The 115XT HiQ is a high end enclosure from the L-ACOUSTICS
®
XT coaxial series.
The 115XT HiQ loudspeaker enclosure is based on a 2-way active design with a nominal impedance of 8 ohms for both
the HF and the LF section. It contains a 3’’ diaphragm compression driver loaded by a constant directivity waveguide
and coaxially mounted with a 15’’ low frequency transducer in a bass-reflex tuned enclosure. The cabinet is made of
first grade Baltic birch plywood to ensure maximum acoustical and mechanical integrity. The enclosure can be pole-
mounted by using the integrated socket, or flown by using the ETR15-2 bracket or the XTLIFTBAR bar.
The 115XT HiQ operates over a frequency range of 50 Hz to 20 kHz. This response can be extended down to 32 Hz
with the SB18 subwoofer. The coaxial transducer arrangement produces a 50° axi-symmetric directivity output along
with a smooth tonal response free of secondary lobes over the entire frequency range, resulting in exceptional feedback
immunity.
Its design makes the 115XT HiQ enclosure perfectly suited to various sound reinforcement applications, such as front
of house, distributed applications and half-space loading operating conditions. When the enclosure is laid down on one
of its side, its wedge-shape allows using it as a floor monitor with a site angle of either 30˚ or 60°.
The 115XT HiQ is driven and amplified by the LA4X or the LA8 controller. These ensure linearization, protection, and
optimization for the loudspeaker system.
