Product Description
The JBL 310S MkIII is a powered 10 inch studio subwoofer designed to extend the low frequency performance of the 3 Series MkIII monitoring system. It provides a dedicated low frequency foundation for 2.1, surround and immersive monitoring configurations, making it suitable for modern music, video and content production.
Features
- 10 Inch Powered Subwoofer - The 310S MkIII provides extended low frequency monitoring with a 26 Hz low frequency extension and 116 dB peak SPL.
- 300 W Class D Amplification - The dedicated Class D amplifier provides substantial power and headroom for demanding monitoring and production environments.
- Flexible System Expansion - The subwoofer adds low frequency extension and bass management for 2.1, surround and immersive monitoring configurations.
Extended Low Frequency Monitoring:
The 310S MkIII is designed to add deeper low frequency extension to a 3 Series MkIII monitoring system. Its 10 inch powered subwoofer design reaches down to 26 Hz at -10 dB, allowing producers and engineers to monitor low frequency content that may not be fully represented by full range studio monitors alone. With a peak SPL of 116 dB, the 310S MkIII is designed to deliver substantial output while maintaining the headroom required for modern production environments. It can be integrated into a 2.1 system or used as part of more advanced monitoring configurations.
Built for Modern Studio Configurations:
The 310S MkIII provides a flexible foundation for expanding a monitoring system beyond conventional stereo operation. It adds low frequency extension and bass management capabilities for 2.1 setups, while also supporting surround and immersive monitoring workflows. This makes it suitable for studios producing music, video, games and other content where accurate low frequency monitoring is important. Used alongside the 305P MkIII, 306P MkIII or 308P MkIII, it forms part of a consistent 3 Series MkIII family designed to scale as monitoring requirements develop.
Powerful Low Frequency Foundation:
At the centre of the 310S MkIII is a 300 W Class D amplifier designed to provide the power required for dedicated low frequency reproduction. Its 10 inch powered subwoofer configuration combines substantial output with extended bass response, helping provide a fuller monitoring experience when paired with compatible full range monitors. The 310S MkIII is designed to integrate into a range of studio layouts, providing additional low frequency capability without requiring a complete change to the existing monitoring platform.
