I'm trying to figure out what to do Sub wise in my new setup.

I am going to have a room that is 18'x25' with a 13' foot vaulted ceiling. The back of this room is not enclosed, because it goes into my dining room and kitchen.

So it's not ideal shape, but it's all I got. Right now I have a SVS PB12-ISD. I was thinking about going to a EP500, and wondering if I would notice a significant differene of this change. Also would it be a lot better to place 2 EP500 in this room. I watch a lot of movies and listen to music. 70/30 movies to music.

I don't think my wife will let me get away with EP600 or 800.

What would you all do in this space?
