The JBL 308P MkIII delivers flagship performance for producers, engineers, and content creators who demand greater low-frequency extension, higher output, and uncompromising accuracy. Combining JBL’s next-generation transducer platform with patented acoustic technologies, intelligent DSP room optimization, and powerful bi-amplified Class D performance, the 308P MkIII provides the confidence needed to make critical mix decisions in larger production spaces.

With low-frequency extension down to 41 Hz (-10 dB), a maximum peak output of 113 dB SPL, and wide 120° x 90° coverage, the 308P MkIII delivers full-range monitoring with exceptional dynamics and precision.

The redesigned acoustic platform combines a new high-performance silk dome tweeter, advanced 8-inch low-frequency driver, JBL’s patented Image Control Waveguide, and patented Slipstream™ port to deliver outstanding clarity, controlled low-frequency performance, and exceptionally accurate stereo imaging. Designed for critical monitoring, the 308P MkIII reveals fine detail while maintaining consistent tonal balance across a wide listening area.

Four onboard DSP controls allow users to quickly optimize monitor performance for desktop, stand, or wall placement while adjusting boundary compensation and high- and low-frequency response. With 81 configurable room-tuning combinations, the 308P MkIII adapts easily to project studios, professional control rooms, educational facilities, and immersive audio environments.

A newly designed bi-amplified 110-watt Class D amplifier system, with 55 watts for the LF driver and 55 watts for the HF driver, delivers exceptional dynamic range, ultra-low self-noise, and powerful transient performance. Capable of producing up to 113 dB peak SPL, the 308P MkIII provides the headroom required for high-energy music production, cinematic content, and critical monitoring without sacrificing accuracy or detail.
