Theoretical background:

Woofer:

Woofer is the term commonly used for a loudspeaker driver designed to

produce low frequency sounds, typically from around 40 hertz up to about a kilohertz or higher.

Woofers are generally used to cover the lowest octaves of a loudspeaker's frequency range.

Tweeter:

A tweeter is a special type of loudspeaker that is designed to produce high audio

frequencies, typically from around 2,000 Hz to 20,000 Hz (generally considered

to be the upper limit of human hearing). Specialty tweeters can deliver high frequencies up to 100 kHz.

Low Pass Filter:

A low-pass filter is a filter that passes low-frequency signals and attenuates (reduces

the amplitude of) signals with frequencies higher than the cutoff frequency.

High Pass Filter:

A high-pass filter (HPF) is an electronic filter that passes high frequency signals but attenuates signals with frequencies lower than the cutoff frequency.

Specifications:

bass, midrange, & treble frequencies in octaves

Bass range in Hz

sub bass 31 to 62 (and lower)

mid bass 62 to 125

upper bass 125 to 250

Midrange

lower midrange 250 to 500

mid midrange 500 to 1K

upper midrange 1K to 2K

Treble

lower treble 2K to 4K

mid treble 4K to 8K

upper treble 8K to 16K (and higher)
