JBL LSR310S 10″ Powered Studio Subwoofer

JBL LSR310S 10″” Powered Studio Subwoofer with XLF

The JBL LSR310S is a powered studio subwoofer designed to extend low-frequency performance in professional monitoring systems. Engineered to complement studio monitors, it adds tight, controlled bass response while maintaining accuracy and clarity across the entire system. With a custom 10-inch high-excursion, down-firing driver and a 200-watt Class-D amplifier, the LSR310S delivers deep low-frequency output with impressive headroom and minimal distortion.

A key feature of the LSR310S is JBL’s patented Slip Stream™ Port design. The precisely engineered double-flared port works seamlessly with the driver to optimize airflow, reduce turbulence, and enhance low-frequency extension. This results in smooth, dynamic bass response at any playback level.

The unique XLF (Extended Low Frequency) setting introduces a specially tuned bass contour inspired by modern dance club systems. This mode allows producers to experience enhanced low-end energy, making it ideal for electronic music production and bass-focused content.

Flexible integration is ensured through professional balanced XLR and 1/4-inch TRS inputs and XLR outputs, allowing the subwoofer to function as a low-frequency extension for stereo systems or as the dedicated “”.1″” LFE channel in surround setups. Adjustable input sensitivity and selectable crossover settings provide compatibility with a wide range of studio configurations. Housed in a durable 18 mm MDF enclosure, the LSR310S is built for reliable, long-term performance.
