I don't recall seeing any wireless speakers in the home theater section other then with sets, but what you will often find setup is the Rocketfish Universal wireless rear speaker kit connected to a system, or pair of speakers. Saves on running cables to rear speakers, but you must provide your own speakers, be it from a surround sound system, or any speakers. Though it says it is for rear speakers, they can be used to power just about any stereo speakers the same way.
