Electro-Voice ZX1i-90

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 system 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.

All Zx1i "t" versions use a special circuit that, when in transformer mode, re-configures the network 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.
