Monitor Audio Radius 390 Subwoofer, Walnut
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' in form and function. A system of twin colour-coded 10" C-CAM active/ABR drivers is powered by a 220W Class D amplifier to expand levels of output and 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. Enjoy rapid EQ optimisation from Impact, Music and Movie settings, and system automation via the 12V trigger.

18mm MDF cabinet construction with internal bracing

Cool-running 220W Class D amplifier with switch mode power supply (SMPSU)

Twin side-firing 10" C-CAM drivers - one active and one passive ABR

Low pass filter switch for LFE or Stereo input selection

Power switch with On-Auto-Off / trigger settings

Stereo / LFE RCA inputs

3 x Pre-set EQ settings - Music/Movie/Impact

C-CAM Bass Drivers

Refined over many years by Monitor Audio, Ceramic-Coated Aluminium/Magnesium is used as a driver cone material for all our speaker designs from the mid-market models up. Originally developed by the aerospace industry for jet engine components, C-CAM's properties are ideal for loudspeaker cones being extremely rigid, yet light enough to yield high overall efficiency. C-CAM bass drivers are able to resist the bending distortion imposed by sudden and extreme bass excursions to reproduce very clean, deep and dynamic bass frequencies. Conventional cone materials are more likely to flex in operation, producing a significant level of audible distortion.

ABR

For open environments sound quality can be further enhanced through the use of a sealed ABR (Auxiliary Bass Radiator). The ABR works like a piston moving back and forth generated by the movement of the air via the motion of the mid/bass driver inside the sealed cabinet. This makes the ABR ultimately act like a conventional port resulting in superior low frequency punch and extra penetration whilst keeping the elements at bay.
