Short answer: the Kali LP-UNF for better sound quality, the Neumi BS5P-ARC for the lower price. The Kali LP-UNF ranks #8 of 64 powered bookshelf speakers at $349. The Neumi BS5P-ARC ranks #61 at $219.99, $129.01 cheaper.
What the Kali LP-UNF offers: 1” dome tweeter on a waveguide crossed unusually low at 1.9kHz to a 4.5” ported midwoofer, giving wide vertical dispersion (about ±30-40° off the tweeter/mid reference axis) for a two-way design - well beyond the typical ±10-15°. Extensive dip-switch tuning covers desk vs. free-standing placement, near-wall (<0.5m) compensation, and ±2dB treble/bass adjustment. Distortion stays below 3% at 86dB; the reviewer calls it the best-measuring powered desktop monitor he’s tested, ahead of competitors like the PreSonus Eris E3.5 2nd Gen and Fosi SP3, which he describes as having one-note bass and roughly a 7dB midrange suckout. USB-C, RCA, TRS, and Bluetooth inputs; the secondary speaker is powered through a link cable from the primary unit rather than needing its own separate power connection. At $300/pair, called a no-brainer recommendation for a compact desktop monitor. Watch for: F3 of 54Hz and F10 of 39Hz mean bass rolls off quickly below about 40Hz, bottoming out around 50Hz in-room. No dedicated subwoofer output - pairing with an outboard sub (routing its own crossover back through the mains) is the only way to extend bass further. A built-in limiter caps real-world maximum output around 91dB/1m per speaker, about 5dB below the 96dB target used in compression testing, and distortion climbs past 3% beyond that point. Designed strictly for near-field use (about 0.8m recommended listening distance), not for filling a larger room at volume.
What the Neumi BS5P-ARC offers: Adds an HDMI ARC input over Neumi’s standard BS5P, plus USB-C, optical and coaxial digital inputs, useful as a simple TV soundbar alternative. Watch for: Erin’s Audio Corner measured a rough response: on-axis deviation of 0.617dB, on-axis smoothness of just 0.167, and a mild +0.08dB per octave upward tilt, with predicted in-room smoothness of just 0.26. A -3dB point of 112.8Hz and a Harman in-room extension estimate of just 79Hz mean very little real bass extension without a subwoofer.
Buy the Kali LP-UNF if sound quality matters more than the price. Buy the Neumi BS5P-ARC if the price matters more than sound quality.
If sound quality matters at all to you, skip the Neumi BS5P-ARC. It ranks near the bottom of the 64 powered bookshelf speakers, so look higher up the list instead.
