Will this help with not interrupting my neighbors? Or will the sound still travel and rattle their apartment?
Sound travels regardless, so the best you can hope to do is mitigate some of the unwanted ramifications. Looking at subwoofers with modest outputs, using a SubDude and running it at conservative volume levels are all anyone can really expect, so I think you should be fine. There are many people in apartments who have a sub, yet few go to the lengths you're contemplating, which strikes me as very considerate.

My suggestion was based upon the fact you seemed adamant about not wanting to impact any of your neighbors. There are those who say it makes no difference when it comes to output -- front firing vs. down firing -- but my experience runs counter to that position. I've found front firing will often have a more direct sound, while down firing typically creates more of that tactile sensation of "feel". Based upon what you're saying the latter is not what you want. However, therein lies a quandary...
If you try and eliminate too much of the bass you might as well not even have a subwoofer, but achieving that balance can sometimes be difficult. The SubDude will definitely help. Since you're heading in the right direction I think it might be better to concentrate on something that will satisfy your needs now, otherwise you may find that you've done all this for nothing and spent money without getting what you were after.

Given that I don't like want it to be too loud and I'd probably set the sub on the lower volume settings (if this is recommended), what's the problem with having a sub that is underpowered for the area? And more theoretically, why do I need to get a sub large enough for the entire room, even though I don't listen to music or movies in the other half of the room, which is the kitchen area?
A subwoofer does not acknowledge "imaginary" boundaries, only physical ones. In other words, even though you consider the listening area to be 8x10 the subwoofer sees 20x10 instead. A sub needs to "pressurize" the entire space you put it in, so the complete area within the physical boundaries is what you really need to consider when sizing a sub. It may not seem to make much sense, but it's actually how they function.
That's precisely why everyone is contending most 10" subwoofers would struggle. You've probably already seen it mentioned in multiple threads, but it's better to have too much sub than too little. You can always turn it down, but there is a limit to how far you can turn it up. If the sub you buy proves insufficient there's nothing that can be done (short of getting another sub, of course).
There are instances where getting two subs can be better than one large sub, but that depends upon a number of factors. Duals will not really give you additional low frequency extension, just additional output and a more even sound distribution. That may be something to consider as well.

By most accounts the 10.3 is thought to be a nice subwoofer, and that's a good price for it too. I do have some reservations about whether it will have enough output though. Is $250 your budget, or was that just one of the units you were considering?
