Sound Express is the official USA distributor for ESX Audio


ESX Audio, located in Kronau Germany, is one of very few, high-quality amplifier manufactures left within the car electronics industry. The newly developed ESX QUANTUM QE  DSP series is in a class of its own. High-quality components such as low ESR capacitors, shielded inductors, overbuilt power supplies, and versatile crossovers guarantee an audiophile sound experience. Conventional high power class D amplifiers usually cause interferences within the vehicle and can even disturb the radio reception. During the development period, special attention was paid to achieve an emission-free music playback. Visually, the new flagships amplifiers are based on the previously established QUANTUM QE DSP line thus enabling versatile combinations. They are featured packed: 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 the housing. The QE DSP line features an 8 channel DSP with 32 bit/192kHz playback, 31 parametric band equalizer, and up to 48db/oct slope crossover selection. All of ESX Audio's innovations have awarded them the prestigious and coveted EISA Award in the category “IN-CAR AMPLIFIER” as “Best Product 2019-2020”.
