Do these woofers look right on these Dunlavys IVA's?

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.

Jose, they were good enough for me to keep them for 19 years, way longer than any other component I've owned.  I only sold them because I knew I would be moving plus a very good buyer happened along.
