Blown Mid Driver


Listening to some music yesterday for the first time in 3 months. Didn't sound great. Heard a bit of crackling from the left speaker. Took the grill off to find the 'foam' ring around the mid driver had gone flacid / half of it caved in. Not sure how this could have happened. Tunes always played at a decent volvume, but nothing extreme to cause distortion, no physical abuse, etc. Any thoughts on how/ why this could've happened besides volume? Dynamics of some sort? Age?

Well I knew it was common and easily fixed but that was a long time ago. Now a quick search for speaker surround repair turned up YouTube DIY videos and PartsExpress DIY kits! Crikey! Interweb! Gotta love it!
I'll have to look into that. Might see how that turns out and if it's a fail then.... I had to get replacement tweeters for a friend from Paradigm 2 years ago for same age speakers. They had them in stock but only sold in a pair. Only 75 bucks. Even if they have these drivers still available, or ones that would work, I'm sure they'd be considerably more bucks, esp if sold in a pair.
The foam surrounds shouldn’t cost more than $20 delivered. I replaced the foam on a pair of 6” mids without any drama and there was no voice coil rubbing, just don’t lay them at an angle while the glue is drying and if 1 of them rotted I would expect the rest that have foam surrounds to follow. 
I pulled a pair of paradigm Titans out of closet after 20 years, surrounds where gone. Ordered surround/glue kit, it's cheap. Never done it before, watched sellers how to video. I was surprised how easy of a fix it was. Worked like new.
