The PV1 won't stand much of a chance in that size room. Bigger is better in this respect, and you'll have to look at much bigger subs to get decent performance at higher, or even lower, volumes. I wouldn't really recommend satellites in that size room either, unless they were M&K (M series for example) as they tend to be able to handle a little more power than most. Although recommendations would depend on your listening levels.
