About: JBL 305P MkIII Powered 5" Two-Way Studio Monitor (Each) 

Professional Monitoring Built for Modern Production

JBL 305P MkIII delivers the next generation of JBL professional studio monitoring, combining newly engineered HF and LF drivers, patented acoustic technologies, intelligent DSP room tuning, and ultra-low-noise Class D amplification into a compact reference monitor designed for today’s music creators, engineers, and content producers. With a frequency response extending down to 45 Hz (-10 dB) and up to 38 kHz, wide 120° x 90° coverage, and peak output of 109 dB SPL, 305P MkIII provides the accuracy, dynamics, and confidence needed to create mixes that translate everywhere.

Best-in-Class Acoustics

The completely redesigned acoustic platform combines a new high-performance silk dome tweeter, advanced low-frequency driver, JBL’s patented Image Control Waveguide, and patented Slipstream™ port to deliver exceptional clarity, precise imaging, extended low-frequency performance, and remarkably consistent off-axis response. Whether mixing at the sweet spot or collaborating across the room, 305P MkIII produces an accurate stereo image and natural tonal balance that help every mix translate with confidence.

DSP Room Optimization

Every room is different. Four onboard DSP controls allow users to quickly optimize monitor performance for desktop, stand, or wall placement while adjusting boundary compensation and high- and low-frequency response. With 81 configurable room tuning combinations, 305P MkIII adapts easily to home studios, professional control rooms, edit suites, and immersive production environments.

Powerful, Low-Noise Performance

A newly designed bi-amplified 86-watt Class D amplifier system (43 W LF + 43 W HF) delivers impressive output, wide dynamic range, and ultra-low self-noise for professional monitoring at any listening level. Capable of producing up to 109 dB peak SPL, the system maintains exceptional clarity during critical mixing while providing ample headroom for demanding production sessions.
