JBL Professional JBL 306P MkII Powered two-way studio monitor, bi-amplified
The 306P MkII is the middle monitor in the 3 Series MkII line: a 6.5-inch woofer and a 1-inch soft-dome tweeter on 56 W of Class D power each, crossed at 1,425 Hz. Response is 47 Hz to 20 kHz within 3 dB with 110 dB peak output. The Image Control Waveguide is the reason these monitors sound the way they do off-axis: it is the same geometry JBL developed for the M2 master reference monitor, and it keeps the stereo image stable when you move out of the exact sweet spot. Coverage is 120 degrees horizontal by 90 degrees vertical.
Rear-panel controls include an HF trim of -2, 0 or +2 dB and a boundary EQ shelf at 50 Hz for -3, -1.5 or 0 dB, which is what you use when the monitor has to sit close to a wall. Inputs are balanced XLR and TRS. The cabinet is 15 mm MDF in matte black PVC with an injection-moulded ABS baffle. The extra half-inch of cone over the 305P shows up as a little more low end and headroom for the same desk footprint.
