L ACOUSTICS - 115XT HiQ - Active stage monitor (Used)

• High power and sonic performance, clarity and precision
• Exceptional rider friendliness
• Tight coverage pattern and exceptional immunity to feedback
• Dual wedge shape for short or long-throw floor monitoring
• Low cabinet profile for discrete TV stage presence
• Sturdy design and construction for extended longevity
• LA8 advanced system drive and 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.
