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" low-frequency driver, patented Slipstream port, powerful 300W Class D amplification, and flexible crossover management, 310S MkIII delivers authoritative bass extension down to 26Hz (-10dB) while maintaining the accuracy and transient response demanded by professional production environments.
Best-in-Class Low-Frequency Performance
The redesigned acoustic platform combines a newly engineered 10" 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, 310S MkIII reproduces the lowest octave with remarkable clarity, impact, and precision.
Flexible System Integration
Designed to integrate seamlessly into professional monitoring systems, 310S MkIII features selectable crossover frequencies at 80Hz, 100Hz, and 120Hz, or can be bypassed for use with external bass management systems. Professional balanced inputs simplify connection to audio interfaces, monitor controllers, and immersive monitoring systems, providing the flexibility required for stereo, surround, and Atmos production environments
Powerful Bass. Professional Control
A newly designed 300W Class D amplifier provides exceptional low-frequency headroom with ultra-low self-noise and outstanding dynamic performance. Combined with the redesigned 10" driver, the amplifier delivers up to 116dB peak SPL, producing clean, controlled bass at every playback level without sacrificing definition or musicality.
