it all depends on what you use them for. In a daily setup that you want the cleanest, best sounding sub you can get, and still be loud enough in a daily driver, I would pick the W7 every day. It's built pretty nicely and doesn't NEED a recone if you install and tune it all right. I don't see why the recone option being mandatory, Sonic, if he is just trying to get bass.
If burping loud numbers with no regard for sound is the goal, shit yeah get the Kicker. But EXPECT to be reconing it.
