Description
The new SP 12M is a two-way
floor monitor speaker system
comprised of a 12" Black Widow
®
spider-frame BWX woofer with a
Kevlar
®
/carbon fiber-impregnated
cone and an enclosure made from
nine-ply Baltic birch. The
thoroughly braced cabinet is
covered with a durable black
carpet and provided with a heavy
duty perforated steel grille with a
dark grey powder coating. An SA1 stand mount adapter is built in
for side-fill or PA use.
The low frequencies are provided
by the 12" Black WidowBWX SF
woofer with a Kevlar
®
/carbon
fiber-impregnated cone and dust
cap. Capable of over 500 Watts of
continuous power handling (AES
Std 2-1984), the woofer can
handle a lot of power, which also
results in very low power
compression. The high
frequencies are handled by a 2"
Rx™22 titanium diaphragm
compression driver utilizing
ferrofluid cooling. This superb
driver is coupled to a constant
directivity horn with smooth,
even response and good high
frequency dispersion. The Rx™22
driver features the Radialinear
Planar Phase Correction System
(U.S. Patent 6,064,745), which
provides smoother and extended
high frequency response.
Input connection to the system is
made via two 1/4" phone jacks
and a four-pin Neutrik®in
parallel. The internal passive
crossover features the Sound
Guard™III tweeter protection
circuit and an advanced topology
crossover with high performance
components to provide high
power handling and reliability.
Sound Guard
™
,Peavey’s
proprietary high-frequency driver
protection circuitry, provides
long- and medium-term driver
overload protection without
impairing musical transients or
dynamics. The crossover
provides driver roll off and
protection as well as driver EQ for
the woofer and horn for clean,
clear, smooth response. High
quality, reliable crossover
components include
polypropylene capacitors and
high current inductors. The
optimal integration of the
crossover with the selected
drivers results in a smooth
frequency response from 108 Hz
to 14 kHz, making it highly
appropriate for monitor
applications.
Despite its compact dimensions,
this system can put out some
very high sound levels and
handle 1000 Watts of undistorted
amplifier power program,
resulting in clean monitoring with
high articulation and reliability.
Frequency Response
This measurement is useful in
determining how accurately a
given unit reproduces an input
signal. The frequency response of
the SP 12M 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 SP 12M combine to
give a smooth frequency
response from 108 Hz to 14 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.
Mounting
This unit is not designed for over
head suspension. Includes builtin SA-1 stand mount adapter.
Eight rubber feet on two sides
enable dual-angle use.
