Help with choosing midbass woofer

Hi All
I was wondering if you can help
I am looking for a midbass woofer that I will use in my car in a sealed box, the box will be around 15L and in a sealed application.
I need the woofer to play from 45 to about 140hz, I need it to have good xmax, be sensitive and good power output.
I want something as accurate/snappy as possible.
Can you guys recommend any woofers to do this?
Also what TS specs would be most suited for this application?
Many thanks
