JBL SRX728 Double Bass Passive Speaker Dual 18-Inch Professional Subwoofer

The JBL SRX728 Double Bass Passive Speaker is a flagship professional subwoofer from the renowned SRX700 Series, engineered to deliver powerful, deep, and controlled low-frequency performance for demanding live sound applications. Designed for concert touring, professional DJs, churches, theatres, and event production companies, it provides the high-output bass required for large-scale sound reinforcement.

At the heart of the JBL SRX728 Double Bass Passive Speaker are two high-performance 18-inch long-excursion woofers working together to generate exceptional sub-bass output with impressive efficiency and impact. The dual-driver design significantly increases sound pressure levels compared to single 18-inch subwoofers, making it ideal for venues and events that require substantial low-frequency energy.

The SRX728 delivers tight, controlled bass reproduction while maintaining clarity and musical accuracy. Whether reinforcing live bands, electronic music performances, worship events, or outdoor concerts, it provides the deep low-end foundation needed for a professional audio experience.
