Hey Taje, you pose an interesting question especially considering the size of your room(s). Without including your kitchen you have to pressurize 4000 cu ft. That's a large room. With your kitchen you have 6000 cu ft to pressurize. No matter how you look at it though, its a large space and you will need a powerful sub to adequately pressurize the room.
I have a HT of 3250 cu ft with a small hall opening to the rest of the basement. When I emailed SVS and PSA about the size of the space, which is a bit smaller than yours, they both strongly suggested ported subs because they do a better job for large spaces. Now, I know that a lot of guys in the forums have sealed subs in large spaces but most of them have more than one to be able to handle the space.
My concern is whether any of these sealed subs by itself will be able to meet your needs. But I might be wrong. I'm not trying to spend your money or steer you towards something you said you don't want, but there won't be any point in spending any money if you still don't get what you want in the end.
Personally, I would think the least you need for your space is either dual sealed subs or a single ported sub like the Rythmik FV15HP, PSA XV15 or the XV30, SVS PB12+, PB13 Ultra or the Hsu VTF-15H (of course dual ported subs would be better but I know that's out of the question).
With the options you presented I would say go with the SB 13 Ultra myself. I also would not worry about Hsu or SVS in quality especially since SVS has a 5 year warranty and free shipping and are well known for their excellent customer service. Hsu, PSA and Rythmik are also very well respected.
