Bandpass Filter: A filter that has a finite passband, neither of the cutoff frequencies being zero or infinite. The bandpass frequencies are normally associated with frequencies that define the half power points, i.e. The -3 db points. In multi-driver speaker systems, the Midrange driver may be fed by a bandpass filter.
