1000-Watt
Subwoofer
®
General
The loudspeaker shall be self-powered and shall
employ one 18-inch diameter, ferrite LF cone
transducer with 4-inch voice coil diameter.
Transducer protection shall consist of a 4-chan-
nel multi-threat limiter.
Internal Amplification
The loudspeaker shall incorporate two Class D
power amplifiers in bridged mode, with a burst
capability of 1,000W total. Distortion (THD, IM,
TIM) shall not exceed <0.05% (20 Hz - 20 kHz).
Dynamic range shall be 119 dB (A-weighted).
Bandwidth shall be 20 Hz - 20 kHz. Amplifier
protection shall be over-current, DC, over/under
voltage, over-temperature, and high frequency.
Performance Specifications
Performance for a typical production unit shall
be as follows, measured at 1/3-octave resolu-
tion: operating frequency range 32 Hz to 110 Hz
@ -6 dB; maximum peak SPL 135 dB.
Rear Panel
Input connectors shall consist of two combina-
tion XLR F / ¼" line inputs. Line input imped-
ance shall be 10 kΩ. Maximum input shall be
+22 dBu. Two XLR M output connectors shall be
provided for throughput. Controls shall consist
of Speaker Level (Variable: -12 dB to +12 dB)
control and Mono Sum Input switch. Indica-
tors shall consist of DSP Preset, Delay Preset,
Polarity Invert, Network Connected, Network
Activity, Wi-Fi Setup, Wi-Fi On, Signal, Limit,
Clip, Thermal.
A USB socket shall be provided for Wi-Fi com-
munication and internal software recovery.
A CAT 5 Ethercon connection shall also be
provided.
Digital Signal Processing
The speaker processing shall have 24-bit depth
and 96 kHz sample rate. The speaker shall have
Normal or Extended Frequency Contour, Normal
or Reverse Polarity options, three onboard delay
settings, and Custom Preset for use with SL
Room Control.
Software
The speaker shall have the option to be con-
trolled by SL Room Control for Windows 7 and
8 (32- and 64-bit support), Mac OS X 10.7 Lion
and 10.8 Mountain Lion, and iPad iOS 7 or later.
SL Room Control shall provide remote control
over onboard DSP contours and polarity; net-
work scanning to detect all speakers; network
browser; performance monitoring of excursion
limiting, real-time temperature, ADC clip detec-
tion, and soft limiting; multiple speaker-group
management with relative level control, 31-band
graphic EQ with preset browser, and speaker
mapping; alignment delay (up to 500 ms),
limiter with variable threshold, DSP input level,
solo, mute, custom labels, and preset browser
for each speaker; and onboard User layer to
store speaker settings, with or without SL Room
Control connected.
Dante Networking Option
An optional card shall be available that houses
one Ethercon connection for Dante™ audio net-
working and remote control via SL Room Control
software. The option card shall provide two
Dante transmitting and two receiving channels
and shall operate at 48 kHz.
Power Requirements

shall 100 to 230V~ 50-60 Hz. Current draw for
the loudspeaker at 1/8 power shall be 150W.
Physical
Loudspeaker components shall be housed in
an enclosure comprised of 15 mm birch with
a black Chemline™ coating. Grille shall be
perforated metal with black, weather-resistant
powder coating. Weight-balanced polymer
handles shall be installed on each side of the
enclosure.
