Short answer: the Kali LP-UNF for better sound quality, the Edifier R1700BT for the lower price. The Kali LP-UNF ranks #8 of 58 powered bookshelf speakers at $349. The Edifier R1700BT ranks #48 at $186.99, $162.01 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 Edifier R1700BT offers: Watch for: more V shaped, not quite as neutral sounding as the Edifier MR4
Buy the Kali LP-UNF if sound quality matters more than the price. Buy the Edifier R1700BT if the price matters more than sound quality.
If sound quality matters at all to you, skip the Edifier R1700BT. It ranks near the bottom of the 58 powered bookshelf speakers, so look higher up the list instead.
