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. These controls allow producers and engineers to tailor sub integration to their room acoustics and mix requirements.
Connectivity & Studio Workflow
Professional balanced connectivity includes 2 x XLR and 2 x TRS inputs plus 2 x XLR outputs, enabling the LSR310S to fit into any studio monitor architecture—from stereo monitoring through surround setups. The -10dBV/+4 dBu sensitivity switch ensures smooth operation with both consumer and professional-level gear without input overload concerns, while the 200 W Class D amplifier delivers consistent power across long mixing and mastering sessions without thermal fatigue.
