I think you will definitely notice a difference with the bigger 10" driver. All the subs you have listed are generally thought of as capable performers (even the Velodyne). If you want a more visceral feel get the larger sub. The Dayton is sealed, I believe, and the rest are ported. Shoot 2x6spds a pm, he has the Dayton as well as the Velo cht-10. The Dayton looks fun if you are into the DIY thing, and this one looks like it's easy. The Hsu will probably play the deeper notes with a bit more oomph. Good luck.
