I've been doing a good amount of research on setting up a home system using Bluetooth ceiling and in wall speakers and I'm coming up with some mixed information. Is there such a thing a Bluetooth ceiling/in wall speaker? I understand the need for their to be a power cord but I do not have the luxury of being able to fish audio lines through the walls in my home. Are there companies that make Bluetooth capable speakers at this point in time or does everything still have to be wired?
