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 (2) 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.

System overview

Architectural and Engineering Specifications:

The loudspeaker shall be a two-way system consisting
of one (1) 8 inch (102 mm) low-frequency transducer,
a 1.25 inch titanium diaphragm true high frequency
compression driver with rotatable horn and a
frequency dividing network installed in a vented
enclosure. The network shall include a full-range
passive limiter for total system protection. The high
frequency compression transducer shall drive a horn
to evenly cover a pattern of either 90° by 50° or
100° by 100°. The horn shall be rotatable to allow for
horizontal or vertical mounting of the cabinet. The
enclosure shall be molded of high impact ABS resin.

The finish shall be a paintable black or white. The
grille shall be zinc plated, powder coated for corrosion
resistance, and equipped with both hydrophobic cloth
and acoustic foam. The loudspeaker position shall be
adjustable over a range of 100° horizontally and 45°
vertically.
The support bracket shall be low profile and integral
with the enclosure. The bracket shall allow for a quick
snap fit mounting of the speaker enclosure for
placement before securing. The speaker terminals
shall include a 4-pin removable Phoenix style
connector to allow for signal pass through. The system
shall be weather resistant to MIL Spec 810 and IEC
529 test conditions.
The loudspeaker shall be available with a 100 watt
transformer for 70 or 100 volt operations. The speaker
shall have ASC for protection against transformer
saturation overload. There shall also be an 8 ohm
bypass position on the wattage selector switch to
enable 8 ohm operation from these models.
The loudspeaker system shall meet the following
performance criteria: Power handling, 200 watts long
term program using IEC268-5 shaped pink noise;
Frequency response, 48 Hz–20 kHz (-10 dB from rated
sensitivity); Pressure sensitivity, 94 dB at one (1) watt,
60 Hz–20 kHz at one (1) meter; Impedance, 8 ohms
nominal, 6 ohms minimum. The enclosure shall be 18
inch (451 mm) high, 11 inch (282 mm) wide, 10 inch
(263 mm) deep. Net weight shall be 18.5 lb (8.4 kg)
for non-transformer versions and 23.0 lb (10.4 kg) for
transformer versions.

Caution!

This Electro-Voice loudspeaker should be sus-

pended overhead only in accordance with the

procedures and limitations specified in the

User’s Manual and possible manual update

notices. This system should be suspended

with certified rigging hardware by an author-

ized rigging professional and in compliance

with local, state, and federal overhead sus-

pension ordinances.
