The SX is more of a spl sub.

I could let you hear my friend's single 12'' Fi Q off 1200rms(2.5 cubes, 32hz). It is in the trunk of his e46 coupe. Very nice sound and digs quite low. I am actually building a TC9 12'' for myself which is pretty close in design to the Fi Q. I just need something smaller for when I don't feel like carting around the 70lb XXX lol.
