Description
The JBL 306P MkIII is a powered 6.5-inch professional studio monitor designed for music production, content creation, post-production, and immersive audio workflows. Its redesigned acoustic platform combines a high-performance silk dome tweeter, advanced 6.5-inch low-frequency driver, patented Image Control Waveguide, and Slipstream port to deliver detailed imaging, controlled low-frequency response, and consistent off-axis performance. With a frequency range extending from 43 Hz to 38 kHz and 120° x 90° coverage, the 306P MkIII provides the accuracy and headroom needed for demanding production environments.
The monitor features a bi-amplified 110W Class-D amplifier system with 55W dedicated to the low-frequency driver and 55W to the high-frequency driver. Maximum RMS SPL reaches 100 dB, while maximum peak SPL reaches 112 dB for increased output and dynamic range. Four onboard DSP controls provide 81 configurable room-tuning combinations, allowing users to optimize performance for desktop, stand, or wall placement while adjusting boundary compensation and high- and low-frequency response. HF adjustment at 3 kHz and LF adjustment at 300 Hz each provide -2 dB, 0 dB, or +2 dB settings.
The 306P MkIII features a ported 15 mm MDF enclosure with a matte black PVC finish, injection-molded structural ABS baffle, and 2 mm SPCC rear panel. A balanced Neutrik Combo input provides professional analog connectivity, while M4 x 8 mounting points and a 75 x 75 mm VESA pattern support flexible installation. The monitor operates from 100–240 VAC and weighs 14.8 lbs, with cabinet dimensions of 14.6" x 8.3" x 11.4". Its combination of JBL acoustic technologies, DSP room optimization, high-output Class-D amplification, and flexible mounting makes the 306P MkIII suitable for home studios, professional control rooms, production suites, and immersive audio environments.
