The Electro-Voice ZX1i is the standard of no
compromise audio performance and versatility in an
easy to install compact package.
The high-tech enclosure uses injection-molded
high-impact ABS resin 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. Two rotatable horn coverage patterns are
available; 90° x 50° for longer throw and cluster
applications, 100° x 100° for broad even dispersion. A
multilayer grille with hydrophobic cloth and
weatherized components allows both indoor and
outdoor use. An optional weatherized input panel
cover with a gland nut is available for additional
protection.
Installing the ZX1i is quick and easy with the included
QuickSAM mounting system. The QuickSAM allows the
installer to simply snap the speaker onto the bracket,
and then tighten it to the desired position. For array
mounting, there is an optional AB-ZE array bracket kit
which allows multiple units to be mounted together in
a variety of configurations.
The ZX1i’s long excursion, high output 8 inch 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 inch voice coil true compression
driver for maximum output with extended frequency
response. Full-bandwidth overload protection is
provided for reliable, long term operation without
audible effect.
Best overall system design practice always includes a
high-pass filter in the signal chain before the driving
amplifier to protect the loudspeaker from
over-excursion below box tuning or in the case of a
distributed constant voltage installation, to protect the
driving amplifier from the ill-effects of transformer
saturation. The ZX1i -T incorporates patented ASC
(Automatic Saturation Compensation) technology to
prevent transformer saturation at low frequencies.
Unlike typical transformer equipped loudspeaker
systems, an installation of Electro-Voice ZX1i -T
loudspeakers does not require the high-pass filter
frequency to be raised as more loudspeakers are
added to the line because the driving amplifier is
protected by ASC from saturation-induced overload,
distortion, and possible failure. Best of all, there is no
perceivable difference in sound quality between
transformer and non-transformer versions of ZX1i
loudspeakers. The same 50 Hz high-pass filter is used
for both, regardless of the number of loudspeakers on
the line.
