I use Roon via AirPlay for whole house stereo (1st floor & 2nd floor) as follows:
RIVA Festival in Family Room
RIVA Arena in my Home Office
RIVA Arena in Kitchen
RIVA Arena in Living Room
RIVA Arena in Dining Room
RIVA Arena in Master Bedroom Sitting Room
RIVA Arena in Guest Bedroom
I want to add additional AirPlay speakers to the mix. Two in the backyard and one in the garage.
I want to mount powered backyard speakers on my house, and they need to be weatherproof. Ideally, each speaker would play in stereo mode. As a side note, I have a Marantz 7.2 AVR receiver in my family room and could use Zone 2 to passive speakers, but I didn’t want to run/route wires through walls and I’m not sure if the same music played over WiFi would be in sync with music played over speaker wire.
I want a portable garage speaker that comes with an internal battery or external battery pack so I can take it with me. A Sonos speaker would work fine, provided I can group it with the Riva speakers. As a side note, Riva is no longer in business. Four or five years ago, I compared Riva and Sonos speakers. Riva sounded noticeably better, has more connection options, and an optional battery pack. They have worked out very well for me.
I’ve done a bit of research on powered AirPlay outdoor speakers and there’s not a lot to choose from. Any advice on any of this would be greatly appreciated.
