I would like to set up a wireless audio set up for my home, i have 3 room in which i would like to have speakers so i could listen to music. I would like these speakers to be able to connect wirelessly to my pc and android phone. I will have power to supply the speakers. All i could find are some bluetooth systems that could support a maximum of 2 speakers. But on one hand i need three and on the other hand my apartments walls are reinforced concrete so i don't think bluetooth is the way to go.
