The L-ACOUSTICS
®
115XT HiQ stage monitor is the high end reference within the L-ACOUSTICS
®
XT
Coaxial Range and operates over the 50 Hz to 20 kHz frequency bandwidth. The system response can be e tended
down to 32 Hz with the addition of the L-ACOUSTICS
®
SB18 subwoofer.
The system approach developed by L-ACOUSTICS
®
for the XT range consists of the elements needed to fully take
advantage of the possible configurations and optimize the system. The main components of the system are (see also
Figure 1and Figure 2):
8XT  Passive compact coa ial enclosure
12XT  Active/passive multipurpose coa ial enclosure
115XT HiQ  Active coa ial stage monitor
ETR8-2  Mounting accessory for the 8XT enclosure
ETR12-2  Mounting accessory for the 12XT enclosure
ETR15  Mounting accessory for the 115XT HiQ enclosure
XTLIFTBAR  Rigging accessory for the 12XT and 115XT HiQ enclosures
SB18  Subwoofer enclosure
LA4 / LA4X  Amplified controller
LA-RAK  Touring rack containing three LA8 amplified controllers
LA NETWORK MANAGER  Remote control software
SOUNDVISION  Acoustical and mechanical modeling software
SB18 / SB18i / SB18m
In this document, the SB18 term and illustration will refer equally to SB18, SB18i or SB18m. These
products are different versions of the same subwoofer and share the same operating modes, presets and
recommended configurations.
The XT range components are 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 ft,
10 m/30 ft, and 25 m/80 ft. These cables allow connection of the 8XT, 12XT and 115XT enclosures to the LA4 /LA4X
amplified controllers. 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 L-ACOUSTICS
®
DOFILL-LA8 cable allows connection of the 115XT HiQ enclosure to the LA8 amplified
controller. This cable features 8-point PA-COM
®
and 4-point Speakon
®
connectors and must be e tended using the
L-ACOUSTICS
®
DO.7, DO10, or DO25 cables with respective lengths of 0.7 m/2 ft, 10 m/30 ft, and 25 m/80 ft.
Each DO cable is an 8-conductor cable with 4 mm
2
conductor cross-section (13 SWG, 11 AWG) and features
8-point PA-COM
®
connectors. Note: The PA-COM
®
standard is fully compatible with the CA-COM
®
standard.
ALWAYS connect the new DOFILL-LA8 cable on the LA8 amplified controller for active 2-way
applications, as using the old DOFILL cable may result in damaging t e loudspeaker components.
The 8XT and 12XT are driven and powered by the L-ACOUSTICS
®
LA4 or LA4X amplified controller and the
115XT HiQ by the LA4X or LA8. These controllers ensure intelligent protection, filtering, and equalization of the
enclosures. Four channels of amplification are provided along with the OEM factory preset libraries, ensuring the
optimization and performance of the systems within the limits of the recommended configurations.
The L-ACOUSTICS
®
LA-RAK touring rack offers an advanced solution for all L-ACOUSTICS
®
systems covering signal
and power distribution in a comprehensive plug and play touring package. The LA-RAK was created as a universal
platform designed to facilitate cross-rental and to ensure compatibility with the L-ACOUSTICS
®
legacy analog cabling
standard.
Each system design configuration should first be modeled and studied using the L-ACOUSTICS
®
SOUNDVISION
software. The software predictions are based on the preset parameters stored in the amplified controllers.

The L-ACOUSTICS
®
115XT HiQ contains a 3’’ diaphragm compression driver loaded by a constant directivity
conical waveguide united in a coa ial configuration with a 15’’ low frequency transducer integrated into a compact low
profile bass-refle tuned enclosure.
Managed by the LA4X or LA8 amplified controllers, the 2-way active filtering encompasses advanced crossover
functions, system EQ, HF and LF transducer time-alignment, and protection of the transducers. The linearization and
protection of the transducers is defined by the drive parameters contained in the LA8 or LA4X amplified controller.
The impedance of the 115XT HiQ is 8 ohms for each of the LF and HF sections.
The coa ial transducer and conical waveguide arrangement produces a 50° a i-symmetric directivity output along with a
smooth tonal response free of secondary lobes over the entire frequency range. This arrangement also provides
immunity to feedback.
The wedge-shaped cabinet design makes the 115XT HiQ perfectly suited to all stacked sound reinforcement
applications (in particular, short or long throw monitoring use). The cabinet can also be flown as well as pole, wall, or
ceiling-mounted.
The 115XT HiQ cabinet is made of high grade Baltic birch plywood with remarkable mechanical and acoustical
properties for improved long term durability.
