My situation was some what similar to yours a couple yrs ago. Wifi on my receivers has been not so dependable where as Sonos is almost bulletproof for me. Electronics all in closet close to exterior wall, cables run out to covered deck for tv and speakers. Tv is brought in during Dec-March, otherwise has fabric cover on it. Remote control is rf with blaster in closet for switching between tv, bluray, music, etc. Sonos app on iPhone and IPad for music. Deftech 6500 speakers on deck, compared a lot and these were best value/sound for me. I have OSD rock speakers in a different area and they are very impressive so I imagine their outdoor speakers are as well. Of all the listening areas in my home the outside is most enjoyable as it's so relaxing, hope you enjoy yours.
