@timlub Are these the ones you're referring to? https://www.parts-express.com/HiVi-D6.8B-6-Poly-Bass-Midrange-Shielded-297-444?quantity=1
They look the part. My concern (and please correct me if I'm wrong) is that Dynaudio designed the woofers to work specifically with the tweeter. Wouldn't one run the chance of throwing off the speaker's sound with a driver that is not OEM?
But that may not be a concern after all...
So after trying and failing to remove the woofer with a plaster knife, I approached it from the rear, thinking I could push the woofer out from behind. The wire connector came off more easily, but it had definitely been glued. As I was removing the foam, this appeared:
(I'm not sure the picture is showing up, so I'll described it as a corner of the foam covering the crossover as burnt)
Lo and behold the component looks fried
So maybe I can assume the problem is actually the crossover? It doesn't look good, either way. Do I replace only the component or the entire crossover?
I still need to figure out how to remove the drivers to be sure; plus I obviously need to get the crossover out through the woofer hole. And I want to change the Ferrofluid while I'm at it. I tried pushing it out from behind but it still won't budge: considering the speaker connector was glued, I can only assume it's glued (maybe they didn't glue it on the mkII...I'll contact Dynaudio). Any advice on removing a glued driver? I am honestly stuck ;)
Thank you all again for your help in this journey. For reasons I won't get into, it's been a therapeutic process giving these some TLC after all this time.
