The JBL 306P MkIII combines JBL’s next-generation acoustic platform with increased output capability, deeper low-frequency performance, and intelligent DSP room optimization to deliver trusted reference monitoring for music production, content creation, post-production, and immersive audio workflows.

With low-frequency extension down to 43 Hz (-10 dB), a maximum peak output of 112 dB SPL, and wide 120° x 90° coverage, the 306P MkIII delivers the headroom, accuracy, and dynamic range required for larger rooms and more demanding productions.

The redesigned acoustic platform combines a new high-performance silk dome tweeter, advanced 6.5-inch low-frequency driver, JBL’s patented Image Control Waveguide, and patented Slipstream™ port to deliver exceptional clarity, controlled low-frequency response, and remarkably accurate stereo imaging.

Four onboard DSP controls provide fast optimization for desktop, stand, or wall placement while allowing users to fine-tune boundary compensation and high- and low-frequency response. With 81 configurable room-tuning combinations, the 306P MkIII delivers consistent performance across home studios, professional control rooms, and production suites.

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 outstanding transient performance. Capable of producing up to 112 dB peak SPL, the 306P MkIII provides the output and headroom needed for accurate monitoring while maintaining the detail and precision demanded by today’s creators.
