Short answer: a tie on sound quality. Both are rated 3.8/5 (#73 and #82 of 212 subwoofers) at nearly the same price ($899.99 vs $899), so choose on features and fit.
Why pick the Klipsch RP-1200SW: The sweet-spot 12-inch model in Klipsch’s Reference Premiere subwoofer series. Watch for: A heavy, deep enclosure (31.1 kg, 598 mm deep) that demands meaningful floor space.
What the Polk Audio Signature Elite ES12 Subwoofer does well: 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 Klipsch RP-1200SW or the Polk Audio Signature Elite ES12 Subwoofer on features: they are rated the same for sound quality at close to the same price.
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.

Klipsch RP-1200SW: $899.99 each Amazon eBay
Same family: the Klipsch RP-1000SW (smaller subwoofer, ranked lower, rated 3.6/5), the Klipsch Reference Premiere RP-1400SW (larger subwoofer, estimated 4/5) and the Klipsch RP-1600SW (larger subwoofer, rated 4.2/5).
Pros: The sweet-spot 12-inch model in Klipsch’s Reference Premiere subwoofer series. Delivers 400W RMS / 800W peak power driving an ultra-long-throw 12-inch front-firing Cerametallic woofer through a front Aerofoil slot port. Audioholics comprehensive CEA-2010 bench testing proved class-leading output across the sub-bass spectrum, producing 105.8dB at 20Hz and over 117dB above 40Hz with remarkably low harmonic distortion. Rivals established internet-direct heavyweights like SVS and Monolith in clean output capability.
Cons: A heavy, deep enclosure (31.1 kg, 598 mm deep) that demands meaningful floor space. Lacks app-based parametric EQ or DSP presets found on competitors like SVS Pro models.
