Well another quality product from focal.

They are incredible, easily the best subs I've ever owned. They sound outstanding, and produce intense amounts of bass. If you want clean clear bass they produce that. If you want big booming bass they can produce that as well yet still maintain complete control.

As of now maybe three hours of listening time not enough for me to form an opinion , but sounds pretty good. Update this subwoofer is phenomenal for a ten inch, absolutely love my new kx27 elite!!!!
