The EVC-1181S subwoofer comprises a single 18" lowfrequency transducer in an optimally vented enclosure.
It was created to complement the 8-, 12-, and 15-inch
full range EVC systems, including the EVC-1122/VI
Variable Intensity loudspeaker. Like other EVC models,
the EVC-1181S subwoofer was designed and voiced to
work in systems that use other EV-Innovation
loudspeakers (EVU, EVF, EVH, EVA). The EVC-1181S
does not have an internal passive crossover, it requires
a suitable active low pass filter and 4th-order
Butterworth system high pass filter for proper
operation.
The EVC series is an extremely cost effective solution
for many fixed-install applications. The enclosures are
constructed of 15-mm plywood and finished with
EVCoat for enhanced durability. The EV-1181S
subwoofer was designed for floor mounting or
suspension from its multiple M10 rigging points. All
EVC series loudspeakers accept wire gauges up to 10
AWG. The input panel also accepts optional covers
with NL4-type connectors or weatherized gland-nuts.
For 70V/100V operation, the input panel has an
internal landing pad for mounting EV's high-quality
TK-150 audio transformer. Adding a TK-150 to the
EVC-1181S input panel engages EV's patented
Automatic Saturation Compensation (ASC), which
preserves low frequency performance while presenting
a stable load to the amplifier regardless of how many
loudspeakers are connected in parallel. This results in
the ability to drive multiple EVC-1181S subwoofers
from a single dedicated 70V/100V drive channel.

Frequency response and impedance:
Dimensions:
connectors or be adapted for weather-proof single or

adapter plate.
The input panel should include a landing pad and
appropriate electrical connections on the inside of the
loudspeaker cabinet so that the installer can mount
and connect a high-quality audio transformer in series
with the direct low-impedance connection to the
loudspeaker dividing network. When the transformer is
installed, the input circuit network shall be augmented
with a high-pass filter with a current-dependent corner
frequency in order to preserve the full bass response
of the loudspeaker while protecting system amplifiers
from the drop in load impedance that commonly
occurs when audio transformers are driven into
saturation.
The system shall have a single 18-inch, low-frequency
transducer with a nominal impedance of 8 ohms. This
18-inch transducer shall have a 2.5-inch voice coil and
a continuous average power-handling capacity of 400
watts for 8 hours (per AES 2-1984 and ANSI/EIA
RS-426 A). The loudspeaker enclosure shall be
constructed of 15-mm plywood and shall be
rectangular in shape. The grille shall be constructed
from 18 GA powder-coated cold-rolled steel backed
with acoustically transparent fabric [PI: 18 GA
stainless steel backed with acoustically transparent
hydrophobic cloth]. The system shall be capable of
high-level operation with a bandwidth of 38 Hz to 95
Hz (-3 dB down point). The system dimensions shall
be 554.0 mm (21.81 in) wide by 502.5 mm (19.78 in)
high by 718.1 mm (28.27 in) deep. The cabinet shall
employ facilities for suspension from four M10
mounting points. Net weight shall be 32.6 kg (71.9 lb).
The loudspeaker shall be the EVC-1181-B, EVC-1181W, EVC-1181-PIB, or EVC-1181-PIW models from
Electro-Voice.
Architectural and engineering specifications:
The loudspeaker system shall be a one-way passive
system with Euro block input connectors that accept
wire sizes up to AWG 10. The two Euro block
connectors on the input panel should be configured
for a speaker-level, two-conductor input that is
connected in parallel to terminals on a second Euro
block connector so that additional loudspeakers can
be connected in parallel. The remaining pair of
terminals on each of the two connectors should be
configured for a pass-through audio connection. The
input panel should also be able to accept NL4-type
