How much volume can Sonos Arc/Sub handle?

Hi,

My Xbox has a tendency to play at a much louder volume than my television when there is no headset attached.  Last night, the headset disconnected and the sound played through my Sonos Arc/Sub/One(s) instead - briefly - but it was pretty loud.  It was only a second or two but since I don’t typically blast the speakers, I’m mildly concerned that this could potentially damage the speakers.  Of note, they are working properly and there’s no evidence anything actually happened. 
 

I really would like to know how the speakers are designed and if that 2-3 second volume blast could do anything troublesome. The actual volume was probably 30% max (30) but it was loud.  

Can someone enlighten me? Like, how would I know if one of the eleven internal Arc speakers wasn’t working? 
 

Thanks!
