Round speaker with a grille all the way round
Røst is a small active speaker with a 3″ full-range driver in a bass-reflex cabinet and a grille of hexagonal holes all the way round. On top there is a 2.42″ display, five buttons and a gold volume knob. It plays in sync with S1, Node and Touch in other rooms, and you print it on your own 3D printer.

Everything on top
Five buttons at the front, the display behind a clear window flush with the top, and the gold volume knob at the back. The lid has a soft, rounded edge.
Display and favourites
The 2.42″ OLED shows station, track, artist and volume. Four buttons start your radio favourites, and a long press saves the station that is playing.
Grille all the way round
The grille sleeve has Skjold’s hexagon pattern all the way round, with a dark core behind it that gives the grille depth. SKJOLD sits in gold at the bottom of the front.
Connectors at the back, port underneath
12 V and USB-C are at the bottom of the back. The bass port goes down through the base, and the rubber feet give it room to breathe.
Printed and held together by four rods
The core, the grille sleeve, the lid and the base are printed in PETG or PLA on an ordinary 3D printer, without supports. Four M3 threaded rods run from the lid through the core to the base, so no screws are visible. The driver sits on a replaceable plate, so you can switch to another 3″ driver by printing a new plate.
For the living room, kitchen and bedroom
The grille is open all the way round, so Røst does not handle splashes or steam. Put it on a shelf, a table or a bedside table. It runs on safe 12 V from an ordinary adapter.
Integrations with Lyrion, Home Assistant and Homey
Lyrion
Skjold shows up as a player in Lyrion, with radio, favourites, local files and synchronised groups across rooms. Skjold connects to an existing Lyrion server, or can run the server itself.
Home Assistant
Skjold is discovered automatically as a media player with source, volume and on/off. It can be used in automations, for example radio when you get home.
Homey
Skjold appears as its own device with its own icon, and can be controlled in Flows: start a favourite, switch source or turn the volume down.
