JBL SRX915SF 2,500-watt 15-inch Powered Flyable Subwoofer
Unmatched Low-frequency Performance Designed to complement JBL’s full-range SRX900 loudspeakers, the SRX915SF is a high-performance powered subwoofer in a truck-pack-friendly format. This active sub houses a 15-inch low-frequency driver and a 2,500-watt Class D amplifier, delivering linear low end down to 36Hz and a mighty 130dB maximum SPL. Additionally, its large low-frequency port design enhances airflow and minimizes audible turbulence — even at high output levels. The SRX915SF offers user-controllable DSP, including limiting, filters, delay, and more. It also includes presets for cardioid configurations and optimal use alongside SRX900 loudspeakers.
