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 would suspect that Mits in at the bottom due to being one of the largest producers of rear projection sets. No matter how many times a sales person tells you that the bulb will have to be replaced after X number of hours, customers are still upset when that time comes! I'm surprised that Vizio ranked so high, but I believe it may be a result of same phenomenon as I mentioned above about the Mits. I think that when a sales person sells a customer a Vizio they set their expectations low, and therefor when a problem happens the customer is not all that surprised, after all, you get what you pay for!
