The AudiosA12 X1 is the first fully cableless loudspeaker for venues and event spaces. It does not require a wireless router or Bluetooth. You can connect up to 16 wireless speakers and synchronize music across all of them. Audios batteries can be exchanged while the speaker is on and playing music. This means you will have no downtime during your event. Audios speakers can reliably connect and stream synchronized audio at a distance of 100 ft.
