The JBL 310S MkIII Powered Studio Subwoofer delivers deep, controlled bass for music production, mixing, post-production and immersive audio workflows. Featuring a redesigned 10-inch low-frequency driver, JBL's patented Slipstream port and powerful 300-watt Class D amplification, it extends low-frequency response down to 26Hz for accurate monitoring of bass instruments, kick drums and cinematic effects.
Its downward-firing woofer design supports consistent bass dispersion, while the patented Slipstream port helps reduce turbulence for tight, articulate low-frequency reproduction. With selectable crossover settings at 80Hz, 100Hz and 120Hz, or an external-crossover bypass option, the 310S MkIII integrates flexibly into professional stereo, surround and immersive monitoring systems.
The 300-watt Class D amplifier delivers up to 116dB peak SPL with substantial headroom and low noise. Professional balanced Neutrik combo inputs provide convenient connectivity for audio interfaces, monitor controllers and other compatible studio equipment.
