Compact by design
Professional monitoring without sacrificing valuable workspace. JBL 305P MkIII brings the complete 3 Series MkIII redesign to the most compact model in the family, making it ideal for home studios, project studios, podcast rooms, edit bays, and creator workstations. Its space-efficient design fits comfortably on crowded desks while delivering the accurate, professional sound needed for confident mixing, editing, and content creation.

Precise imaging
Make critical listening decisions with greater confidence. A newly engineered high-frequency driver and redesigned JBL Image Control Waveguide create a wide, consistent listening area with precise stereo imaging, allowing mixes to translate more accurately. Instead of a narrow sweet spot, you'll experience reliable performance across your workspace, making it ideal for multi-screen setups, shared studios, and collaborative production environments.

Powerful, controlled bass
Hear deeper, cleaner low frequencies without sacrificing accuracy. A redesigned 5-inch woofer featuring stiffer cone materials, a new 20 oz magnet assembly, aluminum shorting ring, and JBL's patented front-firing Slipstream port delivers lower distortion, improved output, and bass extension down to 45 Hz. The front-firing port also keeps low-frequency performance more predictable when placed near walls or on desktops.

Room optimization made simple
Achieve accurate monitoring in virtually any production space with fast, intuitive adjustment. Four one-touch controls provide 81 corrective EQ combinations to compensate for speaker placement, wall proximity, and high- and low-frequency balance. Fine-tune your monitoring in seconds without software or complicated switches, helping your mixes translate consistently in almost any room.

Scalable from stereo to immersive
Build a monitoring system that evolves with your studio. Start with a stereo pair, add a JBL subwoofer for deeper low-frequency extension, then expand into surround or immersive monitoring as your production needs grow. Eight integrated M4 mounting points with a standard 75 × 75 mm pattern make desktop, wall-mounted, elevated, and inverted installations simple while maintaining consistent voicing across the entire 3 Series MkIII family.
