The PulseAudio PAEXWIR wireless audio extender allows stereo analog signals and subwoofer audio to be extended wirelessly up to 164' (50m) with line of sight or 50' (15m) through walls, ceilings, and floors (WiFi rules apply). This device utilizes 5.2 GHz or 5.8 GHz signals to help reduce interference resulting in a consistent and stable connection without comprising audio quality. The PAEXWIR is a great solution where cabling cannot be run to remote speakers or subwoofers.
