Polk Audio Signature Elite ES10 Subwoofer vs Sony Bravia Theater Sub 9

Short answer: the Polk Audio Signature Elite ES10 Subwoofer. Both are rated 3.7/5 for sound quality (#112 and #84 of 212 subwoofers), and the Polk Audio Signature Elite ES10 Subwoofer costs $559 against $598 for the Sony Bravia Theater Sub 9, with sound quality a draw, the lower price decides it.

The case for the Polk Audio Signature Elite ES10 Subwoofer: The 10” subwoofer of Polk’s Signature Elite range and the replacement for the Polk Audio HTS 10. 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 10 it replaces, which reached 114.8dB in the 40 to 80Hz CEA-2010 bands but only 86.1dB at 20Hz.

Why pick the Sony Bravia Theater Sub 9: Independent CEA-2010 testing records 98.0 dB at 20 Hz and 112.8 dB through 40-80 Hz. Watch for: The 390.0H x 400.0W x 350.0D mm cabinet and 51.4 lbs (23.3 kg) mass still need deliberate placement.

Buy the Polk Audio Signature Elite ES10 Subwoofer. Both are rated the same for sound quality, and it costs $39 less than the Sony Bravia Theater Sub 9.

About the ratings: the Polk Audio Signature Elite ES10 Subwoofer’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.3 to 3.9, so this verdict could change once it is measured.
