Short answer: the Kali LP-UNF for the higher ranking, the Edifier R1280DB for the lower price. The Kali LP-UNF ranks #5 of 24 powered bookshelf speakers at $349. The Edifier R1280DB ranks #23 at $189.99, $159.01 cheaper.
What the Edifier R1280DB gets right: Excellent bass output and power handling for the price, not bottoming out or distorting even played loud. The tradeoff: Not quite as neutral sounding as the Edifier MR4.
On the Kali LP-UNF side: 1” dome tweeter on a waveguide crossed unusually low at 1.9kHz to a 4.5” ported midwoofer. The tradeoff: F3 of 54Hz and F10 of 39Hz mean bass rolls off quickly below about 40Hz, bottoming out around 50Hz in-room.
Buy the Edifier R1280DB if the price matters more than the ranking. Buy the Kali LP-UNF if the ranking matters more than the price.

Kali LP-UNF: $349.00 Amazon
Pros: 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.
Cons: 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.
