The ZX3-90 12 inch Full Range Loudspeaker is a 600-Watt, 12 inch two-way loudspeaker system. It is bi-amp or passive with a 90° x 50° horn and an integral stand mount.
 
 At its heart are the transducers. First is the DVX3121 high performance low frequency transducer. EV used advanced computer aided design techniques to create forced air, directional voice coil cooling for high power and efficiency. Finite element analysis was used to optimize the suspension and magnetic structure for long, linear travel to provide low distortion and greater LF extension. These features and details, such as forged magnetic components and special materials, provide reliability with a 500W power rating in a lightweight transducer. Next is the ND2, a 2-inch voice coil compression driver based on neodymium motor structure to allow for maximum output while reducing size and weight to a minimum. Its precision phasing plug and titanium diaphragm provide better HF performance, while the integral heat sink provides cooling for high power output.

The high tech enclosure uses injection-molded high-impact polypropylene structural foam to make the Zx3 incredibly durable. The enclosure geometry elements have been carefully designed to provide maximum rigidity and bass response. By design the Zx3 is also a perfect solution for stage monitors by allowing two angles (45° or 55°) without any additional accessories.
