L360 and LL3 High Pass Filter

We use L360 and LL3 limiters a lot.
Using a limiter, by definition, generated sub harmonic crud. I f you have a squared off waveform, you will have DC components in the waveform.
We have tried many times to find a way to follow the limiter, with a HPF only to find that the resonance of the filter increases the level to above the level set by the limiter.
Is there any way a linear phase sub 20Hz filter be applied so that the crud is removed but the level set in the threshold is delivered? LL3 is the the same.
