'woofer' originates from the English word 'woof,' which is an onomatopoeic representation of a dog's bark, symbolizing the deep, resonant sound produced by the speaker.

'woofer' was derived from the term 'woof' in the mid-20th century to describe speakers that produce low-frequency sounds.

Initially, it referred to the deep sound of a dog's bark, but over time it evolved to describe a type of speaker that produces low-frequency sounds.
