Short answer: the Genelec 7040A, though neither ranks well in its class. It ranks #65 of 73 subwoofers by sound quality, rated 2.7/5, at $1,125; the KEF KC62 ranks #212, rated 2.5/5, and costs $1,579.95, which makes this an easy call rather than a real tradeoff. Both are rated below 3.0/5 among the 73 subwoofers; for better sound, the Edifier T5s ranks #2 at $199.99.
Why pick the Genelec 7040A: A compact studio subwoofer with balanced XLR inputs and built in bass management, made to pair with small desktop monitors. The tradeoff: No independent measurements yet, so its output can’t be compared with ranked subwoofers.
What the KEF KC62 does well: A tiny sealed subwoofer with two opposing 6.5 inch drivers and placement EQ presets, sized to fit almost any room’s decor. The catch: A hard limiter caps low bass as you turn it up: at 85 to 90dB it plays about 74dB at 20Hz, 6dB below the KEF KF92, and 10Hz output is about 15dB lower.
Buy the Genelec 7040A. It is rated higher for sound quality than the KEF KC62 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
About the ratings: the Genelec 7040A’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 2.5 to 2.9, so this verdict could change once it is measured.
