About: JBL 306P MkIII Powered 6" Two-Way Studio Monitor (Each) 

Professional Monitoring for Growing Production Spaces

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 to 43Hz (-10 dB), 112 dB peak SPL, and wide 120° × 90° coverage, 306P MkIII delivers the headroom, accuracy, and dynamic range required for larger rooms and more demanding productions.

Best-in-Class Acoustics

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. Whether mixing music, editing content, or producing immersive audio, 306P MkIII provides the detail and consistency needed to make confident mix decisions.

Intelligent DSP Room Optimization

Professional monitoring begins with adapting to the room. 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, 306P MkIII delivers consistent performance across home studios, professional control rooms, and production suites.

High Output. Low Noise.

A newly designed bi-amplified 110-watt Class D amplifier system (55 W LF + 55 W HF) delivers exceptional dynamic range, ultra-low self-noise, and outstanding transient performance. Capable of producing 112 dB peak SPL, 306P MkIII provides the output and headroom needed for accurate monitoring while maintaining the detail and precision demanded by today’s creators.
