From the Manufacturer

The 108P is the reference live monitor within the L-ACOUSTICS® self powered coaxial P series. The enclosure operates over a frequency bandwidth from 55 Hz to 22 kHz which can be lowered to 40 Hz with the addition of the recommended SB15P self-powered subwoofer. The 108P enclosure contains a bi-amplified coaxial configuration consisting of a 1.5’’ diaphragm compression driver loaded onto an 8’’ low frequency transducer integrated into a compact low profile bass-reflex tuned enclosure. This coaxial transducer arrangement produces a 100° 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 2-channel power amplification module. The DSP manages the system crossover network, driver time alignment, and dual protection of the loudspeaker components. The unique linearization drive characteristic of the transducers is a result of comprehensive parameter management functions by the DSP. Made of high-grade Baltic birch plywood, the cabinet design makes the 108P perfectly suited to all multi-purpose sound reinforcement applications. Its wedge-shape allows monitoring use with a fixed angle setting of 30˚ from vertical. The 108P can also be pole-mounted using the integrated socket or flown using the complementary ETR8-2 bracket
