JBL 308P MkII-EU 8-Inch Powered Studio Monitor

The JBL 308P MkII-EU is a next-generation, powered 8-inch two-way studio monitor engineered to deliver exceptional audio performance for both professional and home studio environments. Designed by JBL, a brand synonymous with professional audio excellence, this monitor combines cutting-edge technologies with refined components to offer stunning detail, precise imaging, a wide sweet spot, and an impressive dynamic range. It’s the perfect choice for music producers, audio engineers, and content creators who demand high-quality sound reproduction at an affordable price.

Key Features and Design

The JBL 308P MkII-EU features the patented Image Control Waveguide, a technology borrowed from the flagship JBL M2 Master Reference Monitor. This waveguide ensures accurate sound dispersion, delivering detailed imaging and a broad sweet spot that adapts to various listening positions and room layouts. Paired with next-generation transducers—an 8-inch long-throw woofer for deep, controlled bass and a 1-inch neodymium tweeter for crisp, clear highs—the monitor excels at revealing subtle nuances in mixes. The Slip Stream™ low-frequency port enhances bass response with minimal distortion, while dual 56W Class-D amplifiers (112W total) provide robust power and dynamic range for critical listening.

Performance and Customization

With a frequency response of 45 Hz – 20 kHz (±3 dB) and a maximum peak SPL of 112 dB, the 308P MkII-EU ensures neutral, reliable sound for mixing and mastering. The Boundary EQ adjusts low-end response (-3 dB, -1.5 dB, or 0 dB at 50 Hz) to compensate for room placement, while the HF Trim switch (-2 dB, 0 dB, +2 dB) fine-tunes highs to suit your space or taste. Flexible connectivity includes balanced XLR and 1/4" TRS inputs with a +4 dBu / -10 dBV sensitivity switch, ensuring compatibility with a range of gear.

Build and Reliability

Crafted from 15 mm MDF with a matte black PVC finish and an ABS baffle, the monitor’s ported enclosure is both durable and stylish. Measuring 419 mm x 254 mm x 308 mm and weighing 8.1 kg, it fits seamlessly into any studio. Each unit undergoes JBL’s 100-hour full-power test for guaranteed reliability, and its 100–240 VAC power compatibility suits EU and global standards.

Why Choose the MkII?

The MkII iteration improves upon the original 3 Series with enhanced transducers, better transient response, and new EQ options, making it more versatile and accurate. Whether for music production, podcasting, or video editing, the JBL 308P MkII-EU delivers professional-grade performance at an unbeatable value.
