Description
The new Peavey ILS™ 1294H
(horizontal) loudspeaker system is a
two-way, vented low frequency
enclosure using a 12" low frequency
driver paired with a 90° (horizontal) by
40° (vertical) high frequency
waveguide. The HF section employs a
1.6 exit/100 mm voice coil compression
driver mounted on one of Peavey’s
revolutionary new Quadratic Throat
waveguides. The ILS 1294 has a full
range sensitivity of 96 dB SPL –
(1 Watt/1 meter) and a maximum output
of 130 dB at 1 meter (full range).
The Peavey ILS 1294 is a high
performance loudspeaker system for
use in demanding sound reinforcement
applications. The robust construction of
the ILS 1294 provides power handling
capacities of 750 W continuous, 1.5 kW
program and 3.0 kW peak (full range).
The unit may be operated using the
internal passive crossover or may be
biamplified. Twelve 3/8"x16 threaded
mounting suspension points (2 each
top, bottom and back and 3 each sides)
allow a variety of suspension

configurations. Multiple units may be
mounted to form a vertical/horizontal
array [see limitations under mounting
instructions]. Both versions of the ILS
1294 are solidly constructed of 3/4"
void-free poplar plywood and finished
with an exterior grade hardened black
paint.

determining how accurately a given
unit reproduces an input signal. The
frequency response of the ILS 1294H
is measured at a distance of 1-meter
using a 1 Watt (into the nominal
impedance) swept-sine input signal.
As shown in figure 1, the selected
drivers in the ILS™ 1294H combine to
give a smooth frequency response
from 63 Hz - 18.5 kHz.

Specifications
The loudspeaker system shall

have an operating bandwidth of 63 Hz
- 18.5 kHz. The nominal output level
shall be 96.0 dB when measured at a
distance of one meter with an input of
one Watt. The nominal impedance
shall be 8.0 Ohms. The maximum
continuous power handling shall be
750 Watts, maximum program power
of 1,500 Watts and a peak power
input of at least 3,000 Watts, with a
minimum amplifier headroom of 3 dB.
The nominal radiation geometry shall
be 90 degrees in the horizontal plane
and 40 degrees in the vertical plane.
The outside dimensions shall be
17.50 inches high by 30.75 inches

weight shall be 80 pounds. The
loudspeaker system shall be an

Second and third harmonic
distortions vs. frequency are plotted in
figures 5 and 6 for two power levels,
ten percent (10%) of rated input
power and either one percent (1%) of
rated input power or one watt,
whichever is greater. Distortion is read
from the graph as the difference
between the fundamental signal
(frequency response) and the desired
harmonic. As an example, a distortion
curve that is down 40 dB from the
fundamental is equivalent to 1%
distortion.
Directivity
Beamwidth is derived from the
-6 dB points from the polar plots (see
figure 3) which are measured in a
whole space anechoic environment.
Q and Directivity Index are plotted for
the on-axis measurement position.
These are specifications that provide
a reference to the coverage
characteristics of the unit. These
parameters provide insight for proper
placement and installation in the
chosen environment. The blending of
the components of the ILS 1294H
exhibit a desirable beamwidth and
directivity (figure 3 and 4) suitable for
sound reinforcement applications.
Mounting
Caution: Before attempting to
suspend this speaker, consult a
certified structural engineer. Speaker
can fall from improper suspension,
resulting in serious injury and property
damage. Other enclosures may be
suspended below one ILS 1294H.
However, the combined weight of
additional enclosures and all cables,
clamps and other hardware must not
exceed 320 pounds. The ILS 1294H
weighs 80 pounds and the maximum
combined weight suspended from the
uppermost mounting bracket
