Smooth, perfect bass.
Crutchfield Customer Review (What's this?)
I love this sub. I moved from two JL w1 10" at 700 Watts @ 4 ohms to this focal, wired in series for ~450 @ 8 ohms. The bass is accurate, smooth, and not over powering. I can crank it and get the jail bail music if I want, but prefer my tight metal. The best part is the accuracy. It's focal. It's beautiful.
Pros: Everything above.
Cons: Would be nice to have a grill
