The Fostex PM0.3d are a 2-way design with a 3-inch woofer and 3/4-inch tweeter. Sold as a pair and available in three colours - Black, Grey and White. The PM0.3d monitors offer surprisingly loud and clear frequency response for such a small unit. They are great as a secondary portable pair of monitors, spot speakers for live / theater use, or at home for personal use. The PM0.3d loudspeakers have an in-built D-class amplifier, that provides 15 watts each side (RMS). Fostex have also designed an active subwoofer, the PM-SUBmini2, to accompany the PM0.3d monitors.
