The problem is getting the power to the speakers. Power over Ethernet is
not up to delivering the amount of energy required, so each speaker would
require a discrete [mains] PSU - not very elegant.


The only way to do it would be to place a battery pack in or behind each
speaker, and use the PoE to trickle charge the thing between uses.

Or solar panels?


Also not all that elegant, but it would work, considering that most
folks would not tax the battery pack too much, so the PoE might work.
Still a pretty stupid idea. Wireless power to charge the battery would
be better/more elegant. More radio wave bouncing around as well.

Unfortunately it would also cook the listeners...

Audiofile: - My new wireless stereo has seven by one hundred watt channels.
Cynic: - why my microwave oven is 700W too, but it only goes "ting!".
