           Summary: Implement highpass filter for small speakers even
                    without subwoofer
           Product: PulseAudio
           Version: unspecified
          Hardware: Other
                OS: All

PulseAudio already has a crossover filter that sends low frequencies (that the
main speakers cannot reproduce) to a subwoofer.

There are at least two people (myself and bryak from linux.org.ru) who want a
similar feature that does the same filtering, but throws low frequencies away
instead of delivering them to a subwoofer. The problem is that small speakers,
when given low-frequency content, not only fail to reproduce it, but also let
it distort mid-range content (i.e. exhibit intermodulation distortions).

This feature is already widely implemented by Canton (a speaker manufacturer)
in their hardware, they call it "Displacement Control".
