Description:
The SP 6G is the result of redesigning the 112SE. They share the
same speaker complement, the 22XT
compression driver/CH-3 constant
directivity horn and the popular 12"
Sheffield woofer. However, changes
have been made to add to the performance and appearance of this unit.
Due to many requests, the SP 6G
features a new trapeziodal cabinet in a
very tight package. This shape greatly
reduces standing waves within the
cabinet and offers the ability to place
several SP 6G’s in an array. Each
cabinet is protected by polymer
corners and Peavey’s durable black
carpet as well as a powder-coated,
expanded metal grille.
This full-range enclosure provides
two parallel 1/4" inputs and both Hi
and Lo inputs for bi-amp use. The SP
6G crossover utilizes Peavey’s
proprietary high-frequency driver
protection circuitry, Sound Guard. The
input signal is routed through the
Sound Guard circuit in both full-range
and bi-amp modes of operation. When
the high-frequency drive level exceeds
a predetermined threshold, the Sound
Guard circuit is engaged

automatically. This subtly decreases
the signal level going to the 22XT so
that it will not be damaged due to longterm overpowering. Short duration
transients will not be attenuated by
Sound Guard and have the possibility
to damage the 22XT. The Sound
Guard circuit is a dynamic circuit that
increases attenuation of the signal as it
increases in amplitude. This is accomplished throught the use of a specially
selected, dynamically resistive light
bulb. If the bulb in your Sound Guard
should ever burn out, a replacement
may be obtained from an Authorized
Peavey Service Center. However, if a
Peavey replacement bulb is not readily
available, an automotive type1156 bulb
may be substituted for temporary use
until a Peavey bulb can be obtained.
Frequency Response:
This measurement is useful in
determining how accurately a given
unit reproduces an input signal. The
frequency response of the SP 6G is
measured at a distance of 1 meter
using a 2.8 volt swept-sine input
signal. As shown in Figure 1, the
selected drivers in the SP 6G combine
to give a smooth frequency response
from 70 Hz to 15.0 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.
These are specifications which provide
a reference to the coverage characteristics of the unit. These parameters
provide insight for proper placement
and beamwidth and directivity (Figure
3 and 4) suitable for sound reinforcement applications.
Power Handling:
There are many different
approaches to power handling ratings.
Peavey Electronics rates this unit's
system power handling using a modified form of the AES Standard 2-1984,
utilizing audio band limited (20 Hz - 20
kHz) pink noise with peaks over 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. The
test signal contains large amounts of
very low- frequency energy, effectively
simulating the frequency content of live
music situations. The full measure of
high frequencies in the test signal
allow for exposure of the speaker
system to synthesized tones that may
extend beyond audibility. This rating is
contingent on having a minimum of
3 dB of amplifier headroom available
so as to ensure that clipping does not
occur.
