We’ve maintained extensive traceability records describing the elements in every loudspeaker that we’ve made since the 1980s – tens of thousands. They tell us about the drive units and the crossover, who tested them here, about the veneer, cabinet maker, who assembled the system, who acoustically measured it and who finally inspected and sealed the carton. It takes time for sure, but above all, it fosters a culture of personal responsibility here at Harbeth.
