ELECTRO-ACOUSTICS
X4i is an installation-specific miniature coaxial system designed for short
throw applications requiring seamless integration in the smallest spaces. X4i
features a 1.4” diaphragm compression driver coaxially loaded by a 4”
neodymium low-mid frequency transducer mounted in a closed cabinet.
X4i operates from 120 Hz to 20 kHz and delivers a peak SPL of 116 dB. The
coaxial transducer arrangement produces a 110° axisymmetric directivity with a
smooth tonal response free of secondary lobes over the entire frequency range.
The internal passive crossover network uses custom filters. The L-Acoustics
amplified controllers L-Drive parameters ensure the linearization and
protection of the transducers.
PHYSICAL
The X4i cabinet is made of first grade Baltic birch plywood to ensure
maximum acoustical and mechanical integrity. Its compact and elegant enclosure
weighs only 1 kg / 2.2 lb and is extremely shallow – less than 10 cm / 4 in –
to fit within the depth allowed by conventional construction.
The minimalist dimensions and the flexible accessories make for an easy
integration in any situation, may this be on a wall, on a ceiling, in its
standard version or integrated within these in the recessed version X4r. An
optional white or RAL architectural program allows X4i or X4r to blend into
the architecture of a venue.
The weatherized X4i features two screw terminals that can be protected by a
connector sealing plate with two cable glands, reaching an IP55 rating, making
X4i ideal for outdoor operation.
APPLICATIONS
X4i is an ideal fill enclosure. It delivers exceptional output and broad
bandwidth that perfectly complement larger systems. Supplemented by an
L-Acoustics subwoofer, the weatherized X4i is also ideal as a background music
system in venues that demand discretion and premium audio quality. The coaxial
design combined with the shallow enclosure and the optional RAL color program
integrates seamlessly in architecturally challenging environments to ensure
excellent spatialization and no minimum listening distance. 
RIGGING
X4i can be mounted on a wall and ceiling, mounted on a microphone pole or
stacked via the brackets or wall-mount accessories. Wall-mount accessories
allow for Pan and Tilt orientation. For the highest level of discretion, the
recessed version X4r can be mounted in-wall and in-ceiling, recessed behind a
custom-colored front screen.
AMPLIFIED CONTROLLERS
LA2Xi and LA4X are the recommended amplified controllers with four X4i per output channel. For multi-channel configurations, LA7.16i offers the most efficient amplification solution.

X series: a complete range for professional sound reinforcement
The X Series is comprised of five coaxial enclosures with distinct formats,
bandwidth, SPL and coverage angles adapted to short throw applications in
rental productions and fixed installations. With studio monitor sound quality,
the X Series convey a natural and transparent sound.
Coaxial technology allows for a compact design and constant tonal balance over
distance, giving the X Series smooth coverage for off-axis audiences, no
minimum listening distance and high feedback rejection.

About coaxial technology
In 1989, L-Acoustics introduced the first coaxial loudspeaker enclosure for
professional sound reinforcement, bringing studio quality to near-field
applications for the first time. Since then, coaxial technology has been
implemented in all L-Acoustics point sources.
A coaxial design approach aligns LF and HF acoustic centers to achieve a
single point source radiation with coherent wavefront at all frequencies, that
is free of polar lobing effects, typical of traditional horn and woofer
combinations. This results in natural, studio monitor sound quality, ideal for
proximity use.

X4i SHORT THROW POINT SOURCE
X4i is an installation-specific miniature point source system designed for
short throw applications. Part of the X Series, X4i is a 4“ format loudspeaker
that provides exceptional output and broad bandwidth for its size, ensuring
premium sonic performance in an extremely compact enclosure.
X4i is a two-way passive enclosure with transducers mounted coaxially to
produce a 110° axisymmetric directivity with a smooth tonal response free of
secondary lobes over the entire frequency range. Housed in a cabinet made of
first grade Baltic birch plywood, X4i weighs only 1 kg / 2.2 lb and is
extremely shallow – less than 10 cm / 4 in – to fit within the depth allowed
by conventional construction.
The combination of minimalist dimensions, flexible accessories, white and RAL
architectural programs and an IP55 rating make for an easy integration in any
situation. On its own, X4i is an ideal complement to larger systems in venues
that require seamless integration in the smallest spaces such as theaters,
houses of worship, corporate facilities and studios. Supplemented by a
subwoofer, X4i is also perfect as a distributed background music system,
indoor or outdoor, in bars, restaurant, conference rooms, museums and other
hospitality venues.
