JBL Professional has introduced its new 3 Series MkIII family of powered studio monitors and subwoofers, featuring redesigned acoustic systems, new Class D amplification and updated room optimisation controls. The lineup includes the 305P MkIII, 306P MkIII and 308P MkIII studio monitors, alongside the 310S MkIII powered subwoofer.
Announced by HARMAN Professional Solutions, the new range represents the most extensive redesign of the 3 Series platform to date. It is aimed at music producers, video editors and content creators, with configurations suited to compact home studios as well as larger production spaces.
JBL 3 Series MkIII Gets Redesigned Acoustic Systems
The MkIII monitors feature redesigned high-frequency drivers paired with an updated JBL Image Control Waveguide, which is intended to deliver wider listening coverage and more consistent stereo imaging. The low-frequency drivers have also been updated with stiffer cone materials, improved magnet assemblies and aluminium shorting rings to reduce distortion. A front-firing JBL Slipstream port is designed to provide more predictable bass response, particularly when the monitors are placed close to walls or on desks.
New Class D Amplification And Room Optimisation Controls
All three full-range monitors feature new Class D amplification, balanced Neutrik combo inputs and selectable input sensitivity. They also include four one-touch room controls offering 81 corrective EQ combinations to adjust for speaker placement, wall distance and frequency balance, without requiring calibration software.
JBL 310S MkIII Subwoofer Extends Bass Response To 26Hz
The 305P MkIII features a 5-inch driver, while the 306P MkIII and 308P MkIII come with 6.5-inch and 8-inch drivers, respectively. The 310S MkIII is a 10-inch powered subwoofer that extends low-frequency response to 26Hz. It also includes selectable crossover settings and bass-management bypass.
Integrated M4 mounting points across the full-range models allow users to install them on walls, ceilings, stands or monitor arms, making it easier to build stereo, 2.1, surround and immersive audio setups.
The JBL Professional 3 Series MkIII range is available in Asia-Pacific, Europe, the Middle East and Africa from November 3, 2026. North American availability is scheduled for January 7, 2027. Pricing details for India have not been announced.
