Twin C-CAM bass drivers, twin ABRs (Auxiliary Bass Radiators) and a single C-CAM tweeter in the centre section to provide the SB-3 with higher acoustic output and power handling for critical centre channel reproduction. This is combined with individual mid-bass, tweeter and sealed ABR drivers for both left and right channels.

In larger rooms the SB-3 can be used with a partnering Monitor Audio subwoofer to deliver the best possible audio experience. Within smaller environments and systems, the SBs will deliver effortless full range audio way beyond the limits of any TV's sound system.
