Took my a2 speakers to Nepal, they got played 20 hours a day by random mp3 players, possibly some outputting clipped signal running full volume on the mp3/speakers, this was an outdoor setting. On the last day of the trip they gave up, one of the cones has a tear.
Luckily audio engine has a great customer service, bajaao is replacing them.
These speakers are not like Logitech speakers which I've seen don't sound half as good but can sure take some abuse.
I'm facing the exact same issue with torn woofer lining. What did you do about it??
I had purchased them in the US 4 years ago. I contacted audioengine and they redirected me to re-seller pristine-note mumbai, who flatly refused any service.
