Short answer: the Edifier R1700BT. It ranks #49 of 60 powered bookshelf speakers by sound quality at $186.99; the Kali Audio IN-UNF ranks #51 and costs $699, so there is not much of a tradeoff to weigh.
What the Kali Audio IN-UNF offers: Ingenious ultra-nearfield system: a desk-mounted bass module uses two opposed 4.5-inch woofers below 280Hz, while the satellites use time-aligned 4-inch/1-inch coincident drivers. It is specifically engineered around the desk and, set up to Kali’s supplied placement template, sounded much better than it initially did to Erin; his moving-mic measurement at arm’s length closely matched the system’s predicted response. DSP provides placement, boundary and tonal trims, while USB-C, optical, 3.5mm and balanced TRS inputs cover desktop and studio sources. The round satellite enclosure avoids conventional baffle-edge diffraction, and the coaxial satellites image best aimed directly at the listener. Watch for: This is a very specialized system rather than a general desktop-speaker recommendation. The sizeable bass module must stay on the desk and prescribed satellite spacing can conflict with dual or ultrawide monitors; Erin and Joe N Tell both preferred Kali’s LP-6/IN-series alternatives for their own desks. A bump around 100-130Hz and a possible 1.2kHz diffraction feature appeared in Erin’s exploratory anechoic data, but he explicitly cautioned that those measurements do not replicate the required desk geometry. Bass falls away around 40-50Hz despite the separate bass unit. Erin did not publish comparable anechoic F3/F10, sensitivity or impedance figures because the system is designed around a fixed desk arrangement.
What the Edifier R1700BT offers: Rated 3.5 in the SpeakerRanking database. Watch for: more V shaped, not quite as neutral sounding as the Edifier MR4
Buy the Edifier R1700BT. It ranks higher for sound quality than the Kali Audio IN-UNF and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip both of these and look higher up the 60 powered bookshelf speakers instead.
