L-ACOUSTICS®introduced 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.

 

The 115XT HiQ is the high-end model within the L-ACOUSTICS® XT coaxial series, designed for stage monitor and distributed FOH applications. It operates as an active 2-way enclosure, over a frequency bandwidth from 50 Hz to 20 kHz which can be lowered to 32 Hz with the addition of the SB18 subwoofer. The 115XT HiQ enclosure contains a 3’’ diaphragm compression driver loaded onto a constant directivity conical waveguide united in a coaxial configuration with a 15’’ low frequency transducer. Integrated into a compact low profile bass-reflex tuned enclosure this coaxial transducer arrangement produces a 50° axi-symmetric directivity output along with a smooth tonal response free of anysecondary lobes over the entire frequency range, resulting in exceptional immunity to feedback especially in monitoring situations. Made of high-grade Baltic birch plywood, the wedge-shaped cabinet design makes the 115XT HiQ perfectly suited to short or long throw monitoring use with two fixed angle settings of 30? and 60° from vertical. The 115XT HiQ can also be pole-mounted using the integrated socket or flown using the complementary ETR15 bracket or XTLIFTBAR accessory. The control and amplification of the 115XT HiQ is managed by the L-ACOUSTICS® LA8 platform. The active DSP filtering encompasses advanced crossover functions, system EQ, HF and LF transducer time alignment, and dual protection of the transducers (PEAK and RMS). The L-ACOUSTICS® LA8 amplified controller offers the following drive modes: ‘‘FULL RANGE’’ mode for 115XT HiQ standalone use at nominal bandwidth ([HIQ_FR], [HIQ_FI] and [HIQ_MO] presets) ‘‘HIGH-PASS’’ mode with 100 Hz high-pass filter to possibly associate the complementary SB18 subwoofer ([HIQ_FR_100], [HIQ_FI_100] and [HIQ_MO_100] presets) 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 performances of the 115XT HiQ enclosure depend upon the choice of preset and physical system configuration.
