QM-ONE Amplifier

Since its launch, the palm-sized QUANTUM QM-TWO 2-channel mini power amplifier has impressed ESX fans and car audio connoisseurs alike. This small powerhouse, with an impressive 240 watts RMS, was immediately hailed as an insider product. After the improved V2 version surpassed this level again last year with an incredible 300 W RMS, ESX now offers two new models in the QM category: the powerful QM-FOUR power amplifier is now available for 4-channel applications, and those wishing to drive a separate subwoofer can now turn to the new QM-ONE mono block. Both power blocks deliver an impressive 360 watts RMS and are visually perfectly coordinated. All models use modern, high-performance Class-D technology, combined with EPS® , high-end features and perfect sonic characteristics. The QM-ONE mono block is not only the ideal partner for the QM-FOUR, but also, if a separate subwoofer is also required, its use is clearly defined. With an impressive 360 watts RMS at 2 Ω, it delivers plenty of power and the bass level can even be easily adjusted via the remote control.
