Short answer: the KRK S10.4. Both are rated 3.6/5 for sound quality (#146 and #141 of 212 subwoofers), and the KRK S10.4 costs $479 against $499 for the ELAC SUB3010, and with sound quality even, the cheaper one is the better buy.
Why pick the ELAC SUB3010: 10-inch woofer with 10-inch passive radiator delivers tight punchy bass.
The case for the KRK S10.4: 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 catch: 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.
Buy the KRK S10.4. Both are rated the same for sound quality, and it costs $20 less than the ELAC SUB3010.
About the ratings: the KRK S10.4’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.2 to 3.8, so this verdict could change once it is measured.
