Short answer: the RSL (Rogersound Labs) Speedwoofer 10E. It ranks #183 of 212 subwoofers by sound quality, rated 3.3/5, at $339.34; the Polk Audio Signature Elite ES8 Subwoofer ranks #195, rated 3.2/5, and costs $359, which makes this an easy call rather than a real tradeoff.
Why pick the RSL (Rogersound Labs) Speedwoofer 10E: Independent CEA-2010 testing records 94.0 dB at 20 Hz and 107.3 dB through 40-80 Hz. The catch: The boxy cabinet skips the rounded edges of pricier subs in the lineup.
The case for the Polk Audio Signature Elite ES8 Subwoofer: The smallest subwoofer in Polk’s Signature Elite range, matching the ES speakers in style. Watch for: 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, the 10” sub this range replaces (114.8dB in the 40 to 80Hz CEA-2010 bands).
Buy the RSL (Rogersound Labs) Speedwoofer 10E. It is rated higher for sound quality than the Polk Audio Signature Elite ES8 Subwoofer and costs less, so only choose the other one for a particular feature it does better.
About the ratings: the Polk Audio Signature Elite ES8 Subwoofer’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 2.8 to 3.5, so this verdict could change once it is measured.

Polk Audio Signature Elite ES8 Subwoofer: $359.00 Estimated Amazon eBay
Same family: the Polk Signature Elite ES10 (smallest bookshelf, estimated 3.1/5), the Polk Signature Elite ES15 (bookshelf, rated 3.5/5), the Polk Signature Elite ES20 (largest bookshelf, rated 3.7/5), the Polk Signature Elite ES50 (smallest floorstanding, estimated 3.8/5), the Polk Signature Elite ES55 (floorstanding, estimated 4/5), the Polk Signature Elite ES60 (largest floorstanding, rated 3.4/5), the Polk Audio Signature Elite ES30 (smaller center, estimated 3.5/5), the Polk Audio Signature Elite ES35 (larger center, estimated 3.4/5), the Polk Audio Signature Elite ES10 Subwoofer (larger subwoofer, ranked higher, estimated 3.7/5) and the Polk Audio Signature Elite ES12 Subwoofer (larger subwoofer, ranked higher, estimated 3.8/5). See every Polk Signature generation.
Pros: The smallest subwoofer in Polk’s Signature Elite range, matching the ES speakers in style. An 8” mineral-filled polypropylene woofer and twin Power Ports are driven by a 100W amplifier with DSP and Polk’s Time-Smart phase control, rated to 32Hz.
Cons: 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, the 10” sub this range replaces (114.8dB in the 40 to 80Hz CEA-2010 bands). With a smaller woofer and a third of the newer models’ power, it is suited to small rooms.
