Short answer: the Genelec 8040B. It ranks #9 of 66 powered bookshelf speakers by sound quality at $2350; the Genelec S360 ranks #27 and costs $4775, so there is not much of a tradeoff to weigh.
What the Genelec 8040B offers: Based on their smaller speaker’s performance against others, I’m ranking this accordingly. Watch for: Very expensive
What the Genelec S360 offers: A large format 10 inch two way monitor built for main monitoring duty in film and post production, capable of a peak SPL over 128dB while retaining Genelec’s GLM calibrated Smart Active Monitoring and Directivity Control Waveguide. Listening window smoothness measures a solid 0.52 and the measured extension point reaches 39.6Hz, unusually deep for a monitor this size. Watch for: The bass alignment measures the highest Q of any speaker in this batch, 1.16, meaning it’s the most likely of the ten to show a mild bump near its port tuning frequency rather than a clean rolloff. On axis deviation measures a moderate 0.478dB average. At roughly $9,550/pair and 30kg (66 lbs) each it is one of the largest and most expensive entries in this catalog, intended for professional control rooms rather than home listening, and the model has since been updated to the S360A, so pricing and minor spec details should be confirmed with a dealer before buying.
Buy the Genelec 8040B. It ranks higher for sound quality than the Genelec S360 and costs less, so there is no real case for the other one.
