PMC 10-4 - Active Subwoofer

The PMC10-4 SUB is a dual-purpose product that serves either as an independent low-frequency subwoofer to supplement any PMC monitoring system or to augment a master PMC10-4 full-range monitor, creating the twin-cabinet PMC10-4 XBD system. Like its sibling models, the PMC10-4 SUB shares the latest-generation ATL™ Advanced Transmission Line cabinet with LaminairX™ airflow venting.

Featuring four innovative, in-house and custom-designed 10-inch bass drivers which feature a large excursion range to deliver an extended low-frequency performance across a remarkably wide bandwidth, resulting in ultra-low distortion at all monitoring levels.

When deployed as part of a twin-cabinet XBD system, the PMC10-4 SUB is powered by dual power20 amplifiers and seamlessly controlled by the existing master36.

In a standalone configuration, the 10-4 SUB is managed by the master36 DSP/Amplifier, delivering 1,000 watts to each of two bass drivers, while a linked power20 amplifier supplies a further 1,000 watts to each of the remaining pair—ensuring exceptional control, headroom, and low-frequency precision.

Both electronics packages employ ultra-transparent Class-D amplification, while the integrated DSP within the master36 provides transparent excursion limiting for system protection, along with precise room-optimisation EQ and digitally optimised high- and low-pass filters tailored specifically to the PMC10-4 SUB’s configuration and drivers.

The master36 accepts both analogue and digital inputs and can be controlled over a standard LAN via the SoundAlign2 browser-based interface. An illuminated front-panel logo provides a clear, at-a-glance indication of system status.
