Short answer: the Dayton Audio M4. It ranks #38 of 67 powered bookshelf speakers by sound quality, rated 3.8/5, at $249.98; the Onkyo GX-30ARC ranks #39, rated 3.7/5, and costs $349, so there is not much of a tradeoff to weigh.
The case for 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.
Why pick the Dayton Audio M4: A compact powered pair with a subwoofer output, useful source connections and a solid cabinet. Watch for: Existing listening and output notes describe limited bass, a balance that changes with distance, and distortion rising above roughly 93dB.
Buy the Dayton Audio M4. It is rated higher for sound quality than the Onkyo GX-30ARC and costs less, so there is no real case for the other one.

The Two Speakers In Full
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.

Dayton Audio M4: $249.98 per pair Parts Express eBay
Pros: A compact powered pair with a subwoofer output, useful source connections and a solid cabinet. The existing review describes reasonable linearity for the price and a subdued upper treble that avoids an aggressively bright presentation. It is best considered for a close desktop setup. Measured bass extension of 121Hz (-3dB).
Cons: Existing listening and output notes describe limited bass, a balance that changes with distance, and distortion rising above roughly 93dB. The soft treble is a tonal preference, not evidence of reference neutrality; a subwoofer does not establish greater midrange headroom.
