Is there a way to create a high-pass with a variable low-cut frequency?
The idea is to create a subwoofer whose low cut-off frequency is raised with the increase of input signal value....
So when listening to music at moderate levels the subwoofer should reproduce frequencies down to e.g. 20 Hz. When the level is increased the cut-off frequency should be continuously raised to .. let's say .. 60 Hz when really loud!
Would that be possible?
Thanks in advance!!
