@malte Looks like a nice product and the #reparability is a huge plus. It doesn't look like it has anything to do with being open source, though. At least I can't find any information that claims the hardware and/or software design to be open source.

On the other hand there is the Teufel Mynd speaker, that has all design data freely available which combined with a #cradletocradle concept is a huge step forward that other manufacturers should follow.
