Let the hive mind of Engadget get that for you.
"What is the best wireless surround sound speaker solution? I have a home theater where running wires is just not feasible. I have my own speakers, so I don't want a system that has speakers with integrated wireless. I've done a far amount of research and have only come across a few companies that even offer a reasonable solution: KEF, Kenwood and Rocketfish. Is there anything else out there? What do you recommend? Thank you!"
I'm interested. Not going to run out and buy one just yet, but I'm intrigued. Sounds like an extremely easy setup! That alone will score points. I've yet to be disappointed w/ anything Apple I've ever bought.
