Monitor Audio SB-4 Passive 3-Channel Home Theater Soundbar

Monitor Audio SB-4 soundbar

The Monitor Audio SB-4 is the largest soundbar in the Monitor Audio range, engineered to provide a true home cinema experience for televisions measuring 70 inches and above. Featuring advanced acoustic engineering and premium driver technology, the SB-4 delivers powerful, detailed, and distortion-free sound reproduction from a single enclosure while maintaining dedicated left, centre, and right channel separation.

The soundbar incorporates nine high-performance drivers and four Auxiliary Bass Radiators (ABRs) arranged across three discrete internal chambers. The centre channel features twin 4-inch C-CAM midrange/bass drivers, twin ABRs, and a dedicated 1-inch C-CAM Gold Dome tweeter, providing enhanced dialogue clarity, increased power handling, and higher acoustic output for critical vocal reproduction. The left and right channels each include twin 4-inch C-CAM drivers, a dedicated tweeter, and an ABR for balanced stereo imaging and controlled low-frequency performance.

Monitor Audio’s C-CAM driver technology combines lightweight construction with exceptional rigidity, minimizing distortion while delivering accurate and detailed audio reproduction across the frequency range. The horn-loaded C-CAM Gold Dome tweeters provide wide and consistent dispersion, ensuring uniform sound coverage throughout the listening area.

The ABR-loaded design utilizes racetrack-style passive radiators to enhance bass response, increase power handling, and eliminate unwanted air turbulence. Combined with the internally braced MDF cabinet construction, this results in clean, controlled, and highly articulate audio performance.

Designed for both shelf and wall-mounted installations, the SB-4 includes integrated silicon feet and supports optional wall-mount brackets. It can also be partnered with a powered subwoofer and surround speakers to create a more immersive multi-channel home cinema system. Combining premium materials, advanced acoustic technologies, and powerful three-channel performance, the Monitor Audio SB-4 delivers exceptional television and movie sound reproduction.
