I have an OLD speaker i found (JL audio) 10".  It has no writing on it.  I hooked it up to a CD player i have with some speaker wire and held it over a bucket, it sounds pretty good, maybe a little dull but that could easily be the bucket.  My question is... How do i know if it is a subwoofer, or just a speaker?  or is there even a difference.  I offered it to a friend to use as a sub in her truck (she has an amp of her own) will this work, or should i just scrap it?

subs in the bucket...sounds like a country song.

take a couple of pictures and we might be able to spot a thing or two that will help answer your question.

Listen. It's All Good.

the dust cap looks a little rough, but that cover does what it says (keeps dust out of the coil).

looks like a medium throw subwoofer, probably 10mm xmax ballpark i'm just total guessing.

if you have a multi-meter and can check the resistance that might give a clue as to the status of the voice coil. otherwise, i don't see any reason not to fire it up. most car subs were designed to work in smallish enclosures and sealed is much more forgiving than ported, so...

maybe a 1.0-2.0 cubic foot sealed enclosure and see how it goes? probably a 100-200 watt amp would be safe and fine. i don't know...something like that probably isn't too far off the mark.

also, i don't think that is the real jl audio, but i'm not sure. their current logo seems to have been in use for at least 15 years.

if it reads something way off, it could have a damaged coil.

btw, you can get a half decent new 12" subwoofer for $65 to your door.
