I have older Epos M5 and had M16 and they are built like a tank. No problems and fabulous sound. Seems all subs with electronics eventually have issues. It's a matter of when will they act up. Not so much speakers. I am not thrilled with the newer Epos sound. Their newer soft dome domes have an edge that I never experienced with their metal dome. Usually it's the other way around..
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.
