B&O-Bang & Olufsen Beosound Theatre

Four patent-pending acoustic innovations in one sleek soundbar. With its Dolby Atmos surround sound, twelve custom drivers and versatile TV fit, this soundbar will last for generations. The swappable covers and variety in position means it’ll evolve with your style for just as long.

Eyes front. Ears everywhere.

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 room-filling soundscape that immerses you in the moment. Dolby Atmos allows for true surround sound experiences, and a coaxial centre channel ensures crisp and clear speech. You won’t miss a word or whisper.

Evolves over time

Beosound Theatre is made to move with the times, with advanced software that allows for future features. Time for a bigger screen? Simply slot a new one in. This modular approach means Beosound Theatre will continue to deliver a spine-tingling experience for years to come.

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.

Timeless quality

Not assembled. Crafted. Aluminium, milled and shaped by hand at our own Factory 5. Covers in solid oak or fabric, ready to change as your taste does.

It’s your soundstage. Build it.
