The Speakers won't be wireless as you probably want them to be powered. But it should be easy with bluetooth 4.0 or Wi-Fi direct to create a solution.
Normal Wi-Fi could be used. The low cost esp8266 makes this possible in a diy setup... Stream a 4 channel audiostream to the 4 speakers. Have a switch on each speaker to select which channel it will playback. Could possibly be solved by streaming 2 stereo channels on 2 different ip ports over WiFi instead. đ Bo-Erik Den tis 28 maj 2019 09:50Augustine Leudar <augustineleu...@gmail.com> skrev: > wow : > > https://youtu.be/KrVGTqRftKY > > Problem is as most engineers know the result of room reflections is > generally comb filtering not increased spatialisation.
