i am looking for info on celestion car audio subwoofers. one is a ad-12-h, the othe ris ad-15. the car audio department went out of business almost 10 years ago, but if you've heard these speakers you know there isn't much, even to this day that compares. i still have some 12's and 15's, some need repair. they had extreme power handling with an incredibly high sensitivity rating. i hope someone can lead me in the right direction, because they are worth fixing.
