ESX QUANTUM Digital 2CH AMP QM-TWOv3
Amplifier
Why choose this product?
The extremely compact QUANTUM QM-TWO power amplifier has long been one of the top sellers in the ESX amplifier portfolio. Since the larger QM and QL models are now available in black and enthusiastic ESX Quantum fans want to install the small QM-TWO in the same look, we are now presenting the new QM-TWOv3 as an exclusive "Black Edition". The reasons for its success are literally "obvious": At just 7.5 x 12 cm, this small Class D power amplifier is an incredibly powerful powerhouse in miniature format, ideal for driving many speakers up to 2 Ω.
With 2 x 150 watts RMS at 2 Ω, the V3 can easily drive almost any speaker. Compared to the v1 version, the power has been increased by an impressive 25% with the same size. With a bridge power of 300 watts RMS, the power amplifier is even able to properly supply subwoofers.
Despite the 25% increase in performance and the unchanged heat sink, the QM-TWO v3 achieves a sensational efficiency of 85%. This not only keEPS® power consumption low, but also saves you from having to use excessively thick power cables.
The QM-TWOv3 is very well equipped. The often required high-level inputs with plug-in mini-molex connectors and automatic switch-on are equipped with proven EPS® technology. This makes it possible to integrate the QM-TWOv3 into modern vehicles with factory systems and loudspeaker diagnostic systems without errors occurring in the on-board electronics. In addition, ESX does not do without classic cinch inputs: The QM-TWOv3 can also be connected directly behind DSPs or high-end radios at any time.
