Short answer: the Pioneer DJ VM-50. It ranks #34 of 105 powered bookshelf speakers by sound quality, rated 4.0/5, at $418; the Audioengine HD4 ranks #86, rated 3.2/5, and costs $429, so there is not much of a tradeoff to weigh.
The Pioneer DJ VM-50 is the better-sounding pick. Erin’s Klippel measurements give scores of 4.64 standalone and 7.00 with an ideal subwoofer, with a -3dB point around 60Hz. The tradeoff: The default response spans 3.5dB from 300Hz to 5kHz, and the upper-midrange/treble balance varies with angle.
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 Pioneer DJ VM-50 lacks. Watch for: The compact cabinets suit close desktop listening rather than a large-room system.
Buy the Pioneer DJ VM-50. It is rated higher for sound quality than the Audioengine HD4 and costs less, so only choose the other one for a particular feature it does better.

Pioneer DJ VM-50: $418 per pair Amazon B&H Photo Video eBay
Same family: the Pioneer DJ VM-70 (larger bookshelf, estimated 4/5) and the Pioneer DJ VM-80 (larger bookshelf, estimated 4/5).
Pros: Erin’s Klippel measurements give scores of 4.64 standalone and 7.00 with an ideal subwoofer, with a -3dB point around 60Hz. The existing review reports low distortion and little sustained compression, supporting practical clean playback beyond what the tonal score alone captures. Separate bass and treble voicings and balanced inputs make adjustment straightforward. Measured bass extension of 61Hz (-3dB).
Cons: The default response spans 3.5dB from 300Hz to 5kHz, and the upper-midrange/treble balance varies with angle. EQ-switch selection and aiming therefore matter. Bass below about 50Hz is reduced, so it is not a full-range substitute for a monitor-and-subwoofer system. Its output evidence supports nearfield use, not unrestricted home-theater levels.

Audioengine HD4: $429.00 per pair Amazon eBay
Same family: the Audioengine HD3 (smaller bookshelf, rated 3.2/5), the Audioengine HD6 (larger bookshelf, ranked higher, rated 3.3/5) and the Audioengine HD5 (larger bookshelf, ranked lower, estimated 3.2/5).
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.
