1.1 OVERVIEW
L-ACOUSTICS 108P and 112P self-powered coaxial loudspeakers are intended for distributed sound
reinforcement in small- to medium-sized portable applications or for use with the SB15P self-
powered subwoofer for 3-way applications such as small- to medium-sized FOH or stage monitoring
(drum/side fill). All P-series enclosures feature highly-advanced loudspeaker components and rigging
accessories while benefiting from the sonic accuracy and flexibility afforded by application-engineered
digital presets.
108P
The 108P is a 250 x 500 watt bi-amplified, digitally-processed loudspeaker featuring a 1" exit HF
compression driver coaxially-loaded by an eight-inch low frequency transducer. Coaxial loading
produces coherent point source radiation with 100-degree axisymmetric directivity along with
superimposed LF/HF dispersion characteristics free of the polar lobing effects associated with
traditional 2-way studio monitor configurations (i.e., separate woofer/tweeter). The end result is
precise, stable image localization that is ideal for stereo or surround sound monitoring.
Integral digital crossover filtering, component time alignment and equalization provide superb sonic
performance plus added flexibility due to the availability of four application-engineered presets (FILL,
FRONT, MONITOR, X-OVER).
Accurate frequency response and imaging combined with elevated SPL output capacity make the
108P ideal for use as a high performance nearfield monitor for live FOH mix engineering and for
stereo or 5.1 monitoring in studio, broadcast or post production environments. For nearfield
monitoring applications, either FILL (free space conditions, for example, when the 108P is placed on
a console bridge) or MONITOR (half space conditions, for example, when the 108P is wall- or soffit-
mounted) presets should be selected.
Due to its’ high power:size ratio, plug-and-play ease-of-use, versatile application-oriented presets and
multi-purpose enclosure format, the 108P is also suitable for a wide variety of portable sound
reinforcement applications. For proximity reinforcement such as distributed front fill, the 108P
provides optimum fidelity and intelligibility, satisfying the strict requirements of classical music and
opera. The compact, truncated wedge-shaped enclosure format provides a visually-discrete solution
for floor monitoring, keyboard monitoring or underbalcony use and with the addition of L-
ACOUSTICS subwoofers, the 108P is also suitable for small format FOH applications.
In addition to proximity fill and monitoring, the 108P can be used for portable distributed sound
reinforcement in theatre, trade show, concert hall, houses of worship, congress centre, club,
restaurant, retail, corporate boardroom or television applications. To facilitate installation, a pole
mount socket is included as standard and an adjustable U-bracket is available as an optional rigging
accessory for ceiling, wall, scaffold or truss mounting.
