I like what I read about the EMP speakers, so that looks like a good set. The SVS subs are fine, but I would switch that up to a Hsu VTF3 mk5, it costs a tad more but it will offer a lot more performance. In that room you will want a ported sub, not a sealed sub. A sealed sub will lose a lot of low end output, so not nearly as much deep bass for movies. If you wanted a DIY project, I would be looking at a ported subwoofer, either that or a sealed with a very high excursion 18" driver, like the Stereo Integrity HST18.
