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!"
Maybe if they would actually release products in the same decade they announce them, Sling wouldn't have to take such dramatic steps to completely piss off their installed base in order to make a couple bucks.
Out of business in two years. Shame.
