Electro-Voice PI115L is a modular, low-frequency sound reinforcement system designed for permanent installations. It features a horn-loaded design with an EVX-150A woofer for powerful and reliable bass output. With a frequency response ranging from 50 to 200 Hz, the PI115L delivers extended low-end performance. Its trapezoidal shape allows for easy configuration of arrays, while the angled enclosure sides enable ceiling mounting with a reduced vertical profile for a more discreet appearance.
