JBL 310S MKIII
Estimated delivery in Italy between 16 and 18 November
10" active subwoofer
The JBL 310S MkIII is the dedicated 10" subwoofer for the 3 Series MkIII. It allows a pair of monitors to be extended into a full-range 2.1 system and supports bass management for surround workflows and immersive audio, ensuring the low-frequency confidence that studio monitors alone cannot offer. The new 10" down-firing driver uses an advanced magnetic system to deliver controlled bass and uniform coverage throughout the listening environment. The patented JBL Slipstream front bass-reflex port reduces resonances and air noise, keeping the low end defined and articulate even as the volume increases. The 310S MkIII delivers low-frequency extension down to 26 Hz (-10 dB), while the built-in 300W Class D amplifier delivers an output level of up to 116 dB peak SPL. The main strength of the 310S MkIII is its ease of integration: the selectable crossover settings at 80 Hz, 100 Hz, and 120 Hz make configuring a 2.1 system immediate, while the external crossover (bypass) mode allows dedicated bass management systems to handle the frequency cut-off in surround or immersive configurations. The improved phase alignment compared to the previous generation ensures a smoother and more natural transition to the main monitors. For those who own the JBL 305P, 306P, or 308P monitors, the 310S MkIII subwoofer represents the natural extension of the system to complete the listening station and make accurate decisions across the entire frequency spectrum.
