The XT range components are compatible with standard L-ACOUSTICS accessories. These accessories include the
loudspeaker cables SP.7, SP10, and SP25 with respective lengths of 0.7m (2.3ft), 10m (32.8ft), and 25m (82ft). Each
cable is 4 conductor cable with 4mm2conductor cross-section (13 SWG, 11 AWG) and features two NEUTRIK®
NL4FC Speakon®connectors.
The XT system is driven and powered exclusively by the L-ACOUSTICS®LA4 amplified controller. This ensures
intelligent protection, filtering, and equalization of the enclosures. 4 channels of amplification are provided along with
the OEM factory preset library, ensuring the optimization and performance of the system within limitations of the
recommended configurations.
Each system design configuration should be first modeled and studied using the L-ACOUSTICS®SOUNDVISION
application software. The software predictions are based on the preset parameters stored in the amplified controllers.
Several amplified controllers can be interconnected and monitored through the proprietary L-ACOUSTICS®L-NET
network using the L-ACOUSTICS®LA NETWORK MANAGER application software.
A detailed description on the use of the LA4 amplified controller, SOUNDVISION and LA NETWORK MANAGER
application softwares are beyond the scope of this manual. Please refer to the appropriate documentation, also available

58XT COAXIAL ENCLOSURE
L-ACOUSTICS®8XT enclosure features a 1.5’’ diaphragm compression driver coaxially-loaded (for HF directivity
control) by an 8’’ low frequency transducer mounted in a bass-reflex tuned enclosure. The internal passive crossover
network uses proprietary third order filters. The linearization and protection of the transducers is defined by the drive
parameters contained in the LA4 amplified controller. The nominal impedance of the 8XT enclosure is 8 ohms.
The coaxial transducer arrangement produces a 100° axi-symmetric directivity output along with a smooth tonal
response free of secondary lobes over the entire frequency range.
Figure 2: 8XT enclosure with rigging components
The wedge-shaped cabinet design makes the 8XT perfectly suited to all multipurpose sound reinforcement
applications. Short or long throw monitoring use can be achieved with two fixed angle settings of either 30° or 40° with
regard to the vertical. The cabinet also features a pole socket to mount the cabinet on a pole stand or to fly the cabinet
using the complimentary L-ACOUSTICS®ETR8-2 accessory. Four inserts are also available for 3rd party
OMNIMOUNT®30.0 SERIES accessories.
The 8XT cabinet is made of high grade Baltic birch plywood, with remarkable mechanical and acoustic properties.

6.1 Rigging material
The integrated rigging components and the wedge-shaped cabinet design of the 8XT enclosure (Figure 2) allow for
various setups such as:
•Wall or ceiling-mounting using L-ACOUSTICS®ETR8-2 mounting accessory.*
•Wall or ceiling-mounting using OMNIMOUNT®30.0 SERIES mounting accessory.*
•Mounting to a 35mm/1.38in pole stand using the integrated pole socket.
•Stacking with two fixed angle settings of 30° and 40° with regard to the vertical.
* A safety eye-bolt accessory can be added using the 8mm/0.31in insert located on the rear face of the 8XT enclosure.
Refer to the “XT and P’’ rigging manual to get acquainted with rigging procedures specific to the
XT range.
6.2 Connecting speakers
The 8XT enclosure is driven and powered by the dedicated amplified controller L-ACOUSTICS®LA4. Each LA4
amplification channel can drive one or two 8XT enclosures in parallel. The channel assignment varies upon the preset
selected by the user for a given application. For more details please refer to the “LA4’’ user manual, also available on
the L-ACOUSTICS internet website @ www.l-acoustics.com.
The 8XT enclosure is equipped with two NL4FC Speakon®connectors wired in parallel: one is for connecting to an
LA4 output channel, and the second is for connecting an additional 8XT enclosure.
To connect the 8XT enclosure to the amplified controller LA4 (Figure 3), L-ACOUSTICS recommends using
L-ACOUSTICS cables SP10 or SP25 with length of 10 m (32.8ft) and 25 m (82ft), respectively. Cable SP.7 should be
used for connection between two adjacent 8XT enclosures.

Figure 3: Connecting two 8XT in parallel to an LA4 amplified controller
To ensure both high performance and safety, L-ACOUSTICS recommends the exclusive use of
high-quality, fully insulated speaker cables made of stranded copper wire.
In order to preserve a high damping factor it is desirable to keep loudspeaker cables as short as
possible and with a gauge offering low resistance per unit length.
The following table provides information regarding the recommended wire cross-section versus length. Two cases are
possible depending on the impedance load value connected to the LA4 (8 ohms for a single 8XT enclosure, 4 ohms for
two 8XT enclosures in parallel):
Table 1: Minimum wire cross-section versus length for Damping Factor > 20

7OPERATION
7.1 8XT system configuration
The choice of a final XT system configuration should be the result of an electro-acoustic study conducted by an expert
(System Engineer or Audio Consultant), which will not be discussed here as sound-design aspects are beyond the scope
of this manual. This study can rely on the simulations modeled in SOUNDVISION, yielding electro-acoustic predictions
taking into account the manufacturer’s 8XT data, its particular situational usage, and its projected environment.
Various configurations in accordance with system recommendations are possible. Each configuration is associated with a
specific operation mode and its related factory preset. Other hazardous or non-conforming configurations do not
correspond to approved operation modes and therefore are not supported by a factory preset.
Note: The latest version of the preset library can be supplied by L-ACOUSTICS authorized representative and is also
downloadable on the L-ACOUSTICS internet website @ www.l-acoustics.com.
The 8XT enclosures can be used either in a standalone configuration in the “FULL RANGE’’ mode, or in combination
with subwoofers in either the “HIGH PASS’’ or “LF EXTENSION’’ modes.
For each mode a distinction is drawn between ‘‘FRONT’’, ‘‘FILL’’, and ‘‘MONITOR’’ presets as they respectively
match front-of-house, distributed applications, and half-space loading operating conditions. The user can either select
presets using the LA4 front panel interface or the LA NETWORK MANAGER software.
LA4 output channel assignment varies upon the preset selected by the user.
Always check that the 8XT is connected to the correct output channel before operating.
7.2 “FULL RANGE” mode
In ‘‘FULL RANGE’’ mode the 8XT enclosures are used in standalone configurations within their nominal bandwidth, for
applications not requiring low frequency extension.
7.2.1 Connecting to the LA4
Each of the 8XT enclosures is connected to an LA4 output channel ranging from channel 1 through 4 for the first four
cabinets. The additional cabinets are grouped in pairs in parallel with the first ones. Therefore a single LA4 amplified
controller can drive up to eight 8XT enclosures (Figure 4).
Driving eight 8XT enclosures with a single LA4 amplified controller solicits system resources to their
limits and can trigger the thermal protection feature of the controller. This configuration has to be
avoided when the power requirements are extreme and continuous over a long period.
Additional enclosures beyond eight 8XT need to be connected to an additional LA4 amplified controller following the
same wiring procedures. Therefore, each group of 8 additional 8XT requires the addition of a new LA4 amplified
controller.
Note: System resources are optimized for a multiple of 4 8XT enclosures.

7.4.1 Connecting to the LA4
The SB118 and 8XT enclosures are connected to an LA4 outputs as follows: channels 1 and 3 are dedicated to one
SB118 each, and channels 2 and 4 are dedicated to one 8XT each. Each 8XT enclosure can be paired in parallel with an
additional 8XT. Therefore, a single LA4 amplified controller can drive up to two SB118 and four 8XT enclosures
(Figure 6).
Connect only one SB118 enclosure on each output channel 1 and 3 of the LA4 controller.
Driving two SB118 and four 8XT enclosures with a single LA4 amplified controller solicits system
resources to their limits and can trigger the thermal protection feature of the controller. This
configuration has to be avoided when the power requirements are extreme and continuous over a
long period.
Additional enclosures beyond two SB118 and four 8XT need to be connected to an additional LA4 amplified controller
following the same wiring procedures. Therefore, each group of 6 additional enclosures requires the addition of a new
LA4 amplified controller.
Note: System resources are optimized for two SB118 and two or four 8XT enclosures.

8CARE AND MAINTENANCE
8.1 Maintenance information
The L-ACOUSTICS®8XT enclosure is a technical product designed for intensive and various indoor and outdoor
sound reinforcement applications. To fulfill such demanding conditions, L-ACOUSTICS has designed 8XT with high
grade and reliable components:
•Weather-proof transducers engineered using materials with high immunity to oxidation.
•Baltic birch plywood-made cabinet.
•High resistance, non biodegradable Airnet front grill fabric.
•Screws and rigging points resistant to oxidation.
However, in order to ensure safety and product performance, it is essential to proceed to a frequent inspection of the
8XT cabinet and its internal components. The check frequency varies upon the conditions of system use and comprises
three steps (see section 8.2).
8.2 Testing procedure
a. Check of transducer and enclosure acoustic behavior. Use a sweep frequency generator with a maximum
voltage of 0.2 volts (-12 dBu, -14 dBV), connected to the active input of the LA4 amplified controller. Apply a
sweep from 65 Hz to 20 kHz: the sound should remain pure and free of any unwanted noise. If not, check the
mechanical assemblies and if necessary contact an L-ACOUSTICS authorized representative to repair damaged
components.
0.2 volts is a maximum value.
This can generate very high sound levels at given frequencies.
Use ear protection for operation.
b. Check of mechanical assembly and rigging parts inspection. Inspect the general aspect of assembly and
check that screws are locked tight. Also check the integrity of rigging elements (no signs of deformation, indents,
or rust). If necessary contact an L-ACOUSTICS authorized representative to repair damaged components.
c. Check of external aspect. Check for absence of cracks on the cabinetry. Remove the dust from the front fabric
with a vacuum device.
If paint is applied, protect mechanical parts and do not apply paint to the front grill fabric.
This could fill the fabric holes and deteriorate the acoustic transparency of the material.
