Principal Audio Monitors

The peak performance no compromise platform aimed at achieving optimum reproductive linearity across three ranges in which all models share identical performance characteristics, the only variant being bandwidth and Sound Pressure Level capability. All aspects of creating this series were viewed on merit and without adherence to any current industry practise of formula. This ‘first principle’ design philosophy saw performance and reliability considerations prevail over fashion, meaningless features, aesthetics or convenience. It also realised new techniques and technologies deployed alongside that which is tried and proven.

Universal Series
