The JBL 310S MkIII extends the performance of the JBL 3 Series MkIII monitoring system with deep, controlled low-frequency reproduction engineered for today’s music production, content creation, post-production, and immersive audio workflows.

Featuring a redesigned 10-inch low-frequency driver, patented Slipstream™ port, powerful 300-watt Class D amplification, and flexible crossover management, the 310S MkIII delivers authoritative bass extension down to 26 Hz (-10 dB) while maintaining the accuracy and transient response demanded by professional production environments.

The redesigned acoustic platform combines a newly engineered 10-inch low-frequency driver, advanced magnetic system, patented Slipstream™ port, and downward-firing cabinet architecture to deliver deeper extension, greater output capability, and exceptionally controlled bass reproduction. Whether producing music, mixing film, or monitoring immersive content, the 310S MkIII reproduces the lowest octave with remarkable clarity, impact, and precision.

Selectable crossover frequencies at 80 Hz, 100 Hz, and 120 Hz allow the 310S MkIII to integrate seamlessly into a wide range of professional monitoring systems, while an external crossover bypass option provides compatibility with dedicated bass management systems. Professional balanced inputs make connection to audio interfaces, monitor controllers, and immersive monitoring systems straightforward.

A newly designed 300-watt Class D amplifier provides exceptional low-frequency headroom with ultra-low self-noise and outstanding dynamic performance. Combined with the redesigned 10-inch driver, the amplifier delivers up to 116 dB peak SPL, producing clean, controlled bass at every playback level without sacrificing definition or musicality.
