★★★★☆ - Widescreen sound from a lengthy bar

"The SR-B20A is a stereo soundbar, with six drivers in all. Four of these fire upwards if the unit is benched (forward if on the wall)"

"Despite its slim dimensions, the SR-B20A carries that welcoming full Yamaha tone. It’s close to its smaller sibling in terms of character, only the scale here is predictably greater. The balance is good, too; it is easy for manufacturers to roll off a lot of top-end at this entry-level price point, to avoid anything too harsh, but the SR-B20A is happy to go high into the high frequencies with confidence."

Instant Immersion

3D virtual surround creates a complete sound experience. As soon as you hit play, you’ll hear sound from left, right, back, and even above you. Virtual 3D surround and DTS virtual:X technology come together to envelop your whole body in sound.

"DTS Virtual: X" is a virtual 3D surround mode that reproduces height direction in addition to front/back and left/right. As a result, the sense of unity between the video and audio is improved, and in addition to the front-back and left-right spread, you can feel the sound that surrounds you from above, further improving the immersive feeling in the world of movies and music.

Simple to Set Up, Simple to Use

In just minutes, you can install this soundbar and enjoy an instant upgrade to your sound. Simply place the soundbar under your TV or use the keyhole to mount it on your wall.

Easily adjust sound modes, volume, and more with the Sound Bar Remote App for your mobile device. Plus, an HDMI ARC connection allows you to control your TV and soundbar with just one remote.

Simple one HDMI cable connection supporting audio return channel (ARC) that can transmit TV audio, and be linked with a compatible TV to control power on / off, adjust the volume, switch contents, etc.

Crystal Clarity

Thanks to a built-in dual subwoofer, you’ll experience the full range of bass from a single soundbar.

Dual built-in 75 mm (3 ") subwoofer unit combined with the dual bass reflex port, provides a rich and spacious bass range. The 55 mm woofer units and 25 mm (1") tweeters, further achieve a well-balanced and spacious sound quality combination from low range to high range.

With Yamaha's clear voice function, you can automatically distinguish human voices such as dialogue and narration from other sounds, increasing the volume of only human voices. Even in movies, dramas, news programs, and music where background music and sound effects have been used abundantly, the human voice is clearer and easier to enjoy. BYO Christopher Nolan film!

You can enjoy the sound of movies, music, TV programs and games with Yamaha's optimal sound modes. Select from four options (Stereo, Standard, Movie, Game) designed to suit your content. Stereo mode to match stereo playback of music, Standard mode for most TV programs, Movie mode for movies to enhance space expansion, and Game mode to immerse yourself in gameplay content allowing for individual sound action localization to be clear and precise.

Easy Listening

Pair your soundbar with any Bluetooth® compatible device to stream your favourite music, podcasts, and entertainment.

Fits Right In

No need to make room for anything but one small soundbar. A built-in subwoofer enables this device to stay compact while still delivering powerful bass.

A cleverly designed centre unit carefully compliments the screen even when placed in front of your TV. The keyhole wall mounting design allows for a simple and smooth installation appearance.
