Description
Monitor Audio SB-3 Passive Soundbar
Passive three-channel Monitor Audio soundbar sized for televisions above roughly 60 inches, combining the front left, centre and right speakers in one cabinet.
SB-3 is the middle size in Monitor Audio’s passive soundbar family. It keeps the front of a larger television installation visually simple while still allowing the system to use a normal AV receiver, surrounds and subwoofer.
Installation and System Planning
Screen width and mounting height should guide the choice between SB-2, SB-3 and SB-4. The soundbar should sit close enough to the screen for dialogue and picture to feel connected, with the subwoofer handling the lowest frequencies.

The Audio Experts Take
The SB-3 carries the same passive three-channel idea into larger television installations, making it a better visual and acoustic match once the screen moves beyond the SB-2 size range. It requires an AV receiver or amplifier and works best when the rest of the surround system is planned around it. We can help confirm whether the SB-3 or SB-4 is the better fit for your screen and room.
