    Hello,

    An other example is the setup in a loudspeaker box,
    Lowpass filter for the basses,
    Bandpass filter for the mid range,
    Highpass filter for the treble.
    An other aplication can be a graphic audio equalizer.
    See the link for more in fo on filters.

    Bandpass filters are used in all kinds of instrumentation, as well, in Seismology, Sonar, even medical applications...for example electrocardiograms, EEGs and such. They are also widely used in optics, such as with lasers, LIDARS, etc. Color filtering is actually a bandpass function. Don't limit your thinking to strictly electronics! There are mechanical equivalents of bandpass filters, as well. In fact a quartz crystal is both a mechanical and an electrical device.

    Even your telephone service uses bandpass filters; the audio side is roughly 250Hz-5kHz.
    If you get DSL, technicians install bandpass filters to split the digital and audio signals.
