The
L-ACOUSTICS
®
SB18
is the universal subwoofer designed for modular or fixed angle WST
®
line sources
(KUDO
®
, KIVA/KILO, KARA
®
, ARCS
®
)
and coaxial systems (XT), lowering the combined system operating range down
to 32 Hz. Its compact size and integrated rigging make it extremely well suited for flown coupled configurations with
KARA
®
(refer to the
KARA Rigging manual
[3.4]).
The system approach developed by L-ACOUSTICS
®
for SB18 consists of the elements needed to fully optimize the
possible configurations. The main components of the system are (see also Figure 1 and Figure 2):
SB18
Compact high power subwoofer
M-BUMP
Structure for flying or stacking a vertical KARA and/or SB18 array
M-BAR
Extension bar for M-BUMP
M-JACK
Stacking bases (x4) for vertical KARA and/or SB18 arrays
SB18PLA
Removable front dolly board for SB18
SB18COV
Protective cover for SB18
8XT, 12XT, 115XT HiQ
XT coaxial range enclosures
KIVA, ARCS

KILO
LF extension for KIVA

The SB18 subwoofer is compatible with standard L-ACOUSTICS
®
accessories. These accessories include the
L-ACOUSTICS
®
SP.7, SP10, and SP25 Loudspeaker cables
with respective lengths of 0.7 m/2.3 ft, 10 m/32.8 ft,
and 25 m/82 ft. These cables allow connection of the SB18 enclosure to the LA4 amplified controller. Each cable is a 4-
conductor cable with 4 mm
2
conductor cross-section (13 SWG, 11 AWG) and features 4-point SpeakON
®
connectors.
The combination of the
L-ACOUSTICS
®
DOSUB-LA8 Loudspeaker cable
with the
DO.7, DO10, or DO25 cable
allows connection to the LA8 amplified controller. These are 8-conductor cables with 4 mm
2
conductor cross-section
and feature
8-point PA-COM
®
and/or 4-point SpeakON
®
connectors.
Note:
The PA-COM
®
standard is fully
compatible with the CA-COM
®
standard.
The SB18 can be driven
and powered by both
L-ACOUSTICS
®
LA4 and LA8 Amplified controllers
[3.4]. These
ensure intelligent protection, filtering, and equalization of the enclosures. Four channels of amplification are provided
along with the
factory LA4 or LA8 PRESET LIBRARY
[3.4], ensuring the optimization and performance of the
system within the limits of the recommended configurations.
Each full range system configuration should first be modeled and studied using
L-ACOUSTICS
®
SOUNDVISION
Software
[3.4]. Software predictions are based on the preset parameters stored in the amplified controllers.
Note:
The acoustic data are not available yet for subwoofers.
Up to 253 amplified controllers can be interconnected and monitored through the proprietary
L-ACOUSTICS
®
L-NET
Network
using
LA NETWORK MANAGER Software
[3.4].
