This last round of bricking was to bring about a faster CPU in the speakers, as if that matters. Didn't add features, just faster CPU.
Their support is pretty atrocious. They will always blame your router for not handling "point to point internal networking" correctly, as if that's a real possibility. They tell you you have to make one of their speakers your router and your current router needs to be put in AP mode.
Honestly they probably needed the faster CPU because they expect any of their speakers to be used a routers.
