Pass Filter

What does a low pass filter do to audio signals?

I know what is a low pass filter but it confuses me when it is applied to audio signals.

From what I remember from my electronics lab 10 years before... The LPF simply removes the BASS tones and you will hear more of the Cymbals and Low-frequency tones.

Typically this is used in the Tweeters (to eliminate the BASS interfering the output)

Maybe im totally wrong.. Just what I remember... Im marking this question.. lemme see if this is the correct answer.
