Replace Dynaudio woofers?


Hello. I have a pair of woofer blown Dynaudio Contour 1.1s They have been sitting, unused, in a clean, temp controlled room for at least 15 years. I hooked them up recently and the tweeters were emitting sound.

Is it worth to source OEM woofers to replace? Is it an easy job I can manage myself? Any advice would be appreciated. Thank you in advance.

@perkadin Yes! That would be super helpful. I'll go to the hardware store to find a proper putty knife in a bit. I'll keep updating this thread.

God. Phish. That brings me back. I followed them in 2000; seen a total of 21 shows. These speakers have definitely played their fair number live tapes. Which show? My taste has changed a bit since then lol. And I take it you haven't changed the ferrofluid? Maybe I needn't worry about it then. I'd like not to have to pry off another driver.

If the crossover doesn't come out from the woofer hole, and I can't repair it on the inside, then I think it's over: I do not want to have to cut into these cabinets...

Or maybe idk. This whole process has really demystified the internals of a speaker. And I was looking through parts and they're so inexpensive. Maybe I'll get into the DIY game?  

Thanks for your support. Until the next step! - Michael

@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.
