308P MkII 8" 2-Way Powered Studio Reference Monitor Monitoring Speaker

The JBL 308P MkII takes the 3 Series design up to an 8-inch woofer, giving studios that need full-range low-frequency response a monitor that does not require a separate subwoofer for most program material. The Image Control Waveguide, adapted from the flagship M2 Master Reference Monitor, aligns the woofer and 1-inch woven-composite Neodymium tweeter for a broad sweet spot and precise imaging across the room. Dual Class D amplifiers deliver 112 watts of total bi-amplified power, and the larger 8-inch driver extends bass reproduction down to 37 Hz, giving mixes more accurate low-end information than smaller monitors in the same line.

A patented Slip Stream low-frequency port supports that extended bass response, while new Boundary EQ settings and a 3-position HF Trim switch let you tune the monitor’s output for desktop or stand placement and room acoustics. Balanced XLR and 1/4-inch TRS inputs with switchable +4dBu/-10dBV sensitivity connect to professional or consumer-level gear without an adapter. Every 308P MkII passes JBL’s 100-hour full-power reliability test before shipping, confirming it can handle sustained studio use. For mastering, film and post work, or any mix that depends on accurate low-end detail, the 308P MkII is the largest, most full-range monitor in the 3 Series lineup.
