Short answer: the Kali Audio SM-5 if sound quality matters most, the Audioengine HD4 if price matters most. The Kali Audio SM-5 ranks #25 of 100 powered bookshelf speakers, rated 4.2/5, at $2,998. The Audioengine HD4 ranks #83, rated 3.2/5, at $429, $2,569 cheaper.
The Kali Audio SM-5 is the better-sounding pick. Erin’s measurements show bass reaching -3dB around 43Hz and a 2.8dB midrange response span. It has an adjustable EQ, which the Audioengine HD4 lacks. The catch: Scores of 5.18 standalone and 7.13 with an ideal subwoofer are good but below the leading reference monitors, so its advanced driver layout does not justify a near-top ranking by itself.
The case for the Audioengine HD4: Compact powered cabinets, analog input options and RCA output can simplify a desktop stereo system. It keeps a wired aux input, which the Kali Audio SM-5 lacks. The tradeoff: The compact cabinets suit close desktop listening rather than a large-room system.
Buy the Kali Audio SM-5 when sound quality outweighs the price for you, and the Audioengine HD4 when the price outweighs sound quality instead.

Kali Audio SM-5: $2,998 per pair B&H Photo Video eBay
Pros: Erin’s measurements show bass reaching -3dB around 43Hz and a 2.8dB midrange response span. The coaxial mid/tweeter and large waveguide give useful consistency horizontally and vertically, reducing sensitivity to listening height. Built-in per-speaker DSP and mounting options make placement flexible. Existing testing reports low midrange distortion at 96dB. Measured bass extension of 45Hz (-3dB).
Cons: Scores of 5.18 standalone and 7.13 with an ideal subwoofer are good but below the leading reference monitors, so its advanced driver layout does not justify a near-top ranking by itself. A small upper-midrange irregularity remains. The five-inch woofer and limiter constrain loud bass; the review places compression onset roughly in the 96-102dB/1m region.

Audioengine HD4: $429.00 per pair Amazon eBay
Same family: the Audioengine HD3 (smaller bookshelf, rated 3.2/5) and the Audioengine HD6 (larger bookshelf, ranked higher, rated 3.3/5).
Pros: Compact powered cabinets, analog input options and RCA output can simplify a desktop stereo system. Its modest footprint is useful where larger studio monitors are impractical.
Cons: The compact cabinets suit close desktop listening rather than a large-room system. A separate subwoofer adds cost and space if deeper bass is a priority.
