Short answer: the KEF LSX II LT. It ranks #35 of 100 powered bookshelf speakers by sound quality, rated 4.0/5, at $549.99; the Kali Audio IN-UNF ranks #81, rated 3.3/5, and costs $699, so there is not much of a tradeoff to weigh.
The KEF LSX II LT is the better-sounding option. The coincident driver provides useful consistency across listening positions, and the app offers placement and subwoofer adjustments. The catch: The 3.4dB midrange response span and treble-region dips keep it below more neutral monitors.
The Kali Audio IN-UNF is the deeper-bass pick. A specialized ultra-nearfield system with coaxial satellites and an opposed-woofer bass module designed to sit on the desk. Its bass reaches about 39Hz before falling 10dB, against 46Hz for the KEF LSX II LT. It keeps a wired aux input, which the KEF LSX II LT lacks. The tradeoff: The intended desk geometry is part of the acoustic design.
Buy the KEF LSX II LT. 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.

KEF LSX II LT: $549.99 per pair Amazon eBay
Same family: the KEF LSX II (larger bookshelf, estimated 4.1/5), the KEF LS50 Wireless II (larger bookshelf, ranked higher, rated 4.3/5) and the KEF LS60 (floorstanding, rated 4.8/5).
Pros: The coincident driver provides useful consistency across listening positions, and the app offers placement and subwoofer adjustments. Erin’s measurements give preference scores of 4.81 standalone and 7.03 with an ideal subwoofer, with -3dB bass around 56Hz. HDMI and USB connectivity make it convenient for a small TV or desktop system. Horizontal and vertical dispersion both reach about ±60°, giving a broad sweet spot for more than one seat. Measured bass extension of 55Hz (-3dB), with a measured sensitivity of 84dB.
Cons: The 3.4dB midrange response span and treble-region dips keep it below more neutral monitors. The existing review finds bass compression around 88-92dB/1m and rising distortion at higher levels, so the small drivers suit close listening rather than a large room. This LT version has no analog input; a turntable cannot plug straight into it.

Kali Audio IN-UNF: $699 per pair Kali Audio eBay
Same family: the Kali Audio IN-5 (smaller bookshelf, ranked higher, rated 4.2/5) and the Kali Audio IN-8 V2 (smaller bookshelf, rated 4.4/5).
Pros: A specialized ultra-nearfield system with coaxial satellites and an opposed-woofer bass module designed to sit on the desk. Erin found it worked much better when positioned using Kali’s placement template, with useful agreement between the intended response and close-range moving-microphone measurements. DSP placement controls and varied inputs make it a thoughtful solution for the right desk.
Cons: The intended desk geometry is part of the acoustic design. The bass module and prescribed spacing occupy considerable desk space and may conflict with large monitors. It is not designed for arbitrary room placement.
