Great Sub But...

I've had this sub for a couple years and it's been pretty decent. I'm only giving 3 stars because I blew the speaker not long after I purchased it. I run my PA gear pretty hard and had this one at a club gig for extra bass and it blew one night. Pretty sure I was clipping it for a while, however, I do expect the protection circuit to do something besides just flash a red light on the back of the speaker where no one can see it. Since I blew the speaker, I've replaced it with a Pyle-Pro PDW188 18'' 2000 Watt Professional 8 OHM Replacement Subwoofer. This replacement speaker dropped right in and was simple to install. Since I installed the replacement speaker, I've run this sub at the same levels continuously that caused the other to blow and haven't had a single problem. So I'd say that the original cone is a week point of this speaker but with the replacement, mine's been trouble free and it hits very hard.
