1 XT RANGE

The L-ACOUSTICS

XT series offer a range of four coaxial enclosures with distinct formats, SPL capabilities and

coverage angles. Intended for rental productions and fixed installations, the XT series delivers remarkable acoustic

properties for various short-throw applications, including FOH systems, distributed systems, side-fill monitors, stage

monitors and complementary fills.

The system range and components are as follows:

 5XT, passive ultra-compact enclosure, 110° axi-symmetric, 95 Hz to 20 kHz;

 8XT, passive compact enclosure, 100° axi-symmetric, 65 Hz to 20 kHz;

 12XT, active / passive enclosure,90° axi-symmetric, 55 Hz to 20 kHz;

 115XT HiQ, active floor monitor, 50° axi-symmetric, 50 Hz to 20 kHz;

 LA4 and LA8 amplified controllers.

An XT coaxial enclosure constitutes a real point source and offers total wave front coherence within its beam width:

linear phase response, no lobbing or comb effects, even coverage angle over frequency, no minimum listening distance

and even tonal balance over distance. The XT sound quality is worthy of studio monitor performances and listeners can

experience a natural and transparent aural sensation.

By providing high SPL, wide directivity patterns and even sonic performance off-axis, the XT technology allows an

extensive coverage with few elements and is suited to various sound reinforcement applications as a main or

complementary system.

In semi-reverberant spaces, an XT point source produces far less reflected virtual sources than a classic horn-woofer

combination and therefore offers a much more coherent sound field.

In distributed applications, listeners will benefit from the near field coherency of the enclosure, and an excellent

directivity control allows XT sources to be precisely aligned, avoiding cross-cancelation in the HF/MF region.

This directivity control, along with the absence of lobbing effects, also provides high feedback immunity to monitoring

applications. With a remarkable vocal presence, a clear sound and a smooth radiation pattern, the artist will enjoy

performing with XT monitors.

XT enclosures are easy to integrate. More compact than classic 2-way enclosures, they preserve sightlines. The axi-

symmetrical directivity allows setting them up horizontally or vertically indifferently. Mounting is quick and easy due to a

hardware which ensures precision, safety and full compatibility with rigging standards. The wedge shape of cabinets

allows floor monitoring applications. Any XT configuration can be acoustically and mechanically modeled with L-

ACOUSTICS

SOUNDVISION 3D simulation software.

The LA4 and LA8 amplified controllers and their preset libraries constitute an extremely advanced and precise drive

system for the XT enclosures. All L-ACOUSTICS amplified controllers feature the L-DRIVE, a thermal and over-

excursion protection circuit.

Up to 253 LA8 amplified controllers can be connected together via the Ethernet-based L-NET protocol. The LA

NETWORK MANAGER software allows online remote control and monitoring of all the connected units, via a user-

friendly and intuitive graphic interface.
