Short answer: the Adam Audio D3v. It ranks #3 of 8 powered bookshelf speakers at $349.99; the Audioengine HD3 ranks #4 and costs $359, so there is not much of a tradeoff to weigh.
The case for the Adam Audio D3v: Compact powered desktop monitor with passive radiators on the sides for extra bass extension. The catch: Built-in limiter chops off both low-frequency and midrange content as output increases - not intended for loud or far-field listening.
Buy the Adam Audio D3v if the ranking matters more than the price. Buy the Audioengine HD3 if the price matters more than the ranking.

The Two Speakers In Full
Adam Audio D3v: $349.99 Amazon
Pros: Compact powered desktop monitor with passive radiators on the sides for extra bass extension, designed specifically for near-field (about 1 meter) listening. Bass extends flat to about 50Hz before rolling off sharply. On-axis linearity holds within about ±2dB - notably better linearity than its similarly-priced rival, the Kali LP-UNF. USB-C plus analog inputs, with the secondary speaker powered through a cable from the primary unit so only one power outlet is needed. Adjustable back-panel settings compensate for desk, wall, corner, or stand placement. Distortion in the midrange is better controlled than the larger Kali LP-UNF at moderate output levels. Smaller footprint than similarly-priced alternatives, useful for tight desk space, while still a clear step up from cheap sub-$150 desktop speakers.
Cons: Built-in limiter chops off both low-frequency and midrange content as output increases - not intended for loud or far-field listening. Best output window is roughly 78-86dB based on multitone distortion testing; long-term compression testing puts effective maximum SPL around 89dB, and instantaneous compression around 90dB. A slight treble tip-up appears around 4-6kHz on-axis. Vertical listening window is tight, typical of compact two-way designs - needs to stay close to the tweeter axis. Narrower horizontal dispersion (about ±60°) and less vertical placement tolerance than the Kali LP-UNF (about ±70° horizontal). The Kali LP-UNF, at the same price, offers roughly 2dB more maximum output and a bit more bass boost, if either matters more than the compact size.
