Short answer: the Paradigm Signature Sub 2, if you are buying new. The Reaction Audio PS-15X measures as well as it (#32 vs #33 of 143 subwoofers, 4.3/5 vs 4.3/5) but is discontinued, so only consider it used; the Paradigm Signature Sub 2 is still sold new at $9,494.56.
The case for the Paradigm Signature Sub 2: A sealed subwoofer with six 10 inch drivers, strong deep bass, and flexible stereo, LFE, and balanced inputs. The tradeoff: The 622.3H x 603.2W x 568.2D mm cabinet and 229.9 lbs (104.3 kg) mass make this a serious placement and moving commitment.
Why pick the Reaction Audio PS-15X: A 15 inch rear ported subwoofer with strong upper bass punch for movie effects and music in a compact cube. Watch for: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority.
Buy the Paradigm Signature Sub 2 new; the Reaction Audio PS-15X is no longer sold new, so it only makes sense as a used find.
