L-Acoustics 112P is the versatile model within the L-ACOUSTICS self powered coaxial P series. The enclosure operates over a frequency bandwidth from 50 Hz to 20 kHz which can be lowered to 40 Hz with the addition of the recommended SB15P self-powered subwoofer.
Self-Powered Coaxial Enclosure
The 112P enclosure contains a passive coaxial configuration consisting of a 3’’ diaphragm compression driver loaded onto a 12’’ low frequency transducer integrated into a compact low profile bass-reflex tuned enclosure. This coaxial transducer arrangement produces a 90° axi-symmetric directivity output along with a smooth tonal response free of secondary lobes over the entire frequency range, resulting in exceptional immunity to feedback especially in monitoring situations.
The system contains a speaker management DSP and a single channel power amplification module. The DSP manages the system crossover network, driver time alignment, and dual protection of the loudspeaker components.

Made of high-grade Baltic birch plywood, the cabinet design makes the 112P perfectly suited to all multi-purpose sound reinforcement applications. Its wedge-shape allows monitoring use with a fixed angle settings of 30 ̊ from vertical. The 112P can also be pole-mounted using the integrated socket or flown using the complementary ETR12-2 bracket or XTLIFTBAR accessory.
The enclosure is DSP-optimized for 4 different presets:
• The [FRONT] preset for main FOH system applications
• The [FILL] preset for distributed or complementary system applications
• The [MONITOR] preset for stage monitor applications
• The [XOVER] preset for use with the SB15P compact subwoofer.
The performance of the enclosure depends upon the choice of preset and physical configuration of the system.
