Short answer: the Kali LP-UNF. It ranks #44 of 100 powered bookshelf speakers by sound quality (rated 3.9/5) at $349 and is still sold new; the NHT Pro M-00 ranks #98 (rated 1.7/5) and is discontinued, so it is only an option used.
The Kali LP-UNF is the better-sounding, deeper-bass choice. A practical compact desktop system with USB-C, analog inputs and Bluetooth, plus extensive placement switches. Its bass reaches about 54Hz before falling 3dB, against 83.3Hz for the NHT Pro M-00. The catch: The 2.9dB midrange span masks local response ripples; listening-window narrow-band deviation of 0.467 is behind the best monitors.
What the NHT Pro M-00 does well: A sturdy metal enclosure, analog studio/consumer connections and selectable nearfield/farfield voicing give it practical features as an older powered monitor. The tradeoff: The review identifies a pronounced upper-bass cancellation, treble peaks and problematic vertical response, and strongly prefers the JBL 305P MKII in direct listening.
Buy the Kali LP-UNF. It is rated higher for sound quality; the NHT Pro M-00 is no longer sold new.

Kali LP-UNF: $349.00 per pair Amazon eBay
Same family: the Kali Audio LP-6 V2 (smaller bookshelf, rated 4.4/5) and the Kali Audio LP-8 V2 (smaller bookshelf, rated 4.1/5).
Pros: A practical compact desktop system with USB-C, analog inputs and Bluetooth, plus extensive placement switches. Erin’s Klippel data gives -3dB bass around 54Hz and scores of 4.60 standalone and 6.67 with an ideal subwoofer. The low crossover and waveguide provide useful freedom of listening height for a two-way design, and moderate-level distortion is well controlled in the review. The 1.9kHz crossover gives vertical coverage of about ±30 to 40°, well beyond the typical ±10 to 15° of a two-way. Measured bass extension of 54Hz (-3dB), with a measured sensitivity of 88.1dB.
Cons: The 2.9dB midrange span masks local response ripples; listening-window narrow-band deviation of 0.467 is behind the best monitors. The review finds limiting around 91dB/1m per speaker. No dedicated subwoofer output means integration requires suitable external routing or bass management. Its strength is affordable close listening, not top-tier tonal accuracy or high-output room playback.
