STROMTANK S-2500 Quantum MKII
Can you call it “the new middle class”? In a way, yes, but only if you orientate yourself within our device hierarchy. Otherwise, the S2500-Quantum is of course absolutely top class. In this model, too, we have implemented everything in line with our uncompromising approach. The so-called high performance balancer provides this unique charging control, ensuring both ideal battery performance and battery life at all times.

For those who do not want to commit themselves in their choice of music and do not operate excessively large power amplifiers, the S2500-Quantum is exactly the right thing. By the way, the S2500-Quantum is the first StromTank in the model range with 16 LFP batteries (48V System), especially noticeable by a greater thrust in the lower mids and a more extended low frequency.
Alternatively, the S2500-Quantum can be used to power a still quite small stereo system. One where an S1000-SourcePower would normally suffice. Which then takes care of all power upgrade thoughts for a long time to come.
