Tracker system? You mean Polks? Their stuff is all original. Someone makes their stuff, but it's all their design. I've not seen a case like theirs, other than theirs.
Yes, I've heard of cliffstar. In fact, I believe there is (or used to be) a factory in Paris, TX. They had their sign on the outside of the same building as ocean spray--or used to, anyway. It's been a while since I lived over that way.
