The newly developed ESX QUANTUM QE series is a class of its own. Conventional high power digital amplifiers usually cause interferences in the vehicle and disturb the radio reception. Not so with the new QE models: During the development period, special attention was paid to achieve an emission-free music playback. Also the sound is perfect,  because high-quality components guarantee an audiophile sound experience at its best. Visually, the new five flagships are based on the previously established QUANTUM QE DSP amps with integrated DSP and thus to that they enable versatile combinations. The features are also impressive: Auto Turn-On, EPS, variable crossover filters – everything your heart desires is on board. High-quality connectors and screwed RCA sockets complete the perfect appearance. All amplifiers are delivered with a sophisticated level remote control, which can be installed very space-saving with or without housing.
