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 Genelec G Four ranks #67, rated 4.2/5, at $2,790, $9.98 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the ADAM Audio A77H does well: 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. The tradeoff: Rating estimated based on A-Series sibling measurements.
What the Genelec G Four does well: A home speaker built on the drivers and waveguide of the Genelec 8040B studio monitor: a 6.5” woofer and 0.75” metal-dome tweeter in a die-cast aluminum cabinet, each with its own 90W amplifier. Watch for: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Genelec 8040B it is based on.
Buy the ADAM Audio A77H. It is rated higher for sound quality, and saving $9.98 with the Genelec G Four does not make up for the sound-quality gap.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: ADAM Audio A77H 4.2 to 4.6; Genelec G Four 3.9 to 4.5). Treat this verdict as provisional.

ADAM Audio A77H: $2,799.98 per pair Estimated Amazon eBay
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.

Genelec G Four: $2,790 per pair Estimated B&H Photo Video eBay
Same family: the Genelec G One (smaller bookshelf, estimated 4.4/5), the Genelec G Two (smaller bookshelf, rated 4.3/5), the Genelec G Three (smaller bookshelf, estimated 4.5/5) and the Genelec G Five (larger bookshelf, ranked higher, estimated 4.3/5).
Pros: A home speaker built on the drivers and waveguide of the Genelec 8040B studio monitor: a 6.5” woofer and 0.75” metal-dome tweeter in a die-cast aluminum cabinet, each with its own 90W amplifier. Bass reaches 48Hz (±2.5dB) and 41Hz (-6dB), and it plays to 105dB short-term, enough to fill a medium living room without a subwoofer. RCA and balanced XLR inputs and rear tone switches handle consumer and pro sources and different placements.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Genelec 8040B it is based on. There is no GLM room calibration or digital input, and at nearly 10kg each it needs sturdy stands or shelves.
