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.
