Short answer: both are discontinued, so this only matters if you are buying used. Used, the Genelec 8040B is the better pick: it ranks #54 of 113 powered bookshelf speakers by sound quality (rated 4.3/5), against #101 (rated 3.8/5) for the Focal Twin6 Be. If you want one new, the Genelec 8340A replaces the Genelec 8040B and is rated 4.4/5 at $3,790.
Why pick the Focal Twin6 Be: The dual-woofer arrangement offers useful output capability for studio work, with a 48.3Hz measured -3dB point in the horizontal test. The tradeoff: The horizontal measurement scores 6.06 with an ideal subwoofer and spans 2.9dB from 300Hz to 5kHz.
The Genelec 8040B is the better-sounding pick. A compact professional monitor with balanced XLR input and analog room-adjustment controls. Watch for: It lacks GLM calibration and consumer streaming inputs.
Buy the Genelec 8040B only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the Genelec 8340A, which replaces the Genelec 8040B.

Focal Twin6 Be Discontinued eBay
Newer model: the Focal ST6 Twin6, ranked lower, estimated 3.8/5.
Pros: The dual-woofer arrangement offers useful output capability for studio work, with a 48.3Hz measured -3dB point in the horizontal test. Its professional controls and format can suit a dedicated monitoring installation. Measured bass extension of 48.3Hz (-3dB).
Cons: The horizontal measurement scores 6.06 with an ideal subwoofer and spans 2.9dB from 300Hz to 5kHz. Off-axis variation limits tonal consistency across listening positions. Orientation matters, and neither the beryllium tweeter nor the additional woofer makes its measured balance class-leading. Erin suspected intermodulation-related roughness even though harmonic distortion measured low. Discontinued.

Genelec 8040B: $2,790 per pair Discontinued B&H Photo Video eBay
Newer model: the Genelec 8340A, ranked higher, estimated 4.4/5. It uses the same cabinet and woofer size, adding GLM room calibration and an AES/EBU digital input.
Same family: the Genelec 8010A (smaller bookshelf, rated 4.5/5), the Genelec 8020D (smaller bookshelf, rated 4.4/5), the Genelec 8030C (smaller bookshelf, rated 4.6/5) and the Genelec 8050B (larger bookshelf, ranked higher, rated 4.4/5).
Pros: A compact professional monitor with balanced XLR input and analog room-adjustment controls. The manufacturer’s 41Hz limit is specified at -6dB, offering a useful reference for system planning without confusing it with a measured -3dB point.
Cons: It lacks GLM calibration and consumer streaming inputs. The balanced XLR connection may require an interface or controller for a typical desktop source. It is expensive. Discontinued.
