ESX QM-ONE Quantum Mono Class D Mini Digital Car Amplifier

ESX Quantum QM-ONE

The approximately palm-sized 2-channel mini power amplifier QUANTUM QM-TWO caused amazement right after the presentation among ESX fans and connoisseurs of the car hifi scene. The small powerhouse with a whopping 240 watts RMS output was immediately traded as an insider tip. After last year’s improved V2 version with incredible 300 W RMS performance topped that again, ESX is now adding two more models in the QUANTUM QM class:

The powerful QM-FOUR power amplifier is now available for 4-channel applications, who want to drive a separate subwoofer, can now use the new monoblock QM-ONE. Both power bars deliver a whopping 360 watts RMS and are visually perfectly matched. Modern and efficient Class D technology is used in all models, combined with EPS®, top features and perfect sound characteristics.

The QM-ONE monoblock is not only visually the perfect play partner to match the QM-FOUR. If a separate woofer is also to be fired, its area of application is clearly defined. With a full 360 watts RMS at 2 Ω, sufficient steam is provided, and the bass level can even be conveniently adjusted using the remote control.
