Short answer: the KEF LSX II LT. It ranks #27 of 58 powered bookshelf speakers by sound quality at $600; the Kali Audio IN-UNF ranks #50 and costs $699, so there is not much of a tradeoff to weigh.
What the KEF LSX II LT offers: Coaxial (Uni-Q-style) driver keeps the tweeter centered in the midrange, giving wide and consistent dispersion both horizontally and vertically (about ±60° each) - a wide sweet spot for multiple seats or positions. The KEF Connect app provides genuinely useful DSP control: desk/wall boundary compensation, adjustable bass contour (standard/less/extra), treble trim, and subwoofer integration, letting you tune the sound to wherever it’s placed. Distortion at a moderate 86dB looks good for the speaker’s compact size. Tonal profile stays consistent from 0° to 30° off-axis, so side-seat listeners hear essentially the same balance as someone centered. Extensive connectivity for its size: HDMI, USB, optical, sub output, plus Wi-Fi/Bluetooth. Clearly outperformed the reviewer’s soundbars, including ones bundled with their own subwoofers, as a TV audio replacement. Watch for: Small drivers mean it’s SPL-limited: bass compression kicks in around 88-92dB/1m per speaker, and multitone distortion crosses the reviewer’s 3% threshold around 96dB - not intended for loud or large-room duty. F3 of 55Hz and F10 of 46Hz mean it loses much of its bass by around 50Hz; a subwoofer (controllable through the same app) is needed for real low end. Diffraction dips appear around 4-5kHz and again near 8kHz, likely tied to the tweeter housing or surround, giving a mild reduction in treble attack and sibilance. A possible port or enclosure resonance shows up around 800Hz in the rear-radiation measurements, though the reviewer wasn’t certain of the exact cause or whether it’s audible. No analog input on this LT variant, so a turntable can’t be connected directly - only the pricier standard LSX II model includes one.
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.
Buy the KEF LSX II LT. 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 the Kali Audio IN-UNF. It ranks near the bottom of the 58 powered bookshelf speakers, so look higher up the list instead.
