It's not that simple...
Dive a little into digital signal processing topic and you'll very quickly realize that's impossible to affect just one part of the frequency range. If you "touch" 50 Hz - you are affecting the whole frequency range. Unfortunately, you can't beat the mathematics - that is true even for the simplest DSP effects like high-pass filter.
Yes, SVS uses DSP - but that is limited only to the lowest frequencies where these artifacts are (almost) inaudible and irrelevant - and it's not affecting the full frequency range / stereo signal which is on completely different signal path. Still, for any e.g. PEQ adjustment on SVS near the crossover frequency you also need to adept the phase - because its filters introduce a phase shift. And the phase is just one part of the story. There are different kind of filters - some of them don't even affect phase, but have other problems / limitations - like pre-ringing.
