I have a 16*16 screened porch with 15' vaulted ceiling. I want to install wireless outdoor speakers in 2 of the ceiling corners. Sonos are the only ones I've heard - does anyone have any suggestions for alternatives? I'd like the highest quality sound - I'd be streaming music from Pandora or Apple Music. The speakers need to be somewhat weather proof - I already have cool portable bluetooth speakers, want something more permanent. Thanks -
