Dual Load Reex Subwoofer
Architects’ & Engineers’ Specications
The subwoofer loudspeaker system shall be self-
contained and consist of the following components:
(1) a low frequency driver; (2) a two-way crossover
network; (4) a vented enclosure.
The low frequency transducer shall be a cone type
loudspeaker having a diameter of at least 12 inches
(300mm).The cone shall be tted with a high compli-
ance foam surround and treated to resist moisture.
It shall have a voice coil that is at least 3 inches in
diameter and present a nominal impedance load of
8Ω to the crossover networks.
The system shall be crossed over by an internal,
high-level, passive network having a response of
12dB/octave. The nominal crossover frequency shall
be 120Hz. The crossover network shall present, at the
connectors, a high-pass output at 120Hz for the pur-
pose of connecting a full range satellite loudspeaker.
The enclosure shall be a vented design. It shall
be constructed using high density particle board and
nished with black, scratch resistant PVC. It shall be
rectangular in shape. The overall dimensions of the
enclosure shall not exceed (HxWxD) 31.52" x 11.74"
x 20.01" (800mm x 298mm x 508mm). The total
weight of the loudspeaker shall be less than 79.3 lbs.
(35.9kg). Connections to the loudspeaker, input and
output, shall be two dual banana jacks.
The loudspeaker system shall have an overall fre-
quency response of at least 35Hz–200Hz when
measured to –10dB and at least 55Hz–150Hz when
measured to –3dB. Calculated 1W/1m sensitivity
shall be at least 92dB when measured in the far eld
between 50Hz and 150Hz. Maximum SPL shall be at
least 123dB at 1m. The loudspeaker shall be rated
for continuous operation at 300W IEC with 1200W
peaks.
The subwoofer loudspeaker system shall be a
model MSW8 manufactured by Mackie Industrial.
