I would send that sub back!! They are designed a certain way for a reason, and if someone else messed it up why not. I'd rather wait for a replacement. I would say the accuracy of my JL 12w6, is very nice. But it was 4 times the price of yours. I always bought stuff off of my friends, and wasn't used to new prices, but wanted to get something I was pretty sure would make me smile. Definately not dissapointed. chris
