JBL 308P MkII Powered 8" Two-Way Studio Monitor

The JBL 308P MKII is a studio monitor with an 8 inch woofer, a 1 inch tweeter, and built-in amplifiers that reveal every nuance of your mix. Dual 56 watt amplifiers provide a total of 112 watts of power, covering a frequency range from 45 Hz to 20 kHz and reaching a peak level of 112 dB without strain.

An Image Control Waveguide shapes the high-frequency dispersion so you hear precise stereo placement even when you move around the room. The wide listening window lets a producer, artist, or client sit off axis and still catch the same detail and depth of the mix.

Low-end response is managed by a Slip Stream port that works with the woofer to keep bass punchy and defined. When the monitor sits close to walls or on a desk, a boundary EQ switch helps tame extra low-frequency buildup, while a three-position high-frequency trim lets you match the top end to the acoustics of different rooms.

Balanced XLR and 1/4 inch TRS inputs connect easily to audio interfaces, mixers, or outboard gear, and a sensitivity switch handles both professional and consumer line levels. These options allow the 308P MKII to slot into home studios, project rooms, educational labs, and broadcast suites without extra adapters.

Each component is tested under rigorous JBL standards, giving you a monitor that stays reliable through long sessions and regular transport. Whether you are tracking vocals, editing podcasts, designing sound for video, or approving a final master, the 308P MKII provides a clear reference you can trust.
