If you want to use the speakers as rear surround with the beam, then the setup will require the mics to be turned off. Thus you won’t be able to use the mics on the One in that configuration. Also, the speakers will be bonded to the Beam, meaning that they need to be in the same room as the beam to connect wirelessly without issue (using 5.0 Ghz instead of 2.4 Ghz) and therefore, wouldn’t make very good speakers to take outside.
The Move is actually excellent for taking outside, as it has some waterproofing, battery, and can connect by WiFi or Bluetooth if WiFi coverage doesn’t work for outside.
