115XT HiQ - Active Stage Monitor

The XT coaxial range delivers a complete sound reinforcement solution to fulfill the highest demands of audio professionals for both the fixed installation and rental production markets. The XT series delivers the ultimate sonic performance in a compact and multi-purpose package.

Setting up XT enclosures is quick and easy due to the unique integrated flying hardware system which ensures precision, safety and full compatibility with current rigging safety standards. Its compact and wedge-shaped format makes the XT range equally suited to sound reinforcement applications such as front of house, floor monitor and distributed systems.

The XT range has been designed for use with the LA4 amplified controller (LA8 for 115XT HiQ). On board the LA4/LA8 a wide variety of presets are available across the entire XT range, providing the sound designer with total creative freedom for any conceivable application in theatres, clubs, concert halls, broadcast and multipurpose facilities.

L-ACOUSTICS^® introduced the MTD115, the first coaxial loudspeaker for sound reinforcement, in 1989. Initially designed for multipurpose applications, the coaxial technology has demonstrated numerous advantages over classic two-way systems which typically suffer from interference around the crossover point resulting in lobing and uneven frequency and power response.

By superimposing HF and LF acoustic centers in a coaxial design, a virtual point source brings significantly improved radiation characteristics. This is particularly valuable in distributed sound reinforcement applications where most listeners are located off the system axis. As the sound field of coaxial enclosures is stable over the entire frequency spectrum and in all directions, all listeners benefit from an even sonic performance within the enclosure beamwidth.

The particular benefits of coaxial technology are related to the radiation characteristics of a point source. The natural studio monitor sound quality and the aural sensation of transparent sound typical of coaxial systems is adapted to proximity applications such as stage monitoring, front-fills, under-balcony fills and FOH live monitoring.

The point source technology is also suited to distributed applications in semi-reverberant spaces where a single reflected source offers a more coherent radiation field with less reflected virtual sources than a dual acoustic source typical of horn-woofer combinations.

All coaxial systems are available as plug and play solutions with built-in amplification and DSP (P series) or amplified controllers available with a complete set of dedicated preset libraries for FOH, fill and monitor modes. This integrated package offers the user a fast and easy set-up and
ensures performance consistency, predictability and the best possible component protection.
