Short answer: the Edifier MR4.5. It ranks #69 of 108 powered bookshelf speakers by sound quality, rated 3.6/5, at $199.99; the Kali Audio IN-UNF ranks #83, rated 3.3/5, and costs $699, so there is not much of a tradeoff to weigh.
The Edifier MR4.5 is the better-sounding choice. A desktop monitor pair with deep bass for its size, LDAC Bluetooth, balanced inputs, a headphone jack and app tuning. The tradeoff: The response is uneven, with a broad upper-bass bump around 120 to 150Hz, a presence dip of roughly 3dB around 2 to 3kHz and brighter treble above it (listening-window tilt +0.22dB per octave), which holds its preference score to about 3.9 on its own and 6.1 with an ideal subwoofer.
The Kali Audio IN-UNF is the deeper-bass pick. A desk system of small coaxial satellites and a bass module, with DSP placement controls and USB-C, optical and balanced inputs. Its bass reaches about 39Hz before falling 10dB, against 44Hz for the Edifier MR4.5. The catch: The intended desk geometry is part of the acoustic design.
Buy the Edifier MR4.5. It is rated higher for sound quality than the Kali Audio IN-UNF and costs less, so only choose the other one for a particular feature it does better.
