^While I agree, there is added interest in that the mod was done by an ex DAL employee.
In one of my last conversations with John Dunlavy he said he was excited by the potential of going forward with digital active cross-overs and individual Class D driver amplification. He did say that the he still waiting for better chips to work with and that the initial offerings would necessitate high development cost that would have to be passed on to the consumer. On the plus side; once that development occurred that it would eventually and progressively cut down on the labor costs. Remember each speaker that Dunlavy made at that time was made with complex cabinets, selected and sorted parts, and each and every speaker hand tuned to model specs. He expected to be able to eventually offer better products at much lower prices.
