Just buy it!!
Crutchfield Customer Review (What's this?)
My system consists of Boston pro60se front stage image dynamics 6 3/4 coax rear fill plus this monster all powered by an alpine pdx-v9. I couldn't be happier with the way the sub blends seamlessly with everything and the sheer brute force when it's wanted. Cleanest system I've had in the last 20 years. If you have the space and the budget just buy it you'll love it.
Pros: Tight accurate with the ability to get obscenely loud when you want it to.
Cons: None at all
