The SYMFONISK Wi-Fi book-shelf speaker delivers excellent sound and can be used, thanks to its rectangular shape, as a wall rack when mounted horizontally. It carries a weight of up to 3 kg and may thus serve as shelf for books or decorative items. With its plain design and discreet colours, the speaker blends well with different interiors. It is controlled via the Sonos app, can be grouped together and also supports multiroom mode.
