Out of the 3 subs you've mentioned, the Klipsch holds the most value. They run approximately $400 here in the U.S. Obviously, if it costs you a ridiculous sum of money for a $500 U.S. SVS PB-1000, just get the Klipsch. It looks like a capable subwoofer for a small room, but should do pretty well in your 2,000 plus cu.ft. room. That Paradigm runs around $900 in the U.S. and is NOT a good value here.
