The contributions John made to loudspeaker design changed the rules. With the creation of the Duntech Sovereign while John was in Australia, the rest of the loudspeaker world was playing catch up. This page is dedicated to his work, his technical discussions and interviews. Most importantly its about the legacy he left for all of us. A brilliant design philosophy that is still as valid today as it was 30 years ago. Long live 6db crossovers and time alignment. All hail the king.
