ESX QUANTUM QM-FOUR - 4 channel digital amplifier

QM-FOUR  

The 2-channel mini power amplifier  , which is about the size of the palm of your handQUANTUM QM-TWO  immediately caused a stir among ESX fans and car hi-fi enthusiasts when it was unveiled. The small powerhouse with a whopping 240 watts RMS output was immediately considered an insider tip. After last year's improved V2 version topped that with an incredible 300 W RMS output, ESX is now following up with two more models in the QM class: The powerful QM-FOUR power amplifier is now available for 4-channel applications, and those who want to drive a separate subwoofer can now opt for the new QM-ONE monoblock. Both power bars deliver a whopping 360 watts RMS and are visually perfectly matched. All models feature modern and efficient Class D technology, combined with EPS®, top features, and perfect sound characteristics. The QM-ONE monoblock is not only the perfect visual match for the QM-FOUR. If a separate woofer is to be powered, its area of application is clearly defined. With a full 360 watts RMS at 2 Ω, there is plenty of power.
