Radius 390 compact subwoofer


Promising the astonishing low frequency resolution of the 380 with the added depth, impact and control of a larger bass engine, the Radius 390 demolishes assumptions of size versus performance. With every earth-shaking transient, you’ll be more convinced that the compact 390 is truly ‘ground-breaking’ inform and function.


A system of twin colour-coded 10” C-CAM active/ABRdrivers is powered by a 220 W Class D amplifier to expand levels of outputand extension, releasing a rich layer of penetrating bass, mesmerising in its consistency and scale.


You’ll get agility as well, for rhythmic depth with music, and dynamic reinforcement in home theatre systems – all this from a beautiful little cube that liberates living space. In tune with Radius philosophy the 390 is perfect for lifestyle but sonically it’s in a class of its own.
