zoidal shape, along with a coated perforated metal grille to offer a cosmetically elegant yet durable system.
The two-way system includes a 15"
Black Widow woofer with a Kevlar
¨
impregnated cone and a specially treated
surround, cone and dust cap for excellent
weather resistance. The 22XT compression driver features a 2" titanium
diaphragm, 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 bi-amplification are made
via a lock-down switch selected mode of
operation for the Neutrik connectors, or
instant access 1/4" switching jacks. 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 62 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 enclosure
reproduces an input signal.
The frequency response of the Impulse
500 is measured at 1 meter using a 2.82volt, swept-sine input. The selected driver
in the Impulse 500 combine to give a
smooth frequency response from 62 Hz to
18 kHz.
DIRECTIVITY:
Beamwidth and directivity factors are
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 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
ª
500 exhibit a desirable
beamwidth and directivity (figures 3 and 4)
suitable for sound reinforcement applications.
POWER HANDLING:
There are many different approaches to
power handling ratings. Peavey rates this
speaker systemÕs power handling using a
modified form of the AES Standard
3
Harmonic Distortion at 1/100 Rated Power
HARMONIC DISTORTION
Second and third harmonic distortion vs. frequency is plotted in two
power levels: one tenth of rated input power and either one one
hundredth of rated input power or 1 Watt, whichever is higher.
Distortion is read from the graph as the difference between the
fundamental signal and the desired harmonic. As an example,
distortion that is 40 dB down from the fundamental signal
is equivalent to 1% distortion.

2-1984. Utilizing audio band 20 Hz to
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 todayÕs 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 allows for exposure of the speaker
to synthesized tones that may extend
beyond audibility. This rating is contingent
on having minimum 3 dB of amplifier
headroom available.
ARCHITECTURAL AND ENGINEERING
SPECIFICATIONS:
The loudspeaker system shall have an
operating bandwidth of 48 Hz to 18 kHz.
The output level shall be 100 dB when
measured at a distance of 1 meter with
an input of 1 watt. The nominal impedance shall be 8 ohms. The continuous
power handling shall be 350 watts, maximum program power of 700 watts, and a
peak power handling of 1,400 watts, with
a minimum amplifier headroom of 3 dB.
The peak SPL with inaudible distortion
shall reach 133 dB with music as a
source, when measured at a distance of
1 meter and driven to rated power. The
system shall utilize a 15" Black Widow
woofer and a 22XT compression driver
tweeter. The nominal radiation pattern
shall be 90 degrees in the horizontal plane
and 45 degrees in the vertical plane. The
cabinet is to consist of injection-molded
polypropylene of 1/4" nominal thickness,
with internal reinforcing ribs. A handgrip
shall be present on each side of the cabinet next to the woofer and a handle on the
top rear edge. A vinyl-coated perforated
metal grille shall be provided for woofer
protection. The cabinet shall incorporate
four tall sturdy rubber feet for floor standing use and four mounting point inserts
top and bottom for flying use. The outside
dimensions shall be 28 9/16" tall by
21 5/16" wide (11 1/2" wide in rear) by
17" deep. The weight shall be 56 lbs. The
input connection shall be made available
via two 1/4" phone jacks and two 4-pin
Neutrik Speakon connectors, all connected in parallel for full range use, and a
locking switch to select bi-amp use for the
Neutrik connectors and instant access
1/4" switching jacks for bi-amp use with
1/4" phone jacks. The loudspeaker system
shall be a Peavey model Impulse 500.
Warning! When use of
a stand is considered,
the Peavey S-1ª stand is recommended. Other stands may
not have a base sufficiently
wide enough for stability and
safety.
CAUTION! For permanent
outdoor installation, avoid
direct cone exposure to sunlight
and rain by tilting speaker down
and use a splash shield on top.
WARNING! Before
attempting to suspend
this speaker, consult a certified
structural engineer. Speaker can
fall from improper suspension,
resulting in serious injury and
property damage. Do not suspend or mount any other product or device from this enclosure! Use only Grade 5 hardware or better.
