For $1000, you do have quite a range of choice. Do you have room for a larger sub, or are you limited by space.

If you have the space, I would go for a larger ported sub with an 18" driver. When it comes to low frequencies, there is no replacement for displacement, and ported subs are more efficient in output. ED, SVS EPIC and HSU all make good subs.
