I need a wireless outdoor speaker that will be 400 ft from the sorce.
What kind should I look into? It will be for a horse show on Nov.27. So I need them ASAP.
I would suggest trying the Bose 2.4 Wireless speakrs. I can't vouch for 400 ft, but I have them in a seperate room that is about 100 ft and three walls from the main transmitter and they work great.
