Description
The PMC MB2S XBD Passive is a three-way, passive floor-standing studio monitor built on PMC's Advanced Transmission Line (ATL) cabinet design and intended for recording, mastering, and post-production in stereo or surround setups. It combines a main MB2S enclosure with a separate XBD bass-extension cabinet, giving two 310mm PMC Radial low-frequency drivers (one per cabinet) alongside a 75mm fabric-dome midrange and a 27mm fabric soft-dome tweeter. The added XBD cabinet increases low-frequency headroom by 3dB below 380Hz to drive larger rooms. Crossover points are 380Hz and 3.8kHz, handled by external 32-element, 4th-order passive crossover enclosures that can mount to the rear of the XBD cabinets. Being passive, it requires an external power amplifier and connects via three pairs of 4mm sockets for tri-wire or tri-amp operation.
