JBL 305P MkII-UK 5-Inch Powered Studio Monitor for Audio Production

The JBL 305P MkII-UK is a powered 5-inch two-way studio monitor engineered for professional-grade audio performance, ideal for music production, mixing, podcasting, and critical listening. Built by JBL—a brand with over 70 years of audio expertise—this monitor integrates technologies from the acclaimed 7 Series and M2 Master Reference Monitors, delivering exceptional sound quality at an affordable price. Tailored for the UK market, it includes a Type G power cord (230V, 50Hz) while maintaining the core features of the global 305P MkII model.

Part of the 3 Series MkII lineup, the JBL 305P MkII-UK combines a 5-inch woven-composite woofer and a 1-inch neodymium tweeter, powered by dual 41W Class-D amplifiers (82W total). This bi-amplified design ensures high output and a dynamic range, with a peak SPL of 108 dB. The patented Image Control Waveguide—originally developed for JBL’s flagship M2—creates a wide, room-friendly sweet spot with precise stereo imaging, allowing users to hear every detail, even off-axis. The Slip Stream™ low-frequency port enhances bass clarity, delivering tight, undistorted lows down to 43 Hz.

Next-generation transducers provide a neutral, transparent sound: the woofer offers deep, controlled bass with reduced distortion, while the tweeter ensures crisp highs with fast transient response. For room adaptability, the monitor features a Boundary EQ switch to manage low-end buildup near walls and a 3-position HF Trim (-2 dB, 0 dB, +2 dB) to tweak high frequencies. Connectivity is flexible with balanced XLR and 1/4" TRS inputs, plus an input sensitivity switch (+4 dBu/-10 dBV) for compatibility with various audio sources.

Housed in a sleek MDF enclosure (11.75" H x 7.3" W x 9.1" D, 4.73 kg), the 305P MkII-UK is built to last, undergoing JBL’s rigorous 100-hour full-power test. Its frequency range spans 43 Hz to 24 kHz, with a ±3 dB response from 49 Hz to 20 kHz, making it perfect for nearfield monitoring in small studios or home setups. Whether you’re producing tracks, editing podcasts, or enjoying multimedia, this monitor delivers stunning detail and accuracy.

What’s Included: 1x JBL 305P MkII-UK monitor, 1x UK power cord, quick setup guide (audio cables sold separately). Pair it with a subwoofer like the JBL LSR310S for extended bass if needed. Affordable yet powerful, this monitor is a top choice for UK audio enthusiasts and professionals.
