Short answer: the Kali LP-UNF. It ranks #8 of 60 powered bookshelf speakers by sound quality at $349; the NHT Pro M-00 ranks #60 and costs $498, 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 NHT Pro M-00 offers: Cast aluminum-zinc alloy enclosure doubles as a heatsink for the built-in discrete Class AB amplifier, and both RCA and XLR/TRS inputs are provided with a near-field/far-field voicing switch. Watch for: Amir identified a critical flaw: a sudden suck-out in the upper bass frequencies that affects many commonly-used notes. Treble peaks on-axis, and vertical-axis performance is particularly problematic. In-room response turns notably bright in rooms with absorptive surfaces. Comparing directly to the JBL 305P Mark II, Amir found the NHT sounded “dead and bright” while the JBL was “balanced” with “rich and warm detail,” concluding, “I would not remotely use the NHT M-00 relative to JBL 305P Mark ii. The difference in overall fidelity and pleasantness is immense.” Long discontinued; not recommended even on the used market.
Buy the Kali LP-UNF. It ranks higher for sound quality than the NHT Pro M-00 and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the NHT Pro M-00. It ranks near the bottom of the 60 powered bookshelf speakers, so look higher up the list instead.
