Short answer: the Onkyo GX-30ARC. It ranks #39 of 67 powered bookshelf speakers by sound quality, rated 3.7/5, at $349; the Adam Audio A4V ranks #43, rated 3.6/5, and costs $599.99, so there is little reason to consider the other one.
Why pick the Adam Audio A4V: Compact monitor with onboard DSP, placement controls and room-correction integration. The tradeoff: A small average-deviation figure hides a major localized response irregularity: the selected measurement spans 10.8dB from 300Hz to 5kHz, and listening-window narrow-band deviation is 0.547.
Why pick the Onkyo GX-30ARC: HDMI ARC, USB-C, optical and analog inputs make it a convenient compact system for a desk or TV. The catch: The response rises toward the treble by about 0.48dB per octave.
Buy the Onkyo GX-30ARC. It is rated higher for sound quality than the Adam Audio A4V and costs less, so there is no real case for the other one.

The Two Speakers In Full
Adam Audio A4V: $1,199.98 per pair B&H Photo Video eBay
Pros: Compact monitor with onboard DSP, placement controls and room-correction integration. ASR’s Klippel data gives a -3dB point around 59Hz and preference scores of 3.92 standalone and 6.33 with an ideal subwoofer. Its adjustment facilities are useful when placement or tonal correction is needed.
Cons: A small average-deviation figure hides a major localized response irregularity: the selected measurement spans 10.8dB from 300Hz to 5kHz, and listening-window narrow-band deviation is 0.547. The native response should therefore not be called smoothly neutral. Correction potential is not the same as stock performance, and analog audio inputs mean a separate interface is needed for USB sources.

Onkyo GX-30ARC: $349 per pair Onkyo eBay
Pros: HDMI ARC, USB-C, optical and analog inputs make it a convenient compact system for a desk or TV. Erin’s Klippel data gives a 3.69 standalone preference score and 6.42 with an ideal subwoofer. The midrange response spans 3.8dB, offering usable but not reference-level tonal performance.
Cons: The response rises toward the treble by about 0.48dB per octave. Bass reaches -3dB around 74Hz, not the lower LFX value used inside the preference model. Vertical listening position affects crossover balance. Its extensive connectivity does not compensate for response irregularities, and the published tonal data alone does not establish maximum clean output.
