User manual ELECTRO-VOICE 423A DATASHEET

[. . . ] Moving forward, EV has raised the bar once again by introducing the ZX Series: a unique combination of incredible sonic performance, application flexibility, streamlined aesthetics, and super-light weight. The 423A and powered ZXA5 offer a range of features and a level of versatility unmatched in other 15-inch two-way loudspeakers. The relationship between enclosure and component is crucial to optimizing loudspeaker system performance. By designing and manufacturing its own components, EV ensures this critical balance is achieved in every loudspeaker that leaves the factory. [. . . ] 423A epitomizes this approach by utilizing tour grade DVX series woofers and ND2 neodymium compression drivers. Electro-Voice Components -- The Key to Performance EV is a globally renowned pioneer and leader in transducer designs for professional loudspeaker systems. The result of an ongoing multi-million dollar R&D project, the groundbreaking DVX woofer series sets a new benchmark for performance, high SPL output, and low distortion. DVX motor structure and suspension is optimized for very linear movement using state-of-the-art development tools, such as computer simulation software for dynamic finite element analysis (Dynamic FEA). Snapshots of Dynamic FEA for a high power signal (100V) for a conventional design (top) versus DVX (bottom). The changing colors in the gap indicate an extreme variation of the magnetic flux for the conventional design, while there is only slight variation with DVX. The result is a more even travel of the DVX voice coil, significantly reducing harmonic distortion. Electro-Voice DVX® Transducer Technology In conventional woofer designs, high power signals with peaks up to and beyond 100V create a wide variation in the magnetic field, disturbing the linear movement of the voice coil and resulting in audible distortion. Unique DVX motor geometry greatly reduces these changes in magnetic flux, reducing harmonic distortion up to 20dB. DVX frames are designed with integrated Forced Air Voice Coil CoolingTM. Weatherized versions feature hydrophobic grille cloth and a waterproofed input panel. Computer Optimized HF Waveguides EV designs its superior waveguides to accurately control high- and mid-frequency dispersion. To address different coverage requirements, 423A is available in two horn patterns: 90° x 50° for wider areas; 60° x 60° for longer throw applications. Both provide smooth, even response on- and off-axis. Integrated Rigging and Suspension 423A is equipped with ten M8 threaded suspension points, allowing for a wide range of rigging configurations. Single stud fittings are standard on five of these points, including top, bottom, and rear. Accessories for Added Versatility SSK-1 CB5 HA5 ZXA5 ­ Performance and Convenience ZXA5 combines the performance of DVX and ND2 with a high output dual channel integrated amplifier. ZXA5 boasts an unprecedented power-to-weight ratio, effortlessly delivering a continuous 250 watts into the HF and 1000 watts into the LF. In addition to its incredible sonic abilities, ZXA5 retains all of the functionality of the passive 423A in terms of accessories, mounting options, and multiple monitor angles. HDC-5 Protect your investment with the HDC-5 heavy duty cover, which provides portable protection and convenient storage. A corrugated plastic insert on the top of the HDC-5 allows one unit to be stacked on top of another, a feature that is especially valuable to rental companies with large inventories and minimal space.
