making it very suitable for mobile or fixed installation applications. The integrated suspension system allows fast and easy flying or ground stacking of the speakers.

The mid and hi section employs a two-way coaxial driver with two concentric ring diaphragms. Each diaphragm covers a smaller frequency range to improve power processing capacity, high dynamics and very low distortion. It features high fidelity and high sensitivity. The larger annular diaphragm covers the mid-frequency range with a smooth linear response. Ultra-light ring diaphragm for high-frequency range provides excellent transient response and high efficiency. Tailored for a carefully designed Waveguide Horn, excellent medium and high-frequency directivity control can be achieved.
