HDC can easily be an SQL sub in the right enclosure. I enjoy the sound of mine and they do get loud.
Q would also do very well off the power you have, but can be bottom heavy, so a little EQ down low would help.
Ran RL-P's a few years ago, but the sound was kind of dry to me, just didn't have enough punch. But I like my music VERY loud at times, so that could be why.
Honestly most of the subs listed could sound good for daily and get respectably loud. Building the right enclosure will make a big diff and getting the sub to blend with your front stage...
