Short answer: the Genelec 8020D for better sound quality, the Audioengine HD4 for the lower price. The Genelec 8020D ranks #6 of 64 powered bookshelf speakers at $1100. The Audioengine HD4 ranks #54 at $429, $671 cheaper.
What the Genelec 8020D offers: Klippel-based spinorama measurements show a flat, well-behaved on-axis response from about 60Hz to 10kHz, with listening-window and early-reflections curves tracking closely together - a sign of well-controlled directivity. Horizontal directivity holds tight out to about ±30 degrees before starting to narrow. Applying EQ correction visibly closes the gap between the on-axis and predicted in-room curves, raising the calculated on-axis preference score from 5.4 to 6.4 and the in-room score from 5.6 to 6.6 - a straightforward, worthwhile tuning target for anyone using it with room correction. Watch for: Sound power rolls off starting around 500Hz-1kHz as the small 4.1” woofer/tweeter pair begins to beam, a typical trait of small nearfield monitors at this price. Off-axis response (measured out to 90 degrees) narrows noticeably above 1kHz, so off-center listening loses top-end energy. High price for the driver size.
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 Genelec 8020D if sound quality matters more than the price. Buy the Audioengine HD4 if the price matters more than sound quality.
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.
