JBL LSR310S MK3 — 10" Powered Studio Subwoofer for Critical Low-End Monitoring

The JBL LSR310S MK3 is a 10-inch powered studio subwoofer built to anchor the bottom octave of any nearfield monitoring rig. A redesigned high-excursion down-firing driver paired with a 300 W Class-D amplifier pushes usable response down to 26 Hz, giving mix engineers a true picture of kick drums, bass guitars, and sub-frequency effects. With up to 116 dB peak SPL, the LSR310S MK3 keeps up with loud sessions without turning low-end translation into a guessing game.

Patented Slip Stream™ Port and Down-Firing Architecture

JBL's double-flared Slip Stream™ port reduces turbulence for tight, articulate bass at every playback level. The downward-firing driver orientation delivers more uniform dispersion while reducing unwanted boundary interaction, so the sub can be placed closer to walls without sacrificing accuracy.

Driver Power and Amplification

A 300 W Class-D amp drives a 250 mm high-excursion driver.

• LF Driver: 250 mm (10") high-excursion, down-firing — long-throw cone for clean output at high SPL
• Amplifier Power: 300 W Class-D — high headroom with cool, efficient operation
• Maximum Peak SPL: 116 dB

Low-Frequency Extension and Crossover Flexibility

Reaching 26 Hz at -10 dB, this sub reproduces the sub-bass region where kick fundamentals and cinematic LFE live. Four crossover settings tune the handoff to main monitors.

• Frequency Range: 26 Hz – 480 Hz (-10 dB) — full coverage of the sub-bass region
• Frequency Response: 27 Hz – 370 Hz (±3 dB) — flat enough for translation-critical mixing
• Crossover Settings: 80 Hz / 100 Hz / 120 Hz / External bypass
