Short answer: the Genelec 8020D on measured sound quality, the Dayton Audio M4 on price. The Genelec 8020D ranks #12 of 100 powered bookshelf speakers, rated 4.4/5, at $1,390. The Dayton Audio M4 ranks #52, rated 3.8/5, at $249.98, $1,140.02 cheaper.
The Genelec 8020D is the better-sounding, deeper-bass pick. A compact waveguided monitor with balanced XLR input and placement filters, well suited to a small studio desk. Its bass reaches about 56Hz before falling 3dB, against 121Hz for the Dayton Audio M4. The tradeoff: Small size limits deep-bass reach and headroom.
What the Dayton Audio M4 does well: A compact powered pair with a subwoofer output, useful source connections and a solid cabinet. It keeps a wired aux input, which the Genelec 8020D lacks. The tradeoff: Existing listening and output notes describe limited bass, a balance that changes with distance, and distortion rising above roughly 93dB.

Genelec 8020D: $1,390 per pair B&H Photo Video eBay
Same family: the Genelec 8010A (smaller bookshelf, rated 4.5/5), the Genelec 8030C (larger bookshelf, ranked higher, rated 4.6/5), the Genelec 8040B (larger bookshelf, rated 4.3/5) and the Genelec 8050B (larger bookshelf, rated 4.4/5).
Pros: A compact waveguided monitor with balanced XLR input and placement filters, well suited to a small studio desk. Klippel measurements show a flat, well-behaved on-axis response from about 60Hz to 10kHz, with listening-window and early-reflection curves tracking closely, a sign of well-controlled directivity. Measured bass extension of 56Hz (-3dB).
Cons: Small size limits deep-bass reach and headroom. It lacks the GLM calibration of the SAM models, and the price is substantial for a compact analog-input monitor. Sound power starts rolling off around 500Hz to 1kHz as the small drivers begin to beam.

Dayton Audio M4: $249.98 per pair Parts Express eBay
Pros: A compact powered pair with a subwoofer output, useful source connections and a solid cabinet. The existing review describes reasonable linearity for the price and a subdued upper treble that avoids an aggressively bright presentation. It is best considered for a close desktop setup. Measured bass extension of 121Hz (-3dB).
Cons: Existing listening and output notes describe limited bass, a balance that changes with distance, and distortion rising above roughly 93dB. The soft treble is a tonal preference, not evidence of reference neutrality; a subwoofer does not establish greater midrange headroom.
