You won't necessarily find a lot due to potential lag issues and sound quality so most companies don't want to risk it only for their name to be dragged through the mud. Some companies like Kef and SVS have wireless mains but the only reputable company doing full wireless is most likely Sonos as that's their main focus. If it was me, I would give Sonos a try because if anyone has their wireless game together it would be them. Now if Sonos sucks I doubt anyone else can do it better.
