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; the Focal Solo6 ST6 ranks #51, rated 4.3/5, and costs $2,998, which makes this an easy call rather than a real tradeoff.
What the Kali Audio IN-8 V2 does well: The IN-8 V2’s coaxial midrange/tweeter supports coherent imaging, and low distortion at ordinary levels complements its 7.30 ideal-subwoofer score. Watch for: The measured 3.0dB response span from 300Hz to 5kHz includes unevenness that can make some vocals sound forward.
Why pick the Focal Solo6 ST6: ASR measured a tight 1.6dB response span from 300Hz to 5kHz and a 7.34 ideal-subwoofer score, supporting accurate midrange monitoring. The catch: The measured -3dB point is 46.9Hz, so deep-bass work benefits from a subwoofer.
Buy the Kali Audio IN-8 V2. It is rated higher for sound quality than the Focal Solo6 ST6 and costs less, so only choose the other one for a particular feature it does better.

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.

Focal Solo6 ST6: $2,998 per pair B&H Photo Video eBay
Same family: the Focal ST6 Twin6 (larger bookshelf, ranked lower, estimated 3.8/5) and the Focal Trio6 ST6 (larger bookshelf, ranked lower, rated 4.2/5).
Pros: ASR measured a tight 1.6dB response span from 300Hz to 5kHz and a 7.34 ideal-subwoofer score, supporting accurate midrange monitoring. The beryllium tweeter and Focus mode offer a useful professional workflow, with Focus serving as an alternate mix-check presentation. Its beryllium inverted-dome tweeter and 6.5-inch W composite sandwich-cone woofer are a low-mass, low-distortion pairing. Measured bass extension of 46.9Hz (-3dB).
Cons: The measured -3dB point is 46.9Hz, so deep-bass work benefits from a subwoofer. The standard-mode score does not apply to Focus mode. There is no automatic room-calibration system, and premium driver materials alone do not establish superior sound.
