Short answer: the Genelec 8020D for better sound quality, the Dayton Audio M4 for the lower price. The Genelec 8020D ranks #6 of 64 powered bookshelf speakers at $1100. The Dayton Audio M4 ranks #28 at $249.98, $850.02 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 Dayton Audio M4 offers: Good build quality. Has a subwoofer output for extending the low end. Overall linearity is decent for the price. Avoids sibilance since it’s slightly recessed right in the harsh 4-8kHz region. Watch for: The amplifier is only in the left speaker, so it’s not separate amps in each unit. Bass doesn’t extend very deep, and unlike some rivals it doesn’t use DSP to boost the low end. Sounds noticeably different up close versus at a normal listening distance, with a softer treble near field and a more recessed upper midrange farther away. Limited output headroom - distortion rises sharply above about 93dB, so it’s better suited to near-field or desktop use than as a far-field living-room speaker.
Buy the Genelec 8020D if sound quality matters more than the price. Buy the Dayton Audio M4 if the price matters more than sound quality.
