Short answer: the Kali Audio IN-8 V2. It ranks #38 of 113 powered bookshelf speakers by sound quality (rated 4.4/5) at $998 and is still sold new; the Focal Twin6 Be ranks #101 (rated 3.8/5) and is discontinued, so it is only an option used. The Focal Twin6 Be’s replacement, the Focal ST6 Twin6, is rated 3.8/5.
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 Kali Audio IN-8 V2 is the more accurate pick. The IN-8 V2’s coaxial midrange/tweeter supports coherent imaging, and low distortion at ordinary levels complements its 7.30 ideal-subwoofer score. Its measured preference score, a predictor of how neutral it sounds, is 5.36 against 4.04 for the Focal Twin6 Be. The catch: The measured 3.0dB response span from 300Hz to 5kHz includes unevenness that can make some vocals sound forward.
Buy the Kali Audio IN-8 V2. It is rated higher for sound quality; the Focal Twin6 Be is no longer sold new.

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.

Kali Audio IN-8 V2: $998 per pair Amazon eBay
Same family: the Kali Audio IN-5 (smaller bookshelf, rated 4.2/5) and the Kali Audio IN-UNF (larger bookshelf, rated 3.3/5).
Pros: The IN-8 V2’s coaxial midrange/tweeter supports coherent imaging, and low distortion at ordinary levels complements its 7.30 ideal-subwoofer score. Measured -3dB extension of 45.4Hz provides useful bass; boundary settings assist placement. The front port allows placement near a wall without port noise problems. Measured bass extension of 44Hz (-3dB), with a measured sensitivity of 89dB.
Cons: The measured 3.0dB response span from 300Hz to 5kHz includes unevenness that can make some vocals sound forward. Bass and limiter behavior constrain high-level playback. These measurements apply to the V2, not the first-generation IN-8. On-axis, the 4 to 5kHz range sounds forward; Kali recommends about 10° of toe-out, and some EQ helps.
