JBL Professional JBL 308P MkII Powered two-way studio monitor, bi-amplified

The 308P MkII is the largest of the 3 Series MkII monitors: an 8-inch woofer and a 1-inch soft-dome tweeter, bi-amplified at 56 W each, crossed at 1,800 Hz. Response is 45 Hz to 20 kHz within 3 dB, and continuous output of 102 dB is a real step up from the 5 and 6.5-inch models. 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. At 17.9 lb these want a proper stand or a solid meter bridge rather than a desk shelf.
