I thought the JL audio W7 was a really nice unit, expensive but according to everyone well worth the money.

 

I don't know if I would say its worth the money. It's a decent driver, but not what I would choose. I had one in my FC for a while, but unless I was listening to rap or bass demos, it didn't work that well for me. Doesn't respond as much as I wanted, was rather ineffiencient with the 500/1 powering it. For about the same money, I would get an Orion H2 instead, or even an eclipse titanium, or Focal, but even that is overkill unless you want mad bass
