OK, now that my big living room sub is complete (and awesome), my little kitchen speakers need some help. I have a speaker terminal and a 200hz passive x-over, and my amp can give me a max of 40W rms @ 4 ohms. What can I do with this? I don't need this bad enough to beg the wife for another amp, nor do I have much space. I think I can fit a 5 1/4" driver in a box, but I've read that passive subs are very hard to get right. What am I looking for? I'm thinking a vented box with a 4 ohm DVC driver, maybe I can get it down to 40Hz or so?
The conditions you have listed are hardly ideal for a sub, but it's possible if you don't have to go too loud or low.
Try a small horn design like the Wicked One or the Table Tuba (with at least 8 inch drivers) to get the most of a small driver with very little power.
Google search will take you right to each of these designs and there are many more horn designs available but a bit bigger, like Cowan Audio's design for 2 10's. Horns are the only way to get satisfying bass with low power.

Sorry, I read that wrong. But my answer is the same for mains as well. Small horns are great and there are many designs available for small RLH horns as well that will work great with the power you have. You can even go full range and forget the crossover.
Horns sound great but I don't think I have the space. It would most likely go on top of my fridge with the mains, under a cabinet...about 7.5" high, maybe a foot wide and a foot deep but I can make a little more space there. the Tang Band W5-1138SG goes very low in a small ported box (flat to about 35Hz according to WinISD) but is single voice coil and only 82db sensitivity.
weirdly enough it modeled about the same, and actually dropped out a few Hz higher...
I could probably fit a 6-1/2" woofer though.
