In addition to the above, if you're not adverse to buying from a manufacturer without a US distributor, you could try Duntech, very similar designs, at least in their Classic series (many of their designs were originally John Dunlavy's while he was there). Also, Dynaudio designs, while not executed the same way even though their driver array would imply that they are (my understanding is they are a line source speaker, rather than a point source like the Dunlavys), can give you that "big" sound that Dunlavys do so well and are excellent speakers.
