We design and produce audio speakers that have three main characteristics : - We produce them in our fablab and sell them as kits that people can easily assemble. - We published the design plan on internet with and open-hardware license (Creative Commons with Attribution) to create a community around the project. - We use common parts that people can find by themselves so that they can repair it and have a long lasting object. Our first model is a powerful nomad speaker that works on battery. It is meant to be used at home as well as being brought out to friends place or outdoor parties.
