JBL LSR310S 10" Powered Studio Subwoofer

The LSR310S delivers authoritative low-frequency control in a compact footprint, anchoring professional studio monitoring systems with its custom-engineered driver and intelligent port design. This powered subwoofer integrates seamlessly into existing monitor setups or serves as a dedicated ".1" channel in surround configurations, offering precise bass extension down to 27 Hz with 113 dB peak output capability.

Audio Performance & Low-Frequency Extension

The 250mm high-excursion down-firing driver paired with JBL's patented Slip Stream™ Port produces deep, dynamic bass response across all playback levels, reaching into the 20 Hz region. Three crossover settings—80 Hz, XLF, and External—provide flexibility for different monitoring scenarios, including a club-inspired XLF tuning mode that emulates the bass characteristics of professional dance venues.

Connectivity & Integration

Professional balanced connectivity includes 2 x XLR and 2 x TRS inputs plus 2 x XLR outputs, allowing the LSR310S to connect to any studio monitor system or surround-sound configuration. The -10dBV/+4 dBu sensitivity switch ensures compatibility with both consumer and professional-level equipment without risk of input overload, while the 200 W Class D amplifier delivers sustained power without thermal stress.
