PMC BST: The Most Powerful Subwoofer Ever Made by PMC

The PMC BST is the most advanced passive subwoofer in the PMC range. Designed to enhance the extension and low-frequency dynamics of QB1 and XBD professional monitoring systems, it offers a frequency response down to 17Hz with a continuous sound pressure of 120dB, while maintaining an extremely low level of distortion.

Extreme Performance with ATL™ Technology

With its 4.5-meter-long ATL™ transmission line, the BST is able to generate deep, controlled low frequencies. The 15" unit handles linear excursions of ±20mm and maximums of ±40mm, supported by a 7.4" coil with a high-efficiency ferrite magnet, capable of handling 2500W RMS continuously.

Inertial Cabinet and LaminairX

The cabinet structure, with 36mm-thick panels and internal bracing, ensures inertia even at high pressures. The LaminairX system reduces air turbulence and harmonic distortion by up to 3dB, ensuring precise time response and exceptional dynamic range.

Installation Flexibility

Being passive, the BST can be installed in freestanding, in-wall or ceiling configurations. It is the perfect addition to any high-performance PMC system, whether in stereo, cinema or studio multichannel configuration.
