SGR Audio was born out of a love of music and a fascination with its purest possible reproduction, free from extraneous noise and distortion. Thus, the original goal was to transcend the technical limitations of the day in order to create market-leading loudspeakers for the most discerning listeners. The owner, Stuart Graeme Ralston began experimenting with speaker designs over 16 years ago, trialling many variants of cabinetry, drivers, crossover networks, and aesthetics in pursuit of the perfect loudspeaker. Today, SGR Audio is a prominent manufacturer of high-end audio equipment with a state-of-the-art R&D and manufacturing facility based in Melbourne, and a global distribution network which covers markets in Australia, New Zealand, North America, and Asia.
