I’m not sure about that! On the other hand, one of the added benefits of Sonos is that they’ll create their own mesh network separate from your wifi network, so it won’t really matter what your wifi is like 
In my case I’d like to expand my in house system with an outdoor one.
A PC with Roon client is using Roon Core installed on NAS. That PC is connected to Technics SU-G700 via USB.
Now, if I wanted to connect to outdoor speaker, which speaker would fit the bill so I would be able to group the two in one Zone. In other words, whatever is played in the house should be playing on the Deck outdoors. Money is usually not a problem, but would top it around $2000-3000.
Thanks and cheers!!!
