Help picking a sub please

[antimatter]

Hey guys I am setting up a ht at my girls bedroom kind of a ht away from home well I moved in with her parents and out of my parents house I still enjoy mine every other weekend and 1 time every week. I have a SUVs pb12 nds. In my ht. bedroom of 12Wx20L I believe. But her room is larger. I have pretty much everything decided/installed Vizio e600i-b2. We are buying the 5.0 pioneer fs-52 set and adding the additional bs-22 to make it 7.0 this weekend. If I hadn't to guess her room size 30-40L x 20W not sure I can post back Sunday night when I am able to measure. Further info This would remain a bedroom set or living room/front room set. So it would remain a secondary setup. Plus I still consider myself an extreme novice.

I am looking to spend $500 maybe 550 max. I was looking for something to make the movies rock. I am currently mulling over 2and have almost ruled out a third, but am open to other suggestions I can review. I am looking to purchase in 2 weeks.

I am more concerned with movies than music but we may listen to a bit but no where near like a movie at reference levels.

I have interest in:
SVS pb-1000
Hsu Vtf-1 mk-2 (maybe mk-4 if it would make a huge diff. At 250rms-1000peak)
The bic pl-200 but read a lot about how muddy it is. So this is looking to be on the out.

Please help in anyway you can. Pros cons of each, your experience, or recommendations. NOTE the floor is carpeted but not thick almost like a throw rug but fully carpeted. Also is downward or front better especially with carpet.

As a side note we are more than 12ft (may eventually sit closer)from main speakers do you think at 35-3/16 tall the fronts are ok should I make a riser of 3.5 putting it at 38.5 inches high.
Thank you so much!
