L-Acoustics US Touts 115xt Hiq at NSCA
L-Acoustics claim their new 115XT HiQ loudspeaker enclosure is a superb tool for the monitor engineer, especially for high SPL applications. Combining the advantages of coaxial technology with the pattern control of conical waveguide loading, the 115XT HiQ is also highly suitable for use in distributed sound reinforcement applications due to its flexible format and advanced rigging accessories.
The coaxial approach to floor monitor design was pioneered by L-Acoustics with the MTD line and provides exceptional coherence in the near field. Advantages of coaxial technology include single point source radiation and total wavefront coherency at all frequencies. The coaxial design also provides LF/HF superimposed dispersion characteristics that are free of polar lobing effects typical of traditional horn and woofer combinations. The end result is natural, studio monitor-level sound quality that is ideal for proximity use in floor monitoring applications.
The 115XT HiQ combines extremely high SPL output capability with brilliant clarity, fidelity and pattern control. The optimum combination of the weatherproof 15-inch loudspeaker (bass reflex-loaded, three-inch voice coil) and the 1.4-inch neodymium compression driver in a coaxial assembly results in exceptional power response stability with high immunity to feedback. Conical waveguide loading focuses mid/high frequency energy over a 45-degree axi-symmetrical pattern while at the same time loading the 15-inch loudspeaker for improved upper-mid-bass efficiency.
The ultra-compact format and low profile of the 115XT HiQ allows for optimum sightlines in even the most confined locations. With the flexibility of dual-angle configurations, the 115XT HiQ can be used for either short- or long-throw monitoring. When used with the L-Acoustics SB118 (or other subwoofers), the 115XT HiQ provides a high performance side-fill or drum monitoring solution.
The 115XT HiQ is also ideal for distributed sound reinforcement and can be used in medium power front-of-house (FOH) applications for theatres, clubs, multi-purpose venues or corporate events. Pole mount sockets are included as standard and optional rigging accessories include an adjustable U-bracket and a vertical coupling adapter.
OEM factory presets are available for approved digital processors (BSS FDS-366 and Soundweb, XTA DP224 and DP226, and Lake Contour), providing flexible solutions for a wide variety of two- and three-way operating modes.
Long-term power ratings at 8 ohms are 375W RMS (1500W peak) on the low-frequency driver and 75W RMS (300W peak) on the high-frequency driver. Frequency response is 65 Hz to 18 kHz (± 3 dB) with a maximum continuous SPL of 132 dB (138 dB peak).
