Ramilio, these were Duntech, not DAL models.
If you don't receive info from an owner here, you have two other options. Contact Duntech in Australia, although someone else posted disappointment from their contact saying no information forthcoming, only advice to buy new speakers. Company changed hands again about a year ago from those who took over when John Dunlavy returned to the US and started DAL.
Also, do a search here and on Speaker Asylum. Someone else ask about the PCL-15 a couple of years ago.
Good luck.
