The Mavic 2 Enterprise Speaker from DJI is a replacement for the included loudspeaker attachment. This speaker allows you to project audio to those around the drone as you fly it into emergency situations or on job sites. The 10W speaker is capable of playing sound at up to 100 dB. The 100 dB audio intensity has a range of 3.3'. General communication can vary from 66' to 131', but specific distances will vary based on ambient noise.
