Beosound Theatre

Aluminium with Grey Mélange Fabric

A new vision for sound

A soundbar that completely flips the script. Make every movie an unmissable cinematic event.

Four patent-pending acoustic innovations in one sleek soundbar envelop you in sound from every angle. Made to fit any TV, and last for generations.

Beosound Theatre doesn't just lead from the front. Twelve custom drivers direct sound above, below and to the sides of your screen, creating a complete spatial experience that immerses you in the moment. A coaxial centre channel ensures crisp and clear speech, so you won’t miss a word or whisper. Absolute fidelity has come home.


For generations to come

Good things never last? Beosound Theatre proves otherwise. It’s designed to be updated instead of replaced, with software that can evolve over time to bring new features. Time for a bigger screen? Slot a new one in. This modular approach means Beosound Theatre will continue to deliver a spine-tingling cinema experience for years to come.


Timeless quality

Made with materials as beautiful as they are durable, Beosound Theatre proves that good things do last. There's the timeless touch of aluminium, crafted in our fabled Factory 5. And solid oak or fabric covers that you can change over time. This is style and sustainability, united.


Lights up when you're around

Step close to Beosound Theatre, and the minimal interface springs into life. Use the glass touch panel to explore your music, choose your presets, or pair with a Bluetooth device. All this, with just a touch.


Run the show

Beosound Theatre is made to fit seamlessly with your TV, and your room. Colours, materials, position – they adapt to your vision. Want to see it in situ? Our augmented reality app lets you perfect your set up at home, without ever leaving the couch.


A sonic centrepoint

Screen off? Theatre still streams the music you love. Seamlessly connecting with other speakers through Beolink, Chromecast, Spotify Connect and Airplay, it becomes a hub for the sound of your home.


Find your own mood

Through the Bang & Olufsen App, once you register the product, you can choose among different "listening modes" according to what you are listening or watching on tv. Hear every voice, action or music clearly.
