CDT HD10 or RE SE10

I want a sub that has good SQ with some decent output and low end. But mostly SQ. Its going in a Civic in a FG box. Anyone have any opinions on either one? Or anything else that would be comparable for around $300?

Fi Q

Ill check it out thanks,

I went with a Sound Integrity MAG, the Fi is a good sub too. CDT is an average brand to me now, I ran their HD 52 set in comps the last 2 years.
