MB Quart Polaris Off-Road Grade Audio


The 1960’s were an esoteric time in the audio world. Only the most discriminating music enthusiasts could embrace the components of the day, made only of wood and tubes.

Founded during that decade, MB Quart established itself as a key manufacturer of high quality audio components. Throughout five decades and several technology revolutions from the days of ‘wood and tubes’, MB Quart is still the global standard, creating only the finest high performance audio equipment.
