Is there any PHYSICAL difference between a Woofer & a Sub-woofer? If yes, What is it?

ha! there really is no physical difference to the things besides the fact a subwoofer is usually placed alone not with a midrange and tweeter in the same box. A subwoofer is by itself and all it requires is a signal going into it. it is self powered and it does not rely on the reciever or amplifier, and a woofer on the other hand usually is more useful if you don't want to blow the hell out of the people's eardrums in a concert. but all in all, the difference is the speaker itself, the subwoofer adds more rumble to the sound and the woofer is good for volume.

I just got done eating so this one is eay!!!

I had a Pizza sub and I woofered it downed LOL

actually it produces the punch and the bass drum or a low rock solid bass picture a person playing a bass in the room it can reproduce that very easy.

sub woofer and woofer aer the same ask any pet sroe hahahaha ok (joke there) ask any music store I love powered woofer for the fact that they amp the signal nore then non powered the stereo has to do it and it does not work so good.

sub's give off the deeper sound-the low end sound.

woofer just goes woof woof.
