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!"
The acid test for Leon will be sound quality. I believe there is a sizeable market for suppliers of audiophile ON-wall speakers. I hope Leon succeeds. I am surprised that Axiom has not entered the ON-wall market since the have several IN-wall models that sound good.
