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!"
Wrong, what we hear is not vibration, but changes in pressure... i.e. you have a SPL meter not a vibration meter.
This sub is fantastic, little or no vibration from the cabinet, lots of SPL. I've installed and listened to lots of in-wall subs, they all tend to get muddy sounding. No one seems to have damped a sub well enough to stop the wall from vibrating....
