JBL SRX915SF 15-inch Subwoofer
The SRX915SF is a powered subwoofer engineered for recording studios and production environments where low-end authority and precision control are essential. Its compact footprint and efficient design make it practical for home and professional studios while delivering the punch and articulation expected from JBL's touring-grade lineup. The integrated Class D amplifier and extensive DSP toolset allow real-time optimization across different room acoustics and monitoring configurations.
Amplification & Power Handling
A built-in 2,500-watt Class D amplifier with 1100 watts continuous power rating drives the JBL 2276H 15-inch woofer with precision and efficiency. The dual 3-inch voice coil design and Differential Drive technology ensure tight, controlled response for accurate tracking and mix monitoring without thermal stress.
Frequency Response & Studio Performance
The SRX915SF delivers a linear low end down to 36Hz with 130dB maximum SPL, operating across a 43–80 Hz frequency response optimized for subwoofer duty in full-range monitoring systems. Advanced DSP features—including LevelMax limiting, 24 user-adjustable filters, 2,000ms delay, Array Size Compensation, and FIR-based Throw Distance Correction—enable precise tuning to room acoustics and speaker placement for mix-accurate bass translation.
