A:Answer You could do this, I suppose, if you had a wifi connection to your TV, through which you'd have to pass the audio output signal from the TV through your wifi network to the CC receiver that you'd connect to a speaker through the audio input port on the speaker. There are probably easier and more efficient solutions, especially if you're trying to use it as a home theater speaker. If you have a wifi-enabled TV you could pair it with one CC. I don't think you would get stereo output from one CC because you'd have to split the incoming signal through a Y adapter to the two speakers. Maybe the new CC supports stereo through one audio out jack to a splitter but you'd have to check on this? I don't know. IF you're using it for speakers in other rooms, you'd do better with a Sonos type system than a CC. Sonos and similar systems are designed for spreading music all over the house. You could do this with one CC for one speaker or more than one wired speakers but pairing more than one CC to your wifi and source would be problematic, based on the frequent connection problems I have had with CCs just using them for single speakers.
You're better off using wired speakers as rear speakers for home theater. The latest systems (Samsung does this well) use bluetooth to connect the rear speakers with wires to your subwoofer then to the TV's audio out via the soundbar. This approach makes a CC unnecessary.
One issue to consider is latency. Home theater is finicky about syncing sound out to distant speakers. Investigate before you buy!
