I don't know what kaplandeisgn is talking about, but he's not correct about drivers needing to be reconed. I own 4 pairs of Dunlavy speakers; 2 pairs of SC-Vs, a pair of SC-IVs and a pair of SC-IIIs. I also own a SC-II.CC center channel. Out of 51 total drivers, not a single one has any issues.
The IVs and Vs are incredible speakers, and very accurate. If you want the truth, not a colored version of it, then you can't beat them.
John moved to Australia because the government was giving incentives to start businesses there.
Dunlavy Audio Labs was based in Colorado after John moved back to the U.S., and picked up where he left off with the Duntech designs. In one of his interviews he said that the DAL models were far superior to the Duntech models due to his much-improved measuring equipment and his large anechoic chambers. He considered the Duntechs primitive in comparison.
