Partycast sound

This is more of a general question. So I got 2 rave+ speakers and have partycast them. The question I have is why does one speaker seem louder then the other? Is it because the primary speaker is connected to my device and the other is being casted to? So it gets slightly more quiet? I have placed them on different sides of the room and used both speakers as primary and have found same result. The primary is always louder then the one being cast to.

Your issue is unusual. Normally, the volume on two same speakers with PartyCast pairing equals. In your case, please confirm they are the same firmware version in the Soundcore APP then restore a factory reset by holding the ā€œDā€ button for 10 seconds in the aux mode.
