150W Active Subwoofer with 20cm Cone

Boost your home theatre

Dedicated to music and movie lovers, the compact black S-51W subwoofer benefits from our technical know-how in designing both amplifiers and speakers.

It features a 20cm driver enclosed with a ‘down-fire’ bass-reflex type cabinet that inherits its stylish shape from our high-end Series 8 subwoofer.

Integrating a 150W RMS amplifier, it delivers enough power to support all speaker configurations from 2.1 to 7.1.

By complying with our Phase Control technology standards, it ensures a faithful reproduction of the original multi-channel source when combined with our AV receivers as they benefit from this proprietary technology.

Phase Control technology manages the time and phase response of the speakers to minimise the effect of additional sound delays usually due to the filtering process of multi-channel recordings.
