Frequency response
This measurement is useful in determining
how accurately a given unit reproduces an
input signal. The frequency response of the
SSE 12M is measured at a distance of 1
meter using a 1 Watt swept-sine input signal
(into the nominal impedance) . As shown in
figure 1, the selected drivers in the SSE 12M
combine to give a smooth frequency
response from 79 Hz to 17 kHz .
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 available amplifier
headroom.
Harmonic distortion
Second and third harmonic distortions vs.
frequency are plotted in figures 3 & 4 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.
