Qsc Llc PL-SUB15 15 Inch Passive Subwoofer

Product Description

The QSC LLC PL-SUB15 is a 15-inch passive installation subwoofer designed for fixed low-frequency reinforcement in commercial and professional audio environments. As a passive unit, it requires an external amplifier to drive the speaker, making it a flexible component in larger installed sound systems. The 15-inch driver delivers extended bass reproduction suited to demanding acoustic spaces. Installation is typically handled by a licensed audio systems integrator or AV contractor working within a structured cabling and amplification infrastructure.

The PL-SUB15 is intended for permanent installation applications such as houses of worship, performance venues, conference centers, and large commercial spaces where low-frequency coverage must integrate with an existing distributed audio system. It is sold as a single unit and is designed to work alongside compatible QSC amplification and signal processing equipment within a fully engineered audio system.
