Building on JBL's rich legacy of innovation, the 308P MkII features groundbreaking technologies such as the patented Image Control Waveguide and next-generation transducers, delivering an unparalleled listening experience. With an enhanced 8-inch low-frequency woofer and a 1-inch soft-dome high-frequency tweeter, the 308P MkII offers deep, accurate bass, soaring highs, and a perfectly balanced frequency response. The dual integrated Class-D power amplifiers, custom-designed by JBL for each transducer, provide a total of 112 watts of power, ensuring dynamic range and exceptional clarity at any volume level. Whether you're producing music, recording podcasts, designing sound for film, or vlogging, the JBL 308P MkII offers the output and performance you need to make precise, informed decisions in your mixes.

The 308P MkII features a new Boundary EQ that compensates for low-frequency variants caused by placement on desktops or near walls, making it highly adaptable to various studio environments. The 3-position HF Trim switch allows for fine-tuning of the high-frequency response, enabling you to adjust the speaker's output to suit your room acoustics or personal preference. This flexibility ensures that your mixes are accurate and consistent, even in non-ideal spaces. The JBL Image Control Waveguide, originally developed for the M2 Master Reference Monitors, ensures an acoustically seamless transition between the low and high-frequency drivers, providing an immersive soundstage with exceptional imaging. This feature guarantees that the 308P MkII reveals even the most subtle details of your mix, whether you're listening directly on-axis or from an off-axis position.

With a frequency range extending from 37 Hz to 24 kHz (-10 dB) and a maximum peak SPL of 112 dB, the JBL 308P MkII provides an expansive dynamic range, making it suitable for both low-level monitoring and high-volume applications. Whether you're mixing or mastering, you can rely on the 308P MkII to deliver accurate representation across the full frequency spectrum. The monitor's ported enclosure design, made from 15 mm MDF and finished with matte black PVC, ensures durability while maintaining a sleek, professional appearance. With flexible connectivity options, including balanced XLR and 1/4" TRS inputs, and an adjustable volume control, the 308P MkII integrates seamlessly into any production environment. The 308P MkII is rigorously tested, passing JBL's 100-hour full-power test, ensuring reliable performance for years to come.
