ESX Quantum Qs-Two-Iso

With an impressive 2 x 95 watts RMS at 2 Ω, the little Quantum QS-Two is anything but slim. On the contrary, it drives loudspeaker systems with 4, 3, or 2 Ω impedance without difficulty and remains very stable even under critical loads. With a mono bridge output of 190 watts RMS at 4 Ω, it can also elicit a lot of bass from subwoofers. It impresses with its high-end sound: thanks to the huge bandwidth of up to 60,000 Hz and a sensationally low distortion factor of less than 0.007% (THD + N @ 5W), the QS-Two is way ahead.

ESX masters the construction of Class D power amplifiers so well that the QS-Two can achieve a sensational efficiency of up to 90% and is EMC interference-free. The modern technology saves electricity, relieves the vehicle's electrical system, and protects the high-quality components from overheating. Thanks to the high degree of efficiency, no thick power cables need to be pulled. If you want it to be very easy, you can use the QS-Two-ISO, which can be supplied via a pre-assembled ISO cable harness, for example, to connect behind the car radio.
