Product Description
The JBL 305P MkIII is a professionally focused powered studio monitor designed to deliver accurate, detailed sound for music production, recording, mixing and content creation. As part of the comprehensively redesigned 3 Series MkIII family, it combines a new acoustic system with transparent electronics, straightforward room correction and flexible placement options.
At its heart is a redesigned high-frequency driver working alongside the improved JBL Image Control Waveguide, helping deliver a wide and consistent listening area with precise stereo imaging and a stable phantom centre. The redesigned 5-inch low-frequency driver uses stiffer cone materials, an upgraded magnet assembly and an aluminium shorting ring to improve power handling and reduce distortion.
The front-firing JBL Slipstream port helps make bass response more predictable when the 305P MkIII is positioned on a desk, monitor stand or closer to a wall. Four one-touch EQ controls provide 81 corrective EQ combinations for adapting the monitor to its placement and room. A new Class D amplifier delivers 86 W of power with increased headroom and lower system noise, while balanced Neutrik combo inputs and selectable sensitivity make integration with studio equipment simple.
Features
- Redesigned Acoustic System - A new high-frequency driver, low-frequency driver and JBL Image Control Waveguide provide detailed sound, wide coverage and precise stereo imaging.
- 81 Room EQ Combinations - Four one-touch controls provide practical correction for placement, boundary distance and high- or low-frequency adjustments without software.
- Front Firing Slipstream Port - The front firing port helps provide more predictable low frequency performance when positioned on desks, stands or near walls.
Detailed Stereo Monitoring:
The 305P MkIII is designed to provide a clear and consistent monitoring experience across a wider working area. Its redesigned high-frequency driver works with the improved JBL Image Control Waveguide to create a broad listening window while maintaining detailed stereo imaging and a stable phantom centre. The redesigned 5-inch low-frequency driver uses stiffer cone materials, an upgraded magnet assembly and an aluminium shorting ring to improve power handling and reduce distortion. Together, these acoustic refinements provide a balanced monitoring platform for recording, editing, mixing and everyday content production.
Simple Room Adaptation:
Every room and workstation presents different acoustic challenges, so the 305P MkIII includes four one-touch corrective EQ controls. These provide 81 possible EQ combinations to help compensate for common placement and room-related issues, including speaker position, distance from boundaries and high- or low-frequency response. This approach makes it easier to adapt the monitor without relying on measurement equipment, calibration software or complicated menus. The front-firing JBL Slipstream port also helps make low-frequency behaviour more predictable when the monitor is used on a desktop or positioned relatively close to a wall.
Flexible Studio Integration:
The 305P MkIII is designed to work across a wide range of modern studio environments. Its new Class D amplifier provides 86 W of power, delivering high output, additional headroom and lower system noise. Balanced Neutrik combo inputs support common studio connections, while selectable +4 dBu and -10 dBV sensitivity makes integration with different studio devices and playback systems straightforward. Eight M4 mounting points are built into the monitor, allowing elevated, inverted or side-firing installation where required. This makes the 305P MkIII suitable for compact stereo systems as well as larger monitoring configurations.
