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.

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.
speed, accuracy, musicality
In my opinion that this is the best subwarf from all the sabers presented by the Audio monitor (of course, we don’t take a series of Gold and Platino, there is a completely different price category) !!! The subwoofer is really musical !! Excellent choice, in terms of quality of the bass can be compared with the REL T7, in the direct comparison I find it difficult to make the choice of the OBI model very worthy !!!

Original reviews
From the very first speaker, the iconic MA1, the brand developed, innovated, designed and refined, with a pioneering approach that saw patent after patent filed. It’s an ethos that hasn’t changed at all. In fact, Monitor Audio is one of very few high-end audio brands still developing new, cutting-edge technologies today.
