Hi - We did this for one sound installation that was quadrophonic and prerecorded . We had two stereo SD card players connected to the same power source. The SD card players would start playing automatically when switched on so the quadrophonic image would work and would be synched automatically - you could use as many as you want I guess so theoretically a 32 speaker image could work like this - but Im not sure if the timing would be precise enough for something like ambisonics unless there was some sort of clock synchronising them more precisely. I also looked at those things that send the audio down the power cables - but if you have a large installation with a couple of different generators running the speakers it doesnt work because they're not all on the same power grid. A lot of the sound installations Im referring need to be tweaked live and even composed in situ so use live streams rather than being prerecorded. I think the best way is possibly the seinheizer headphone boxes with an Ipad/tablet controlling a base station over a 3g connection with something like Iteleport but Im I'd love to hear more about these wireless speakers . If latency isn't too much of an issue (which it isnt for me - I dont mind it Im tweaking the level on one speaker if theres a few ms latency) maybe the channels could be sent over a 3g connection or ad hoc wireless network ,synchronised and with some sort of D/A converter at the speakers....
