JBL 306P MkII Powered 6.5" Two-Way Studio Monitor

The JBL 306PMKII is a powered two-way studio monitor designed to give you an honest picture of your mix. A 6.5-inch woofer works with a 1-inch tweeter, each driven by its own 56-watt Class-D amplifier, so you hear deep lows, articulate mids, and clear highs without strain.

JBL’s patented Image Control Waveguide shapes the high-frequency dispersion, letting you move around the room and still trust what you hear. For producers who need solid low-end at moderate volumes, the Slip Stream rear port keeps bass tight and musical rather than boomy.

No two rooms sound the same, so the monitor includes boundary EQ switches that tame low-frequency buildup near walls, along with a high-frequency trim that lets you fine-tune the top end. Balanced XLR and ¼-inch TRS inputs make it easy to connect an audio interface or mixer, and an input-sensitivity switch matches consumer or professional signal levels.

Whether you are mixing a full song, editing dialogue for video, or tracking vocals in a bedroom studio, the 306PMKII delivers the detail you need. The monitor can reach 110 dB SPL while covering a wide 39 Hz to 24 kHz frequency range, so you can hear subtle reverb tails and deep kick drums without a subwoofer. Each unit also passes JBL’s 100-hour power test, giving you confidence that it will handle long sessions day after day.
