Frequency response
This measurement is useful in determining
how accurately a given unit reproduces an
input signal. The frequency response of
the SSE 12 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 SSE 12 combine to give a smooth
frequency response from 79 Hz to 17 kHz.
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
specifications provide a reference to the
coverage characteristics of the unit and
provide insight into proper placement and
installation in the chosen environment.
The blending of the components of the
SSE 12 exhibit a desirable beamwidth and
directivity (figures 3 & 4) suitable for
sound reinforcement applications.
Power handling
There are many different approaches to
power handling ratings. Peavey rates this
loudspeaker system’s power handling
using a full-range form of the AES
Standard 2-1984. Using audio band 20 Hz
to 20 kHz pink noise with peaks of four
times the RMS level, this strenuous test
signal assures the user that every portion
of this system can withstand today’s high
technology music. This rating is contingent
upon having a minimum of 3 dB of
amplifier headroom available.
Harmonic distortion
Second and third harmonic distortions vs.
frequency are plotted in figures 5 & 6 for
two power levels. Ten percent (10%) of
rated input power and either one percent
(1%) of rated input power or 1 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.
Mounting
Caution: Before attempting to suspend or
mount this speaker, consult a certified
structural engineer. The speaker may fall
due to improper installation, resulting in
serious injury and property damage. DO
NOT suspend or mount any other product
or device from this enclosure. The
maximum enclosure angle is 45°. Use only
Grade 5 hardware or better. All associated
rigging is the responsibility of others.
