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've got a lifetime subscription, but I wouldn't say I was "really feeling the burn right about now" - IIRC the break-even compared to monthly payments was about 2 years, so that paid for itself long ago.
