Short answer: the Neumann KH 150. It ranks #8 of 113 powered bookshelf speakers by sound quality (rated 4.8/5) at $3,398 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.
What the Focal Twin6 Be does well: The dual-woofer arrangement offers useful output capability for studio work, with a 48.3Hz measured -3dB point in the horizontal test. The catch: The horizontal measurement scores 6.06 with an ideal subwoofer and spans 2.9dB from 300Hz to 5kHz.
The Neumann KH 150 is the more accurate, deeper-bass pick. An exceptionally tight 1.0dB response span from 300Hz to 5kHz supports neutral vocals and instruments. Its measured preference score, a predictor of how neutral it sounds, is 6.65 against 4.04 for the Focal Twin6 Be. Its bass reaches about 39.6Hz before falling 3dB, against 48.3Hz for the Focal Twin6 Be. The tradeoff: A two-way nearfield monitor cannot match the largest three-way systems for deep-bass output at distance.
Buy the Neumann KH 150. It is rated higher for sound quality and still sold new, while the Focal Twin6 Be is discontinued.

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.

Neumann KH 150: $3,398 per pair B&H Photo Video eBay
Same family: the Neumann KH80 DSP (smaller bookshelf, rated 4.6/5), the Neumann KH120 MKII (smaller bookshelf, rated 4.7/5), the Neumann KH 310 A (larger bookshelf, ranked lower, rated 4.6/5), the Neumann KH420 (larger bookshelf, ranked higher, rated 4.8/5) and the Neumann KH 750 DSP (subwoofer, rated 3.5/5).
Pros: An exceptionally tight 1.0dB response span from 300Hz to 5kHz supports neutral vocals and instruments. The measured ideal-subwoofer score is 8.38, with -3dB bass extension to 39.6Hz. DSP and optional MA 1 alignment offer useful control over room-related response errors. Measured bass extension of 39.6Hz (-3dB).
Cons: A two-way nearfield monitor cannot match the largest three-way systems for deep-bass output at distance. Keep the tweeter near ear height to avoid crossover-related changes off the vertical axis. MA 1 calibration requires additional equipment, and studio connections are less convenient than a consumer streaming system.
