Great App

Great App - would love to see a way to group subs together to allow adjusting things like volume just once, instead of having to switch between subs.

Not bad

Was very surprised to see that I can’t control both subs at the same time. This is a must feature in my opinion. Also no mute is a little strange. Hopefully these features will be added very soon considering the price of these subs. Thanks.

Der Wahnsinn! Wen es jetzt noch die Funktion gibt den Sub mit dem Handy auf den Hörplatz einzumessen ist alles Perfekt
