Short answer: the Pioneer DJ VM-50. It ranks #44 of 64 powered bookshelf speakers by sound quality at $169; the Audioengine HD4 ranks #54 and costs $429, so there is not much of a tradeoff to weigh.
What the Pioneer DJ VM-50 offers: Compact active monitor with 96kHz DSP, 4mm aluminum front baffle, 5.25-inch aramid woofer and constant-directivity horn. Erin measured F3 at 61Hz, low distortion at 86 and 96dB, almost no long-term compression above 50Hz and only roughly quarter-decibel dynamic nonlinearity. Four-position low- and high-EQ controls yield 16 useful voicings, while balanced TRS/XLR and RCA inputs suit studio and consumer sources. Watch for: The default axial response is not reference-flat and the upper-mid/treble directivity behavior varies with angle; correct EQ-switch selection and listening geometry matter. Bass does not reach 50Hz at reference level despite its pleasing punch, making a subwoofer useful. Output is appropriate for nearfield use rather than home-theater distance. As an internally amplified monitor, passive impedance and sensitivity measurements are not applicable.
What the Audioengine HD4 offers: Rated 3.3 in the SpeakerRanking database. Watch for: Not a great sounding speaker for the high price.
Buy the Pioneer DJ VM-50. It ranks higher for sound quality than the Audioengine HD4 and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the Audioengine HD4. It ranks near the bottom of the 64 powered bookshelf speakers, so look higher up the list instead.
