The Electro-Voice ZX1i is the new standard of no compromise audio performance and versatility in an easy to install, compact sound reinforcement package. The high-tech enclosure uses injection-molded high-impact polypropylene to make the ZX1i extremely durable. The enclosure geometry has been engineered to provide maximum rigidity and acoustic performance. The velocity compensated port design overcomes the limitation of many small cabinet loudspeakers and enables exceptional low-frequency response without vent noise. ZX1i installation is incredibly simple with the included QuickSAM mounting system. The QuickSAM is a unique, integrated mounting bracket which is virtually foolproof. It allows the installer to simply snap the speaker onto the bracket, then tighten it to the desired position. For array mounting, there is an optional array bracket kit available which allows multiple units to be mounted together for a variety of configurations. Zx1i uses a special circuit that when in transformer mode the network re-configures itself to a current actuated Hi-Pass filter at the transformer primary. It gently rolls off the lowest frequencies to maintain a safe load on the amplifier without affecting the higher (vocal) frequencies and the program continues without interruption. Low frequency current is limited through the transformer eliminating low frequency saturation. Automatic Saturation Compensation allows many speakers to be run on a distributed line with a 50Hz Hi-Pass filter before the amplifier, regardless of the number of speakers on the same line (the number of tapped watts cannot exceed the amplifier rating). With the same 50Hz Hi-Pass, 10 speakers on transformers will have the same full sound as a single speaker at 8 ohms. Two coverage patterns are available; 90 x 50 coverage for longer throw and cluster applications, 100 x 100 coverage for broad even dispersion needed in many distributed audio applications. An added benefit is horn rotation, allowing the ZX1i to be oriented either horizontally or vertically for complete coverage flexibility. The ZX1i molded polymer enclosure is inherently water resistant. The addition of a multilayer grille with hydrophobic cloth and weatherized components enable the ZX1i to perform under many environmental conditions. An optional weatherized input panel cover with a gland nut is available for additional protection. The ZX1i's long excursion, high output 8" woofer with a weatherized treated cone delivers smooth low-frequency performance with exceptional reliability. A sophisticated crossover network integrates it with the DH2005, a 1.25" voice coil true compression driver for maximum output with extended frequency response. Fullbandwidth overload protection is provided for reliable, long term operation without audible effect.
