ESX QE1000.1

The award-winning ESX QUANTUM QE series impresses with powerful digital technology, high-quality craftsmanship, and exceptionally low-noise signal processing. While conventional high-performance digital amplifiers can sometimes interfere with radio reception in the vehicle, special emphasis was placed on reducing electromagnetic interference during the development of the QUANTUM QE models.

The ESX QE1000.1 combines modern Class D technology with carefully selected, audiophile-tuned components. As a result, this mono amplifier delivers powerful and precise bass reproduction with an efficiency of up to 92%.

The QE1000.1 also leaves little to be desired in terms of features. Variable frequency filters, adjustable bass boost, and phase control allow for customization to the subwoofer system. High-level inputs with EPS® (Error Protection System), an automatic power-on function, and start-stop compatibility make it easy to integrate into modern vehicles.

The solid aluminum heat sink with heavy cast aluminum side panels ensures a high-quality appearance and effective heat dissipation. Screw-terminated RCA connectors and the included compact bass level remote control round out the features. The remote control can be installed in a space-saving manner, with or without its housing.
