Unfortunately, there are still no true 'wireless' speakers. They always have wires of some sort to plug them into the RF module or to power outlets. Even the stuff that is available is not very good (yet). You could get a small for factor speaker like Mirage, Anthony Gallo etc. These could go on very thin stands against the wall and would not be very noticeable. Since they are very small, you could use a small gauge speaker wire and run it along the baseboard.
