I'm looking into subs on craigslist and i found a 12w7 for a decent price. if i put a dmm on it, is there a way i could tell if it's in perfect condition (more assurance than just pushing on the cone)??

you can check the resistance to make sure the voice coils is good. But I would have him hook it up to make sure it works fine first.
