General Description: Technical Specifications:
The Electro-Voice® Zx3 is the new standard of no compromise audio
performance and versatility in a simple to use, compact package.
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 heatsink 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.
Two coverage patterns are available; 60° x 60° coverage for long-throw
and cluster applications, 90° x 50° coverage for wider coverage or shorter
distances.
The Zx3 is equipped with two anchor plates for rigging with single studfittings, along with two more possible anchor plate attachment points on
the bottom. For permanent suspension or attaching brackets, the Zx3
also has two M8 inserts on the top and bottom, two under the handle,
and one on the back of the enclosure, for a total of 7. All versions are
available in black or white.
