Compact sound bar with built-in bass

The Yamaha SR-B20ABL is a single-unit sound bar that integrates two 3-inch subwoofers, delivering 120 W total power without a separate bass module. It suits viewers who want richer TV audio and music streaming in a slim form factor.

HDMI ARC and dual-device Bluetooth

HDMI ARC carries audio from a compatible TV over one cable and enables TV-remote volume control. Two optical inputs connect additional sources. Bluetooth remembers two paired devices so you can switch playback between them without re-pairing.

120 W total output with 60 W dedicated to bass

The amplifier provides 30 W per front channel and 60 W to the built-in subwoofers, fixing the maximum loudness and low-frequency impact. Buyers needing higher output or a separate subwoofer for larger rooms should consider a different system.

Questions about this item

Will the built-in 3-inch subwoofer cones need replacing over time?

The dual 3-inch subwoofer cones are permanently integrated into the sealed cabinet and have no user-replaceable parts, so no scheduled replacement is required.

What limits output during long movie sessions?

The internal amplifiers are rated at 30 watts per front channel and 60 watts for the built-in subwoofer, so sustained peaks above those levels will trigger the protection circuit.

How much heat or noise does the 120-watt system produce when running all day?

The slim enclosure uses passive convection cooling with no fan, so operation stays silent and surface warmth remains low even during extended use.
