How low does the LSR310S reach, and how loud can it get?

The subwoofer extends low-frequency response to 27 Hz with a maximum peak SPL of 113 dB, powered by a 200 W Class D amplifier. This combination delivers both deep extension for hearing all your bass content and sustained output suitable for professional mixing and mastering spaces.

What crossover options does it have, and how do I integrate it with my monitors?

The LSR310S offers three crossover modes: 80 Hz (standard), XLF (a club-inspired tuning that emulates professional dance-venue bass), and External (for use with an external crossover or monitor controller). It has 2 x XLR and 2 x TRS balanced inputs plus 2 x XLR outputs, so it works with any professional monitoring system.

Will it work with both consumer and pro-level equipment?

Yes—the selectable input sensitivity switch toggles between -10dBV (consumer) and +4 dBu (professional) to match your source devices without risk of overload. The maximum peak input level is +20.3 dBu.

What are the dimensions and weight?

The LSR310S measures 448 x 381 x 398 mm and weighs 15.6 kg (34.3 lbs), making it compact enough for most studio setups while housing a 250mm high-excursion driver.

Is this suitable for live sound or mobile use?

No—the LSR310S is designed exclusively for studio monitoring, mixing, and mastering. It is not rated for live performance or portable applications.

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

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.
