musical subwoofer recommendation for 2-ch

Can someone recommend good subwoofers for 2-ch listening? I recently purchased a pair of very articulate speakers made by JAS audio. They have small woofers and so they are fast but do not have sufficient low bass.

I have a 15" Velodyne SPL-1500R. It is very powerful. But it is too slow to match up these speakers. So I'll save it for HT applications.

I am thinking to get two 10" subwoofers and connect them to the speakers. Is this a good idea? What are the good subwoofers I should consider?

Thanks in advance.
