I've had my A5's for about a year now and in the last couple weeks, they've been popping quite loudly when I turn them off. I emailed customer support and they sent me their generic "will probably solve it" 13 step email. I don't have another audio source right now to check if it's by sound card, but I thought I'd ask here to see if someone else has had the same problem or knows the solution. Is it bad for the speakers? It happens almost every time I turn them off. Usually they've been on for hours, but when tested one time I got them to pop every time I turned them off quickly like 10 times in a row. Thanks for any help. <3 speakers
