Monitor Audio SB-3 One Box LCR Speaker System
The SB-3 from Monitor Audio has been designed to offer the convenience of a typical soundbar – easy installation, less clutter and discrete appearance whilst still giving customers the performance and flexibility of a complete AV system.
The SB-3 is custom-built for screen sizes above 60″ and features three separate driver arrays for front left, centre and front right channels, all in a single stylish cabinet. The important centre channel section includes twin C-CAM bass drivers, twin ABRs (Auxiliary Bass Radiators) and a single C-CAM tweeter to help provide the SB-3 with higher acoustic output and power handling. The left and right sections each employ individual mid-bass, tweeter and sealed ABR drivers.
Braced for maximum rigidity and further strengthened by Monitor Audio’s innovative bolt-through driver mountings, the SB-3’s high-density cabinet is finished with an acoustically transparent cloth and capped at either end with stylish brushed aluminium finials for a beautifully discreet designer look that will complement the style of any flat screen display.
High quality, low profile terminals are recessed to facilitate flush-to-wall installation (when using the optional low profile wall mount bracket) allowing for easy cable access, pre-alignment and fixing. Integrated Silicon feet provide a secure, stable base should you want to sit the SB-3 on top of a cabinet or shelf.
It is also very easy to upgrade the SB-3 to a full 5.1 home theatre system simply by adding an active subwoofer and a pair of rear speakers – choose from on-wall, in-ceiling or floorstanding models to complement your decor.
