Not a dedicated speaker. It's following on from this idea:
Stackable tech tower. Why do I always have to install another box with another plug when they could all just fit together?
The idea is to create a consumer level tech rack that can live unobtrusively in the home. The base and top would come as a package for power and controls, and then you can stack up modular units for whichever functions you need (router, wifi extender, switch, nas, smart speaker etc.).
Right now I have 4 or 5 different white boxes sitting around as independent units with cables and plugs everywhere, and it would be great if they could all be put together into one unit that I don't have to keep in the dark corner of a room.
