All that I am seeing on the driver cones is what is called doping. There is nothing wrong with the cone. The surrounds, is that what you are referring to? Hard to tell by the pics.
Do these woofers look right on these Dunlavys IVA's?
Looking at getting these speakers but in the close up showing the woofers they look very frayed- should they look this way or are they on their way out- thks for the advice- here is the link on audiogon-

Here’s a link to images of many IV & IVAs. I don’t see any doped woofers. Dunlavey could have started using them towards the end of production, however. Also, these may be replacements. https://www.bing.com/images/search?q=dunlavy+sc+iv+speakers&id=492B42DFED1B9507AC188862B69C4A4C5... |
https://www.madisoundspeakerstore.com/approx-8-woofers/scanspeak-classic-21w/8555-00-8-woofer/?gclid... Nothing at all wrong with them! I missed a pair an hour away from me for $800. They sold in 8 hours... I just couldn’t figure out a way to get them home, or in my listening room. They’re quite impressive speakers. I don’t think you’ll be disappointed with them! |
Yep, look fine. Fritz uses a current version of them. http://www.fritzspeakers.com/index.asp The random, non factory look of them actually contributes to reducing resonance modes that occur in the cone itself. |
Dunlavy on the model 4s had 3 different versions. The big changes were changing the woofers from Morel to Seas to Scanspeak. The Scanspeak required changes to the crossover and probably to the damping to maintain the Q that John preferred. Along the way Dunlavy sent me 2 new sets of midranges that looked identical but sounded slightly better to my ear. Tom |
I believe Tom may have this correct. I owned a pair of Duntech Princesses which were the older sibling to the DAL IV/IVA. Mine came with Scanspeak woofers but when the DALs were introduced they did not. I assumed John changed to a less expensive drivers. If he did change back to Scanspeak woofers near the end of their production then I expect those may offer somewhat better bass. If you are close enough to pick these up then an audition should put your mind at ease. I think all of Dunlavy's designs were very good if not exceptional. |
