WebAllpasses are probably the most underrated filters and can be a lifesaver in automotive sound. Although they do not affect the spectrum, they affect the phase of the processed signal. This can be helpful on midrange and midbass channels to make staging and integration perfect, when delay in just a certain frequency band is needed.
