LSR310S 10" Powered Studio Subwoofer with XLF

Extend your monitoring system’s low end with confidence. The JBL LSR310S pairs a custom 10" down-firing, high-excursion driver with a 200-watt amplifier and JBL’s patented Slip Stream™ port to deliver deep, dynamic bass that stays tight at any level. Engage the XLF (Extended Low Frequency) setting to emulate the enhanced low-frequency contour of modern club systems—ideal for producing EDM, hip-hop, pop and cinematic tracks that translate to the dance floor. Professional I/O and routing make integration simple: balanced XLR and 1/4" inputs connect to any interface or monitor controller, with XLR outputs for your mains or the “.1” LFE channel in surround workflows. A selectable input sensitivity switch (-10 dBV / +4 dBu) prevents overload, while three crossover options—including an 80 Hz point and an External mode—let you tailor handoff to your studio monitors. With peak output up to 113 dB and response extending into the 20 Hz region, LSR310S reveals sub-bass nuances, kick drum weight and synth fundamentals that smaller speakers miss, helping you make faster decisions and more reliable mixes in any room.
