Question

difference between sub woofer and woofer?

Answer 1

A subwoofer (or sub) is a woofer, or a complete loudspeaker, which isdedicated to the reproduction of low-pitched audio frequencies known as bass. ... There are no stark differences between these two speaker systems as both are used to reproduce low-frequency sound notes.

Answer 2

Although there are loudspeaker drivers specially designed for the purpose such as the Eminent Technology Thigpen Rotary Woofer T
or loudspeaker drivers with very long cone excursions such as the JL Audio Fathom f113Apart from the first mentioned all the others are woofers. There are different “types” of woofers, or woofers designed for different purposes.

The only difference is that they are all designed to respond to a given range of frequencies.

A standard woofer produces frequencies between 20 and 2,000 hertz (Hz) its “sound quality” decreases as the speaker approaches either end of its attainable scale. A mid-woofer can reach higher frequencies than a standard woofer, with a maximum range of 5,000 Hz, but it cannot reach quite as low, with a minimum range of about 200 Hz. (All speakers share the same “quality loss” issues as they reach their limits.)

The difference in the subwoofer is that it focuses exclusively on a small frequency range, usually from 20 to 200 Hz. A rotary subwoofer has a completely different mechanism than the other types of speakers; it uses fan blades, rather than a cone and coil, to create increased air pressure. Rotary subwoofers can reach frequencies as low as 5 Hz.

Unlike the higher-frequency speakers, such as the mid range, mid tweeters, tweeters, and super tweeters, a woofer is a speaker that focuses on the low-end of the frequency spectrum. The term "woofer" comes from the “deep sound” a dog can make "woof,woof,".
