Short answer: the Sovox MiniMax3. It ranks #9 of 24 powered bookshelf speakers by sound quality, rated 3.7/5, at $650. The Kanto YU4 ranks #14, rated 3.3/5, at $479.99, $170.01 cheaper, which does not close the gap in sound quality.
What the Sovox MiniMax3 does well: A coaxial midrange and tweeter give a wide, even sweet spot, and a listening-window smoothness of 0.78 lifts it to a 6.48 preference score with an ideal subwoofer, so tonal balance holds as you shift around a desk. The catch: Output tops out around 86dB, with heavy compression and very high distortion as it gets there, so it only suits nearfield listening at modest volume.
What the Kanto YU4 does well: Phono, optical and Bluetooth inputs, remote control and a subwoofer output make it convenient for a compact multi-source system. Watch for: Standalone preference is only 2.89, with a -3dB point around 86Hz and a 4.2dB midrange response span.
Buy the Sovox MiniMax3. It is rated higher for sound quality, and the $170.01 saving on the Kanto YU4 is not enough to make up the difference.

The Two Speakers In Full
Sovox MiniMax3: $650 per pair Sovox eBay
Pros: A coaxial midrange and tweeter give a wide, even sweet spot, and a listening-window smoothness of 0.78 lifts it to a 6.48 preference score with an ideal subwoofer, so tonal balance holds as you shift around a desk. The 3.5-inch woofer and 5-inch passive radiator reach 66Hz at -3dB and about 53Hz at -12dB, deeper than most speakers this small. The unibody aluminum enclosure is solid and only 195mm tall, and Free, Desk, Wall and Desk & Wall presets plus treble and bass trims adapt it to its placement. Measured bass extension of 66Hz (-3dB).
Cons: Output tops out around 86dB, with heavy compression and very high distortion as it gets there, so it only suits nearfield listening at modest volume. Treble rises on axis (+0.35dB per octave), which holds its standalone preference score to 3.84; toeing it about 10 degrees away from your ears smooths the top end. Bass falls away quickly below 60Hz and there is no subwoofer output, and inputs are limited to balanced XLR and RCA.

Kanto YU4: $479.99 per pair Kanto eBay
Pros: Phono, optical and Bluetooth inputs, remote control and a subwoofer output make it convenient for a compact multi-source system. ASR’s measured horizontal coverage is broad enough for some freedom of seating position. The ideal-subwoofer preference score of 5.83 indicates that bass support would materially improve its usefulness.
Cons: Standalone preference is only 2.89, with a -3dB point around 86Hz and a 4.2dB midrange response span. Response irregularities remain even after bass extension is removed from the comparison, so a subwoofer alone will not make it neutral. Sensitivity measured at an arbitrary powered-speaker gain setting is not a reliable basis for judging efficiency or maximum volume.
