The JBL 308P MKII is a bi-amplified, powered 8-inch two-way studio monitor for tracking, mixing and post. Dual 56 W Class-D amplifiers drive an 8-inch low-frequency woofer and a 1-inch woven-composite neodymium tweeter for a combined frequency response of 45 Hz to 20 kHz and a peak SPL of 112 dB. JBL's Image Control Waveguide keeps imaging precise across a wide sweet spot, while the Slip Stream port design supports low-frequency extension. The cabinet is magnetically shielded, a boundary EQ tames the low end when the monitor sits close to a wall, and a three-position HF trim switch matches it to the room. Balanced XLR and quarter-inch TRS inputs with a selectable input-sensitivity switch make it straightforward to drop into a modern workspace, whether a solo edit room or a multi-room facility.
