he Bose L1 PRO16 Portable Line Array is a 1250W powered column PA speaker that’s versatile and simple to use. It functions as a main PA in a wide variety of positions, with a pair able to cover an audience up to 250. The onboard DSP processing, 3-input mixer, and easy-to-use tone presets help working presenters, musicians, instructors, performers, and A/V providers get powerful, clean, and clear sound quickly. The J-shaped line array provides 180° horizontal and +0/-30 vertical coverage for a wide and even response throughout the room. An array extension raises the height of the mid-high drivers to an appropriate height for ground deployment. The array can be attached without the extension for use on a stage. The system offers 118 dB of continuous SPL—plenty of volume for small- to mid-sized venues including clubs, houses of worship, conference centers, performance spaces, and meeting rooms. A highly efficient 250W Class-D amplifier powers the sixteen 2" mid-high drivers, while a 1000W Class-D amplifier powers the 10x18" racetrack woofer, providing crisp, detailed sound with a wide frequency range from 20 kHz down to 42 Hz.
