My room is 21x16x13, 4000 sq ft, vaulted ceiling, open on the back side partially. I have a large entertainment center on the front wall, a sub or subs can flank the entertainment center or go in a corner. I listen to music most the time and a movie once a week. My budget is around 2000. I've narrowed down my choices to dual empires, dual VTF-15Hs, JTR Captivator, or a Submersive HP. My current subs are a Deftech Powerfield 1500 and a Klipsch 12. I'm sure any of my choices will be satisfying. I'm not going to return any subs, just to much trouble, so this is one and done for me. Any thoughts are appreciated. I'm leaning toward the empires as I usually prefer duals over a single however I've never had a single with as much force as a Capitivator or Submersive.
