Short answer: the Onkyo GX-30ARC. It ranks #55 of 100 powered bookshelf speakers by sound quality, rated 3.7/5, at $249; the KRK Classic 5 ranks #72, rated 3.4/5, and costs $319.99, so there is not much of a tradeoff to weigh.
Why pick the KRK Classic 5: ASR’s Klippel data gives -3dB bass around 60Hz and a 5.99 preference score with an ideal subwoofer. Watch for: The native standalone score is 3.47 and the midrange span is a large 6.5dB.
The Onkyo GX-30ARC is the better-sounding pick. HDMI ARC, USB-C, optical and analog inputs make it a convenient compact system for a desk or TV. It keeps a wired aux input, which the KRK Classic 5 lacks. 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 KRK Classic 5 and costs less, which makes it the one to get unless you need something the other one does better.

The Two Speakers In Full
KRK Classic 5: $319.99 per pair Amazon eBay
Pros: ASR’s Klippel data gives -3dB bass around 60Hz and a 5.99 preference score with an ideal subwoofer. Broad tonal correction can improve it, so it may be useful to someone willing to measure and EQ a basic studio setup. Measured bass extension of 60.1Hz (-3dB).
Cons: The native standalone score is 3.47 and the midrange span is a large 6.5dB. Excess treble and crossover/directivity errors keep it from being neutral out of the box, while low-bass distortion limits loud playback. Modeled EQ scores are not stock performance and do not demonstrate corrected distortion or dispersion.

Onkyo GX-30ARC: $249.00 per pair Amazon B&H Photo Video 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.
