Low Pass Filter
In conjunction with high pass filters, low pass
filters are utilized to set up crossovers in multi-way
loudspeaker and subwoofer systems. For example,
in a 3-way stereo system, use the high and low pass
filters on the output feeding the mid-range transducer
to define the range of frequencies it will reproduce.

to the low and high frequency transducers, you may
divide the frequency spectrum so each transducer is
reproducing the range for which it is best suited,
making the system sound its best and operate most
efficiently.
