DESCRIPTION
The Impulse 500 Subwoofer is designed
to be an add-on subwoofer for the
Impulse 500 or the Impulse 200 full range
speaker system. Simply run the normal
full range signal to the Impulse 500, then
run either a 1/4" phone jack terminated
cable, or a four pin Neutrik terminated
cable out from the second jack on the
Impulse 500 full range speaker system
over to the Impulse 500 Subwoofer, and
jack into the ÒFILTERED INPUTÓ on the
subwoofer. The ease and flexibility of
adding on a subwoofer has never been
easier! The system with both the Impulse
500 full range system and Impulse 500
Subwoofer is now a 2.7 ohm composite
system, with a power handling of 450
watts (34.6 V RMS). Bass response has
been extended to approx. 42 Hz, and the
tonal balance of the composite system
has been warmed up to the point where
no bass boost is required.
For biamplification use with an electronic
crossover, just use the unfiltered 1/4"
phone input jack. This input is also useful
for utilizing the Impulse 500 Subwoofer
as a compact, high-output drum monitor.
The Impulse 500 Subwoofer is equipped
with a Peavey innovation called the
HyperVent. This unique vent reduces the
pipe organ resonance of the vent tube
and allows a vent to seem longer in one
dimension than it physically is. Because
the open end of the vent terminated
acoustically, standing waves are reduced
and the hollow sound of an ordinary vent
is avoided. Without these typical vent
ÒsoundsÓ to call attention, the subwoofer
is harder to localize and placement is
less critical.
The Peavey Impulse 500 Subwoofer has
a 15" model 1554 MR Black Widow
woofer in it, providing high-power, low
bass response in a compact system
package.
ARCHITECTURAL AND
ENGINEERING SPECIFICATIONS
The loudspeaker system shall have a
frequency response from 44 Hz to
150 Hz through the filtered inputs, and
from 44 Hz to 2.8 kHz through the unfiltered input. The nominal impedance shall
be 4 ohms. The continuous power handling through the filtered input shall be
300 watts, maximum program power of
600 watts and a peak power handling of
1,200 watts, with a minimum amplifier
headroom of 3 dB. The peak SPL with
inaudible distortion shall reach 119 dB
through the filtered input, and 122 dB
through the unfiltered input with music as
a source, when measured at a distance
of 1m and driven to full output capacity.
The system shall utilize a 15" Black
Widow 1554 MR woofer.
The enclosure shall be constructed of
injection-molded polypropylene of 1/4"
nominal thickness and with a UL flame
rating, and reinforcing ribs internally. A
handgrip shall be molded in on each side
of the woofer and 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 on the top and
bottom each for flying use.
The enclosure shall incorporate a vent of
the type known as a HyperVent.
The outside dimensions shall be 28.562"
(72.55 cm) tall by 21.312" (54.13 cm)
wide (11.5" {29.21 cm} wide in rear) by
17" (43.18 cm) deep and the weight shall
be 52 lbs. The loudspeaker system shall
be called a Peavey Model Impulse 500
Subwoofer.

Warning! When use of a stand
is considered, the Peavey
S-1
ª
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.
