QSC LS118 18-inch Direct-Radiating Active Subwoofer

The QSC LS118 is a high-performance, next-generation active subwoofer designed for professional sound reinforcement in live venues, fixed installations, touring systems, and event production. It features an 18-inch long-excursion, direct-radiating low-frequency driver paired with a powerful integrated Class-D amplifier, delivering high-output, low-distortion bass with excellent clarity and impact.

Key Features
