Replace Dynaudio woofers?

I've got the same speakers, and depending upon condition they are probably worth between $500-900 in the used market fully functioning.  It's worth calling Dynaudio or looking for aftermarket replacements depending upon cost since its an easy DIY.

I just popped mine off and it is indeed a D-260 tweeter and looks exactly like that picture. There was no glue holding it in place so perhaps yours is stuck from age or heat (which may explain why it seems damaged). The wires have a bit of solder on them, but this still seems like an easy DIY. Try the other tweeter and see if its also stuck. 

Out of curiosity I tried to pop off the tweeters on my 1.8mk2's and they are stuck on.  I'd try to pry at the edges of the metal ring with a thin flat head to create some seperation, and/or apply some pressure to the back of the tweeter through the bass port using the handle end of a long screwdriver or something.  The tweeters are already damaged so you dont really have anything to lose at this point. Good luck 

I think the Contour series uses a different tweeter, but it should look similar to this D-260 with two metal tabs to connect the wires and then mounting the tweeter into the enclosure with the existing screws. Pretty much plug and play.  Give Dynaudio a call for specifics. 

Ok popped off a woofer and it was as easy as the tweeter so at some point they probably glued as well as screwed them in place, but mine were definitely not glued. The model number on the woofer was 84310 or 15W38 not sure which is the model.

Btw- if it’s looking like a project there is someone on USAudiomart selling a pair of Special 40’s for $1600.  If I didn’t already have 3 pairs of Dynaudios I’d hop on them in a second.  That’s a big upgrade from the 1.1’s and an insane value. 

@audioman58 makes a good point, if there isn't any sound coming from the woofers it could be a crossover issue which would be far less expensive to repair then a driver replacement.  The OEM drivers are pricey, they are built to last so it wouldnt surprise me at all if it was the crossover.  Mine looked new, even the rubber surrounds show very little signs of age. 

That's not true, you can build a really good crossover for less then $100 in parts, the same way you can build quality speaker cables using 12 ga oxygen free copper for well under $100. Dynaudio has upped its game recently when it comes to name brand components in the crossovers, but even the older stuff was still high quality despite lacking some name pedigree.  The sound quality is in the design and execution of the crossover.  As long as the parts do what they are specced to do, it will sound good. 

Wow it looks like a short occurred on the crossover, is the other one like that as well? Best case scenario would be the crossovers sacrificed themselves and protected the drivers. Definitely get both crossovers out and give them a good inspection. You might be able to buy replacement crossovers from Dynaudio or even rebuild them better then new using modern parts with the same specs assuming you know how to solder. If that’s the case and it turns out the drivers are still good, this could be a rather inexpensive repair/potential upgrade.  PS. Mine are also Cherry. Love them, there’s something about the older Contour series.  Solid bass, and strong midrange.  They lack the detail of the modern Dyn models, but are almost agnostic to bad recordings.  

I’d try a hair dryer and a small putty knife. Slowly work the putty knife along the edges while applying heat to loosen the glue.  The lip isn’t wide so you won’t need to go deep with the knife to see results.  It’s strange, my 1.1’s had no glue and both drivers came off freely with the screws removed.  The 1.8’s are definitely stuck on with something besides screws. I bought them separately, years apart.  
The 1.8s have been used daily for over 20 years (H/T setup) and still sound the same to me.  I had a recent Phish concert on last night and really pushed them, mid 90db peaks at my listening position.  The old Danes took it like a champ.  Btw- I added Lytmi led strip on the back of my TV and it really adds to the realism of concert video. 

@xidnpnlss  I’m vicariously following the repair with you and looking forward to future updates. Would it help if I took a pic of the area with the woofer removed so you see the underside?  Good luck!  

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.

It looks like Dynaudio is using standard 12ga copper wire. There’s nothing wrong with that choice, it does the job, especially considering you are talking about runs less then a foot. I’d cut the ends, strip back some fresh wire and reuse it after you have gotten the crossovers repaired. See if there are any speaker repair shops near you, they can fix the crossovers. Or give GR Research a call (1-940-592-3400) they could probably make replacement crossovers as well. The cost to repair can vary greatly depending upon the level of parts used so stick to a budget and don’t let them talk you into high end stuff. I’d keep the budget under $200 for the pair that way you have some budget leftover to replace the drivers. Assuming the cabinets are in good shape I’d peg their value at around $600-700 w/ fresh crossovers, and $900-1000 with fresh crossovers and new oem drivers.

@xidnpnlss any updates?  I’m really hoping you can resurrect your speakers.
