The DS18 PRO-ZT8 is a powerful 8-inch 2-way coaxial loudspeaker engineered for true pro audio enthusiasts who demand top-tier performance in an efficient package. Unlike traditional pro audio setups that require matching separate components, the PRO-ZT8 combines a high-output midrange driver and a built-in super tweeter into one compact speaker. This coaxial design simplifies installation while delivering a full-range frequency response from 65Hz to 22KHz. With 550 watts of max power and 275 watts RMS, it blasts clean, balanced sound even at max volume. Built with a robust ferrite magnet, a Kapton-wound voice coil, and a durable steel basket, the PRO-ZT8 is ready for extreme SPL builds or any system requiring professional sound with fewer components.
