The Monitor Audio Radius 380’s twin side-firing 8” C-CAM® drivers - one active and one passive ABR - work in tandem with a powerful 200W cool-running Class D amplifier (double the power of its predecessor).

The drivers have no grilles but are colour-coded to coordinate with cabinet finish.

A 12V trigger syncs the 380 with other AV components when the system is activated.
