Short answer: the ADAM Audio A77H. It ranks #45 of 118 powered bookshelf speakers by sound quality, rated 4.4/5, at $2,799.98; the Focal Solo6 ST6 ranks #53, rated 4.3/5, and costs $2,998, so there is not much of a tradeoff to weigh.
Why pick the ADAM Audio A77H: Horizontally configured true 3-way studio monitor featuring dual 7-inch MLM woofers, a dedicated 3.5-inch midrange, and a rotatable X-ART tweeter. Watch for: Rating estimated based on A-Series sibling measurements.
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 ADAM Audio A77H. 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.
About the ratings: the ADAM Audio A77H’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 4.2 to 4.6, so this verdict could change once it is measured.

Same family: the ADAM Audio A4V (smaller bookshelf, rated 3.6/5), the ADAM Audio A44H (smaller bookshelf, estimated 3.8/5), the ADAM Audio A7V (smaller bookshelf, ranked lower, rated 4/5) and the ADAM Audio A8H (smaller bookshelf, ranked higher, estimated 4.4/5). See every ADAM Audio A Series generation.
Pros: Horizontally configured true 3-way studio monitor featuring dual 7-inch MLM woofers, a dedicated 3.5-inch midrange, and a rotatable X-ART tweeter. Tri-amped with 340W of Class-D/AB amplification and onboard DSP supporting automated room calibration via Ethernet. Dual 7-inch drivers produce massive acoustic power and effortless low-end output down to 37Hz with wide horizontal soundstaging for midfield listening.
Cons: Rating estimated based on A-Series sibling measurements. Wide 531mm horizontal form factor requires a broad mixing console bridge or dedicated horizontal stands; careful acoustic alignment needed in asymmetric control rooms.

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). See every Focal Twin6, Solo6 and Trio6 generation.
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.
