compact, weather-resistant package. The
enclosure utilizes high-impact polypropylene in an injection-molded plastic trapezoidal shape, along with a coated perforated metal grille to offer a cosmetically elegant yet durable system.
The two-way system includes a 12"
Black Widow
®
woofer with a Kevlar
®
impregnated cone and a specially treated
surround, cone and dust cap for excellent
weather resistance. The RX™22 compression driver features a 2" titanium
diaphragm, a patented phase plug
(U.S. Patent 6,064,745), and is coupled
to an extremely smooth and well controlled constant directivity horn, with a
coverage pattern of 90 degrees by 45
degrees that is molded into the enclosure.
Input connection to the system is made
via 1/4" phone jacks (2) or 4-pin Neutrik
®
Speakon®connectors. Provisions for
biamplification are made through a 4-pin
Neutrik
®
switching jack. The internal passive crossover features Sound Guard™to
protect the tweeter, and utilizes high performance components and an advanced
topology crossover to provide high power
handling and a smooth yet clear response.
The optimal integration of the crossover
with the selected drivers results in a
smooth frequency response from 75 Hz to
18 kHz.
The free-flow vented cabinet offers
mounting point inserts top and bottom as
well as a molded-in stand adapter for
maximum utility and ease of use.
FREQUENCY RESPONSE:
This measurement is useful in determining how accurately a given unit reproduces an input signal. The frequency
response of the Impulse 1012 (8 ohm) 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
Impulse 1012 (8 ohm) combine to give a
smooth frequency response from 75 Hz 18 kHz.
DIRECTIVITY:
Beamwidth is derived from the -6 dB
points from the polar plots (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 Impulse 1012 (8 ohm) exhibit a desirable beamwidth and directivity (Figure 3
and 4) suitable for sound reinforcement
applications.

Harmonic Distortion : 10% Rated Power
Harmonic Distortion
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.

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 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 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.
