-The SR18S 18” 1600 W Professional Powered Subwoofer features the latest acoustic processing technology, powerful amplification, and versatile configurations. 
-Designed for real-world working musicians, DJs, events, venues, and beyond. 
-Its 1600 W Class-D amplifier delivers reliable, consistent performance in a lightweight package, while a custom high-efficiency driver ensures deep, punchy low-end. 
-With built-in processing for system protection, the SR18S monitors amplifier load in real time to prevent overloads, preserving sound quality even under heavy limiting. 
-Custom “Voicing” presets (Flat, Deep, Punch) make it easy to dial in the right bass character depending on music style or venue.
