Short answer: the KRK S10.4. It ranks #146 of 212 subwoofers by sound quality, rated 3.6/5, at $479; the ELAC Debut 3.0 DS103 ranks #156, rated 3.5/5, at $479. Close enough in price that the sound-quality gap is the deciding factor.
What the KRK S10.4 does well: The 10” studio subwoofer in KRK’s fourth generation, with a glass aramid woofer, a 160W Class D amplifier and a four-position crossover. The tradeoff: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from KRK’s measured 12S (117.1dB in the 40 to 80Hz CEA-2010 bands), which it is not expected to match.
What the ELAC Debut 3.0 DS103 does well: The 10” sealed subwoofer of ELAC’s Debut 3.0 line, which follows the Debut 2.0 range of the ELAC SUB3010. Watch for: No independent measurements yet, so its output can’t be compared with ranked subwoofers.
Buy the KRK S10.4. It is rated higher for sound quality than the ELAC Debut 3.0 DS103 at the same price, which makes it the one to get unless you need something the other one does better.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: KRK S10.4 3.2 to 3.8; ELAC Debut 3.0 DS103 3.1 to 3.9). Treat this verdict as provisional.

ELAC Debut 3.0 DS103: $479.00 Estimated Amazon eBay
Older model: the ELAC SUB3010 (ranked higher, rated 3.6/5). See every ELAC Debut Subwoofers generation.
Pros: The 10” sealed subwoofer of ELAC’s Debut 3.0 line, which follows the Debut 2.0 range of the ELAC SUB3010. ELAC rates it to 31Hz (-3dB) with a 100W RMS (200W peak) Class D amplifier, and it has LFE, stereo RCA and high-level inputs.
Cons: No independent measurements yet, so its output can’t be compared with ranked subwoofers. Its 100W RMS amplifier is smaller on paper than the SUB3010’s, which limits headroom in larger rooms.
