Be-718 owners, what sub are you using?

I'm planning to add a subwoofer to fill in the lower octave. My room is 15x24 and I listen mostly to 2-channel jazz and indie rock (80%). I also watch movies from time to time in the same room, 2-channel only.

I've been looking at JL Audio and am leaning in that direction. I'd welcome any advice from others who are using the Tiny Dancers (Usher Be-718s).

What subs have you found easy to integrate?

Thanks in advance.
