Description  
The new Peavey ILS1294H  
(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 ILS1294H combine to  
give a smooth frequency response  
from 63 Hz - 18.5 kHz.  
Architectural and Engineering  
Specifications  
The loudspeaker system shall  
Harmonic Distortion  
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  
wide by 17.50 inches deep. The  
weight shall be 80 pounds. The  
loudspeaker system shall be an  
Architectural Acoustics model ILS  
1294H.  
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
