Short answer: the Klipsch Flexus Sub 100. It ranks #16 of 48 subwoofers by sound quality, rated 3.4/5, at $349.99; the ELAC SUB1010 ranks #26, rated 3.3/5, and costs $550, so there is not much of a tradeoff to weigh.
What the Klipsch Flexus Sub 100 does well: Independent CEA-2010 testing records 90.2 dB at 20 Hz and 109.1 dB (avg of 3/4 bands) through 40-80 Hz. The catch: Only works with Klipsch Flexus soundbars, not as a standalone LFE sub.
What the ELAC SUB1010 does well: A compact 10-inch ported subwoofer with useful measured output through the upper-bass range: 102.7dB at 40Hz and 110.8dB at 63Hz. The tradeoff: Deep-bass output is limited compared with larger subwoofers, with 96.5dB measured at 31.5Hz, so it is not the right choice for demanding home-theater effects or a large room.
Buy the Klipsch Flexus Sub 100. It is rated higher for sound quality than the ELAC SUB1010 and costs less, which makes it the one to get unless you need something the other one does better.

Klipsch Flexus Sub 100: $349.99 Amazon eBay
Pros: Independent CEA-2010 testing records 90.2 dB at 20 Hz and 109.1 dB (avg of 3/4 bands) through 40-80 Hz. The sealed enclosure with a 10” driver suits a small room.
Cons: Only works with Klipsch Flexus soundbars, not as a standalone LFE sub. The 339.9H x 335.0W x 349.2D mm cabinet and 9.4 kg mass still need deliberate placement.

ELAC SUB1010: $550 eBay
Pros: A compact 10-inch ported subwoofer with useful measured output through the upper-bass range: 102.7dB at 40Hz and 110.8dB at 63Hz. Its small cabinet makes it an approachable option for a modest room or a first 2.1 setup, where careful placement can add satisfying weight without taking much floor space.
Cons: Deep-bass output is limited compared with larger subwoofers, with 96.5dB measured at 31.5Hz, so it is not the right choice for demanding home-theater effects or a large room. Ported-room placement can also become boomy; experiment with position and crossover rather than expecting a plug-and-play upgrade.
