Experience The Unique World Of Surround Sound

From intense action scenes to absorbing dramas, enjoy and bask in the latest cinematic experience that fills every corner of your room with expressive sound. With its precision-crafted speakers and advanced high-quality audio reproduction technology, the sound field created by the SR-B40A envelops you and transports you deeper into the story as it unfolds on screen.

Customise Your Sound With Dedicated Tone Controls

Newly designed tone controls (via Yamaha's dedicated smartphone app) allow you to tweak the sound to your desired state, while still remaining true to the content. The result is an expansive sound field with ideal tonal balance in which every element of the sound shines with stunning clarity, enhancing the unique qualities of any and every entertainment source.


Thrilling, Room-Filling Bass

For a powerful sense of floor-trembling realism right in your own living room, the wireless subwoofer expertly creates the low-end punch and texture you need—putting you right in the heart of the action.

Clear Voice

Yamaha's Clear Voice technology has been improved to make human voices even more audible. Use the Clear Voice feature to hear every word – from YouTube videos to movies and shows, especially when background music and sound effects try to take centre stage.


Four Sound Modes

Four different sound modes are accessible, making it easy to match the sound to the content being played and the desired mood. Standard mode is ideal for TV shows, while Stereo mode is best for music and concert videos. Try Game mode to immerse yourself in your latest battle, and use Movie mode to create an expansive theatre experience.

Bass Extension

Whenever you want more bass, use the Bass Extension feature, for a broader and more muscular presentation. Enjoy content with more power and presence.


Easy To Set Up & Use

HDMI-CEC and eARC compatibility allows you to connect this Sound Bar to your TV with a single cable, and use your TV remote to operate basic functions on the SR-B40A. For even more detailed control, you can conveniently adjust the volume and change sound modes with the included remote or Yamaha's dedicated Sound Bar Remote smartphone app.

True Sound

Yamaha knows sound better than anyone—from the instant it's created to the moment it reaches your ear. By fusing acoustic technology from musical instrument development and electronic technology from professional audio applications, Yamaha delivers True Sound straight to your home or while you're on the go.

Tonal Balance

Every ear hears the world differently. Yamaha expresses sound as the artist intended. Reproducing sonic elements such as vocals, instruments, TV dialogue and sound effects at the right pitch requires both passion and precision. Yamaha accomplishes this through tonal balance, enriching harmonies and recreating musicality to help you hear sounds you couldn't hear before.


Music, at its core, is a connection of one sound to another. They form phrases, with rests added in for alternating expressions of power and delicacy. Yamaha pursues dynamics in sound to contrast the stillness and motion. It's not just the powerful sounds - there's beauty in the breaks.

Sound image

The most loved compositions and performances make you feel like you're there - whether it's the front row of a live concert or the best seat in a theatre. Yamaha approaches spatial expression with nuance and precision, accurately reproducing the sound image to not only convey the position of an instrument or artist, but also the movement behind it.
