Short answer: the Q Acoustics Q SUB120. It ranks #79 of 212 subwoofers by sound quality, rated 3.8/5, at $1,399; the ELAC Varro RS500 ranks #143, rated 3.6/5, at $1,399. Close enough in price that the sound-quality gap is the deciding factor.
The case for the Q Acoustics Q SUB120: Sealed 12 inch subwoofer with a 300W continuous (600W peak) amplifier, up from the 220W of the Q Acoustics Q B12 it replaces. Watch for: No independent measurements yet, so its output can’t be compared with ranked subwoofers; the rating is estimated from the measured Q Acoustics Q B12, which reached 115.2dB in the 40 to 80Hz CEA-2010 bands but only 98.4dB at 20Hz.
The case for the ELAC Varro RS500: Sealed reference enclosure with a 10-inch aluminum sandwich cone and HEX surround powered by a 500W RMS BASH amplifier. Watch for: Sealed alignment requires significant power down deep, resulting in lower maximum burst SPL than ported counterparts at 20Hz.
Buy the Q Acoustics Q SUB120. It is rated higher for sound quality than the ELAC Varro RS500 at the same price, so only choose the other one for a particular feature it does better.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: Q Acoustics Q SUB120 3.5 to 4.1; ELAC Varro RS500 3.4 to 3.8). Treat this verdict as provisional.

Q Acoustics Q SUB120: $1,399.00 Estimated Amazon Q Acoustics eBay
Older model: the Q Acoustics Q B12 (ranked higher, rated 3.8/5). See every Q Acoustics Subwoofers generation.
Pros: Sealed 12 inch subwoofer with a 300W continuous (600W peak) amplifier, up from the 220W of the Q Acoustics Q B12 it replaces. Onboard DSP adds automatic input detection, dual phase and delay controls, and a 40 to 250Hz low pass crossover for easier room integration. Q Acoustics rates it at 114dB maximum output and 28Hz at the -6dB point.
Cons: No independent measurements yet, so its output can’t be compared with ranked subwoofers; the rating is estimated from the measured Q Acoustics Q B12, which reached 115.2dB in the 40 to 80Hz CEA-2010 bands but only 98.4dB at 20Hz. As a sealed design it gives up some deep bass output to similarly priced ported subwoofers. At 22.5 kg it is heavy for its size.

ELAC Varro RS500: $1,399.00 Estimated Amazon Crutchfield eBay
Same family: the ELAC Varro RS700 (larger subwoofer, ranked higher, estimated 3.8/5).
Pros: Sealed reference enclosure with a 10-inch aluminum sandwich cone and HEX surround powered by a 500W RMS BASH amplifier. Provides excellent transient accuracy, lower group delay, and AutoEQ room correction down to 18Hz.
Cons: Sealed alignment requires significant power down deep, resulting in lower maximum burst SPL than ported counterparts at 20Hz. Premium pricing over the PS series.
