subwoofers are stereo bass producing speakers that takes 2 positive inputs and a negative input...dual coil.. there frequence range is lower then to normal woofer, also, subwoofer are specified,not to produce anysound above there limitations, so u cannt usually listen voices or any type of music from them.

woofer are ist of all mono.. 1 positive & negative input... single coil... can produce frequency out of there limited range....

i have had a long relation with audio systems since i was in 10 standerd,
i have made alot of speaker myself.... buying the skeleton and putting on the coils,daiphrame,spiders etc in them , adjusting the frequency level by coil position....
