Bang & Olufsen Beosound A9 5th Gen Active Network Design Speaker



Powerful, minimalist speaker

Sound and shape unite in this iconic, customisable speaker. Seven drivers bring the power. A century of craft brings the form.

Sculptural design

Beosound A9's iconic shape is designed to be displayed. From afar, it's a minimal masterpiece. Up close, the details shine. Just like your favourite furniture, it stands apart in any room. And if you prefer it on the wall, it rises to the occasion. Enjoy beauty from every angle, whether you press play or not.

New degrees of detail

A9 stands strong on real oak legs, and delivers your music through acoustically calibrated covers. Ringed with precision-milled aluminium and backed by high-quality polymers, it forms an endless loop of engineering and art.

Customisable design

The shape is timeless, but the shade is yours to choose. A9 is a customisable centrepiece that adapts to your taste and space. Want a striking colour? You're covered. Different legs? Swap them out. Personalise your speaker to chime with any room, and sing in any home.

Stunning sound. All round.

Behind Beosound A9's effortless exterior lies an intricate world of power. Seven custom-built drivers deliver exceptional detail. Clear vocals, crisp instrumentation, deep bass – and enough volume to fill any room. It's as rich as it is rounded.

Active room compensation

A9 works out where it is in the room to give you perfect playback, every time. Ensuring bass, mids and highs are never too overpowering or weak. Wherever you place it, it gives a standout performance. No muddiness. No fuzziness. Just pure, clean sound. As the artist intended.

Room-filling sound

When A9 plays, the whole room takes notice. Boasting volume that rivals much bigger speaker setups, it's perfect for large spaces and get-togethers. Want a more immersive experience? Seamlessly connect A9 with other speakers to let the music flow through your home.

Sound mode? Set.

Time to entertain? Dial up the bass. A moment to relax? Level things out, like when it's time for your favourite podcast. The B&O app gives you customisable sound, right in the palm of your hand.

Seamless streaming

Bring all your speakers into the circle with seamless connectivity and intuitive streaming. Your favourite tracks, in your favourite spaces.
