What is the different between subwoofer and woofer??? anyone know what is the different???

do u know bass and sub bass?

Generally you can break down speakers into Subwoofers (sub bass), woofers (bass and mid), tweeters (mid and treble).

Difference between woofers and sub woofers is the frequency range they cover. Sub woofers reproduce sub-bass sounds which is generally everything below 100Hz. This is sound you can "feel" rather than hear. Woofers handle higher frequency ranges in the bass/mid category so things like bass guitars, punchy drum beats etc.

there are mid-ranges too.... which mostly covers the vocal part...
