JBL 310S MKIII 10" Powered Subwoofer (Each)

Get the low-frequency reach you need and the power to drive it with the LSR310S MkIII subwoofer. Extending response down to 26 Hz with a redesigned 10-inch driver and then powering it with a 300-watt Class D amplifier, its downward-firing cabinet and JBL's Slipstream™ port help deliver deep, controlled bass with the impact and definition you need to judge everything from kick drums and bass guitars to cinematic effects in the lowest octave of immersive mixes. With up to 116 dB peak SPL, it has the headroom to keep up when your session gets loud without turning the bottom end into a guessing game.

Integration stays flexible with selectable crossover points at 80, 100, or 120 Hz, plus a bypass setting for systems using external bass management. Balanced inputs make it easy to connect the 310S MkIII to an audio interface, monitor controller, or immersive monitoring system, with support for stereo, surround, and Atmos® production setups. The redesigned driver, magnetic system, and low-noise amplification work together to deliver bass that hits with authority while staying controlled enough for critical mixing.
