Epos speakers - no longevity?

I have recently had an Epos M Sub turn into a paperweight and a pair of Epic 5’s start squeaking on lows.  Gently used - low hours - low volumes — Cambridge Audio 840A V2, Cambridge Audio DAC, Cambridge Audio CD.  Jazz/classical.  They are by no means new but I am shocked at two failures on light duty.  Is this common?  Great while they worked - garbage now - look brand new.  Curious if others have had similar experiences.
