Short answer: the Kali LP-UNF. It ranks #8 of 58 powered bookshelf speakers by sound quality at $349; the Audioengine A5+ Classic ranks #38 and costs $399, so there is not much of a tradeoff to weigh.
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 Audioengine A5+ Classic offers: CEA2034 spinorama shows a reasonably flat response outside of the upper bass. Internal Class AB amplification (50W RMS, 75W peak) with a linear power supply drives a 5” Kevlar woofer and 0.75” tweeter. Watch for: A valley in the upper bass (200-400Hz) recesses that range, and a distortion peak shows up around 800-900Hz even at 86dB SPL. Off-axis response doesn’t track the on-axis curve well through the crossover, suggesting the waveguide isn’t fully optimized. Resonances appear at 900Hz and 4.4kHz.
Buy the Kali LP-UNF. It ranks higher for sound quality than the Audioengine A5+ Classic and costs less, so there is no real case for the other one.
