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 sell these things, and the only downside (obviously this is a thin TV with 1 HDMI input!) is the viewing angles are poor. However, viewed head-on (apply directly to the forehead!), the picture is excellent.
With the matching mount, it is stupid thin on the wall, and is definitely worth it for some rooms.
