Short answer: the Bose Lifestyle Ultra Subwoofer. Both are rated 3.8/5 for sound quality (#50 and #82 of 212 subwoofers), and the Bose Lifestyle Ultra Subwoofer costs $849 against $899 for the Polk Audio Signature Elite ES12 Subwoofer, so with nothing between them on sound quality, price settles it.
The case for the Bose Lifestyle Ultra Subwoofer: Independent CEA-2010 testing records 90.6 dB at 20 Hz and 115.4 dB (avg of 3/4 bands) through 40-80 Hz. The tradeoff: The 326.8H x 294.7W x 294.7D mm cabinet and 33.7 lbs (15.3 kg) mass still need deliberate placement and calibration.
Why pick the Polk Audio Signature Elite ES12 Subwoofer: The 12” subwoofer of Polk’s Signature Elite range, replacing the Polk Audio HTS 12. The catch: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured Polk Audio HTS 12 it replaces (113.5dB in the 40 to 80Hz CEA-2010 bands); its 300W amplifier should give it a little more output.
Buy the Bose Lifestyle Ultra Subwoofer. Both are rated the same for sound quality, and it costs $50 less than the Polk Audio Signature Elite ES12 Subwoofer.
Worth knowing: the Polk Audio Signature Elite ES12 Subwoofer has not been measured yet. Its rating is estimated from related models, with a likely range of 3.4 to 4.0, so treat this verdict as provisional.
