Hard to justify, since the Sonos Sub or Sub Mini are not designed to be moved in the same way as the Sonos Move. Would work probably well when the Move was connected to your internal wifi, but throw a bunch of errors when you were outside of your home, and on a Bluetooth connection. 

Yep but i have wifi vs 6 and it covers my whole yard , i had last year used my sonos one for outside but decided to buy 2 sonos move for outdoors, on wifi , so it should work … would be great if sonos would allow that , I would buy another sub just for that ;-)
