Short answer: the SVS SB-5000 R-Evolution, if you are buying new. The SVS SB-4000 measures as well as it (#70 vs #79 of 143 subwoofers, 4.2/5 vs 4.2/5) but is discontinued, so only consider it used; the SVS SB-5000 R-Evolution is still sold new at $1,799.
Why pick the SVS SB-5000 R-Evolution: A sealed 15 inch subwoofer with a powerful amplifier and app based room calibration for tight, deep bass. The catch: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured SVS SB-4000 it replaces (120.1dB in the CEA-2010 bands it completed).
The case for the SVS SB-4000: A sealed 13.5 inch subwoofer with punchy, tight upper bass in a compact cabinet for movies and music. The catch: 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 SVS SB-5000 R-Evolution, since the SVS SB-4000 is discontinued and only worth hunting down used.
Worth knowing: the SVS SB-5000 R-Evolution has not been measured yet. Its rating is estimated from related models, with a likely range of 4.0 to 4.4, so treat this verdict as provisional.
