ESX HXE1200.1Dv2

The ESX HXE1200.1Dv2 from the HORIZON series is a powerful mono Class D amplifier that combines high output power, reliable technology, and versatile adjustment options at an attractive price.

The HORIZON HXE amplifier series serves as the entry point into the world of ESX amplifiers and impresses with high-quality components, meticulous craftsmanship, and robust technical features. The solid aluminum heat sink with acrylic inserts and the recessed diamond-cut logo give the amplifier a premium look.

With an output power of up to 600 watts RMS into 1 ohm, the HXE1200.1Dv2 offers ample power reserves for high-performance subwoofer applications. The efficient Class D circuit design with a MOSFET PWM power supply enables an efficiency of up to 84%.

For custom sound tuning, the system features an adjustable low-pass filter, a subsonic filter, a bass boost, and continuously variable phase control. The included compact bass-level remote control allows you to conveniently adjust the subwoofer level from the driver's seat.

Thanks to its high-level inputs with the ESX Error Protection System (EPS®) and automatic power-on function, the amplifier is also suitable for integration into vehicles with factory-installed audio systems.
