Nubert offers a so-called ATM module (Active Tuning Module) specifically tailored to the respective speaker type for all speakers in the delivery program. The ATM module is looped in between the preamplifier and power amplifier of the amplifier chain, or if there is no looping possibility, the ATM module provides corresponding switching options. The module raises the - for physical reasons - decreasing frequency response of the loudspeaker in the lower frequency range in a mirror image before amplification, so that the maximum possible lower cut-off frequency of the loudspeaker is shifted down by - depending on the model - up to an octave. At the same time, the signal is attenuated steeply below the new cut-off frequency, which leads to a mechanical relief of the (bass) loudspeaker and, incidentally, in addition to an electrical relief of the downstream amplifier / power amplifier. Such a "tuned" speaker easily "grows" in terms of hearing to twice its actual volume. As a further feature of the ATM module, the frequency response can be tilted linearly by up to ±7 dB (based on 20 kHz) over the entire frequency range. This results in a very natural frequency response curve of the connected (Nubert ) loudspeakers for certain listening habits (for example, a linear frequency response drop of -3 to -4 dB is typical in a concert hall occupied by listeners). In terms of hearing physiology, a gently decreasing frequency response causes stress- and fatigue-free hearing, even over a longer period of time.

The extension of the bass depth is infinitely variable, as is the frequency response control.
