Short answer: the REL Acoustics S/550. It ranks #155 of 212 subwoofers by sound quality, rated 3.5/5, at $3,299. The Genelec 7360A ranks #186, rated 3.3/5, at $2,795, $504 cheaper, not enough of a saving to outweigh the sound-quality gap.
Why pick the REL Acoustics S/550: The smallest model in REL’s 2025 Serie S, replacing the S/510: a 10” CarbonAlloy active driver and a 12” down-firing passive radiator driven by a 550W Linear Class D amplifier, reaching 19Hz (-6dB). The tradeoff: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured REL Acoustics R-528 (112.8dB in three of the four 40 to 80Hz CEA-2010 bands) and its sibling REL Acoustics S/850.
The case for the Genelec 7360A: 10-inch (250mm) driver with a 300W Class D amplifier. Watch for: No independent measurements yet, so its output can’t be compared with ranked subwoofers.
Buy the REL Acoustics S/550. It is rated higher for sound quality, and the $504 you would save on the Genelec 7360A does not close the gap.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: REL Acoustics S/550 3.1 to 3.7; Genelec 7360A 3.1 to 3.5). Treat this verdict as provisional.

REL Acoustics S/550: $3,299.00 Estimated Audio Advice eBay
Same family: the REL Acoustics S/850 (larger subwoofer, ranked higher, estimated 3.7/5), the REL Acoustics Carbon Special Black Label (larger subwoofer, estimated 3.9/5) and the REL Acoustics 212 Black Label (larger subwoofer, estimated 4.2/5). See every REL S and Reference Series generation.
Pros: The smallest model in REL’s 2025 Serie S, replacing the S/510: a 10” CarbonAlloy active driver and a 12” down-firing passive radiator driven by a 550W Linear Class D amplifier, reaching 19Hz (-6dB). It includes REL’s high-level speaker connection for integrating with stereo amplifiers.
Cons: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured REL Acoustics R-528 (112.8dB in three of the four 40 to 80Hz CEA-2010 bands) and its sibling REL Acoustics S/850. It is placed below the larger REL Acoustics S/850, and at 31.7kg it is heavy for a 10” sub.

Older model: the Genelec 7060B (ranked higher, rated 3.3/5). See every Genelec 7000 and 7300 Subwoofers generation.
Same family: the Genelec 7350A (smaller subwoofer, ranked lower, estimated 3/5), the Genelec 7370A (larger subwoofer, estimated 3.6/5), the Genelec 7380A (larger subwoofer, estimated 3.9/5) and the Genelec 7382A (larger subwoofer, estimated 4.1/5).
Pros: 10-inch (250mm) driver with a 300W Class D amplifier. Genelec rates it at 19-100Hz within 3dB and 109dB short-term maximum output. Analog and AES/EBU digital XLR inputs and outputs, and GLM network control with AutoCal 2 room calibration.
Cons: No independent measurements yet, so its output can’t be compared with ranked subwoofers. Room calibration needs Genelec’s GLM kit or 9320A controller, sold separately.
