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.

Palmer STUDIMON 5: $350 per pair Thomann eBay
Pros: The available third-party measurements predict 3.48 standalone and 6.37 with an ideal subwoofer. Balanced inputs and a conventional compact monitor cabinet make it straightforward to use with studio equipment. The broad response trend is approximately level rather than strongly bright or dark.
Cons: The trace spans 4.0dB from 300Hz to 5kHz and estimates -3dB bass around 80Hz, with local irregularities despite the level overall trend. There are no room-EQ controls to address broad placement errors, and the available score does not establish clean output.
