Direct or Capacitor coupled? KH120

[Lilith]

Does anyone know if the Neumann KH120 or active studio monitors in general are direct coupled or capacitor coupled? As far I understand in the latter case DC signals will not pass through to the woofers. I wonder what to take care of when doing sound design.

The presence of an infrasonic filter (high pass filter with a corner frequency of 30 Hz, 6 dB/oct) will mean that it is not DC coupled.

Thanks, but does this mean that DC above 30Hz comes through? What would happen if i send a DC signal of 0dB to my interface? Will this even go to the speakers?

Thanks, but does this mean that DC above 30Hz comes through?

Huh?

Huh?

Got it

So what is written here seems not correct
