I'm trying to find the best and most economical way have music on our back patio. We have a wireless network and I would love to be able to setup a playlist on one of our computers and somehow transmit it outside. I've been searching online, but have come up empty. I guess I really have no idea what I'm looking for. I'm assuming the speakers, be them wired or wireless, need to have some sort of dedicated transmitter that is the "go between" from your source (computer, receiver, etc.) and the outdoor speakers. Any suggestions?
