They do take some time.....need alot of power too...What kind of amp do you have....My best friend has the 802's so Im familar with them. I own Legacy Signature III's ...bought them brand new...when I first got them, I was like man these really can't sound this bad can they...Called Legacy...asked for an extension on the demo period...then about a week later it was like a light switch was flipped ..it was like WOW.....Cant explain it, but hang in there !
