Overview

The Monoprice Stage Right 600091 is a self-powered 15-inch subwoofer designed to add authoritative low-frequency reinforcement to live sound systems, DJ rigs, and venue installations. At its core is a 1000-watt Class D amplifier paired with a 15-inch driver, delivering the kind of deep, impactful bass needed to fill rooms and outdoor spaces. The built-in DSP engine handles crossover duties and provides sound-shaping tools that let you optimize the subwoofer's output for different environments without relying on external processing gear.

The enclosure is built from 15mm MDF with a durable sandblasting finish that resists the scuffs and impacts of regular transport and stage use. Connectivity is handled through a combo XLR/TRS input for mic or line-level signals and a matching XLR/TRS output for linking to additional powered speakers, making it easy to build a scalable sound system. Built-in handles and a focus on keeping weight down make the 600091 practical for working musicians and mobile DJs who need to load in and out quickly. Whether anchoring the low end for a band or driving bass for a dance floor, this subwoofer aims to deliver professional-grade performance at Monoprice's characteristically accessible price point.
