JBL 305P MKIII Powered 5-inch Two-Way Studio Monitor - Single

The JBL 305P MkIII Powered Studio Monitor delivers accurate, detailed sound for music production, mixing and content creation. Combining redesigned high- and low-frequency drivers, JBL's patented acoustic technologies, DSP room optimisation and low-noise Class D amplification, it provides precise stereo imaging and consistent performance in a compact, professional monitoring system.

Featuring a 5-inch low-frequency driver and a 1-inch silk dome tweeter, the 305P MkIII offers a frequency range extending from 45Hz to 38kHz (-10dB), with wide 120° x 90° coverage. Its patented Image Control Waveguide enhances imaging, while the Slipstream port supports clean, controlled bass. Four onboard DSP controls provide 81 room-tuning combinations to help optimise performance for different acoustic environments and monitor placements.

The bi-amplified 86-watt Class D system delivers up to 109dB peak SPL with low noise and ample headroom for critical listening. Finished in matte black, the monitor also features top and bottom mounting points for flexible installation in modern studio setups.
