JBL PRX915XLF

JBL PRX915XLF Powered Subwoofer

The PRX915XLF is a compact yet powerful 15-inch powered subwoofer engineered for recording studios and project spaces that demand serious low-end extension without consuming excessive floor space. Its Class D amplifier delivers authoritative bass response while the fanless cooling design keeps the cabinet silent during operation, making it ideal for tracking sessions, mixing, and accurate studio monitoring applications.

Amplification & Output

Built-in Class D amplifier rated at 1000W RMS / 2000W Peak powers the 15-inch 915SG woofer with a 3-inch voice coil and ferrite magnet. The system achieves 131 dB SPL @ 1m, providing sufficient headroom for critical mixing and mastering work without compression or distortion at typical monitoring levels.

Connectivity & Control

Dual combo inputs accommodate both XLR and 1/4-inch connections, while 2x XLR pass-through outputs allow integration with additional studio monitors or subwoofers in a cascaded monitoring setup. The 6-band parametric EQ, selectable 80Hz / 100Hz / 120Hz crossover frequencies, 20ms delay, and 0–12dB input gain provide comprehensive tuning options for room-specific calibration; Bluetooth Low Energy control via the JBL Pro Connect app enables remote adjustments from the console or listening position without leaving the mix seat.
