Short answer: the Audioengine HD3 for better sound quality, the Kali LP-UNF for the lower price. The Audioengine HD3 ranks #15 of 22 powered bookshelf speakers at $359. The Kali LP-UNF ranks #32 at $349, $10 cheaper.
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 Audioengine HD3 when sound quality outweighs the price for you, and the Kali LP-UNF when the price outweighs sound quality instead.

Audioengine HD3: $359.00 Amazon eBay
Pros: A compact desktop stereo option when cabinet size is a priority.
Cons: Limited bass makes a subwoofer useful for fuller music reproduction. Its compact format is better suited to close listening than filling a large room.

Kali LP-UNF: $349.00 Amazon eBay
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 3.68 standalone and 5.76 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.
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.
