JBL Launches 3 Series MkIII Studio Monitor Family
The redesigned lineup adds a new subwoofer and room-correction controls, with North American availability set for January 7, 2027.
Updated on Nov. 4, 2026 in Home Entertainment
JBL Professional has introduced the 3 Series MkIII family, including the 305P MkIII, 306P MkIII and 308P MkIII powered studio monitors and the 310S MkIII powered subwoofer. The lineup features re-engineered acoustics, Class D amplification and updated drivers across all models.
Why it matters
The redesign targets studio and home production users who need predictable bass and simpler room setup. Availability in North America begins January 7, 2027, with the family already offered in Asia-Pacific, Europe and the Middle East and Africa.
The four one-touch room controls on each full-range model offer 81 corrective EQ combinations for placement and wall-distance adjustment. The 310S MkIII subwoofer extends its low-frequency response to 26 Hz, while input sensitivity can be switched between +4 dBu and -10 dBV.
The players
JBL Professional
JBL Professional is the professional audio division of Harman, known for studio monitors and live sound equipment used in recording and broadcast environments.
The details
The 3 Series MkIII lineup pairs a redesigned high-frequency driver with an updated JBL Image Control Waveguide, and the low-frequency drivers use stiffer cones, upgraded magnets and aluminum shorting rings. A new port design is intended to deliver more consistent bass when the monitors sit near walls or on desks.
Timeline
November 3, 2026: JBL announces the 3 Series MkIII family and 310S MkIII subwoofer.
January 7, 2027: The lineup becomes available in North America.
Product Lineage
The MkIII release continues JBL's 3 Series monitor line, updating its drivers, amplification and room controls while keeping the family's compact desktop format. It shows a broader push among pro audio makers to make monitors easier to place in untreated home and project rooms.
Buyers in North America can order the 3 Series MkIII monitors and 310S MkIII subwoofer starting January 7, 2027, while buyers elsewhere can already purchase the family in Asia-Pacific, Europe and the Middle East and Africa. The room controls and mounting options are aimed at users who want to set up monitors without extensive acoustic treatment.
The takeaway
Users setting up monitors in ordinary rooms can use the four one-touch room controls, which offer 81 corrective EQ combinations, to adjust for wall distance and placement. Checking the input sensitivity setting before connecting gear will help avoid level mismatches.
