Replace Dynaudio woofers?

Here you go- 

@xidnpnlss Phish has an app called Livephish that I accessed through Apple TV, they recently posted two shows from SPAC for their flood relief charity. I have an account but I think these videos are free to access through the app, and downloading the app is also free.

Yep, all original drivers and parts, no service has been performed. I’m not sure the drivers themselves are even serviceable aside from maybe re-foaming a woofer. The way I see it the ferrofluid is there to protect the tweeter, so I’m assuming it hasn’t dried up because the tweeters haven’t blown up and mine have seen some heavy use. There is a big backplate on the tweeter, I never bothered removing it, it looks pretty secure.

The crossover will be able to be removed once the woofer is out.

Ok got one out. Ours are different because mine did not have that thin black strip. Glued all the way. I lifted a bit while my partner made tiny slices in the glue. After three or four, it all started breaking down.

Now the part I had dreaded all along: I don't have any soldering skills. Do I need them to test the driver/crossover? 

I was under the impression that ferrofluid can dry over time and cause damage/distortion in the tweeter. 

Dynaudio drivers cannot be repaired, email Dynaudio and they will put you in touch with the nearest authorized dealer so you can order a new one. You only need to replace the one that damaged and why your add it replace that terrible internal wiring.

Replacing the driver and wiring is easy if you have even a little bit of diy experience . 
Good luck. 

@xidnpnlss Your first challenge will be de-soldering! If you’re not up to investing $200 or so for some decent soldering kit, you might consider taking the crossover to a local tech shop or friend who can undo and redo the joints for you. Of course, you could get by with a 25 Watt iron and a ‘Solderput’ sucker (nothing less, no substitutes).

The component that blew up on the one board was one of those ‘$2.00 resistors’ referred to above, often termed ‘sand resistors’ —they are not expensive. The other commonly replaced items include any electrolytic (‘can’) capacitors, as they dry/wear out after years of service, even if they’re not used. Again, not a terribly expensive part unless you’re going for super high quality. Parts Express can hook you up. Would be a shame to have them fail soon after you get the speakers all reassembled. Original performance will also be restored.

Good job on getting the first woofer out. I approve of your method, for what it’s worth. Good luck with your project, I’m sure you’ll be pleased with the result.
