Short answer: the Genelec 8030C for better sound quality, the Dayton Audio M4 for the lower price. The Genelec 8030C ranks #3 of 64 powered bookshelf speakers at $1590. The Dayton Audio M4 ranks #28 at $249.98, $1340.02 cheaper.
What the Genelec 8030C offers: CEA2034 spinorama shows a near-flat on-axis response with smooth directivity - “very nice overall.” Predicted in-room response is excellent aside from one minor dip. Reasonably wide horizontal beamwidth of about ±60 degrees that doesn’t narrow even above 10kHz. At 106dB SPL/1m, bass distortion measures much lower than a comparable passive speaker-plus-amplifier combination (Revel M106) tested the same way. Compression is purely instantaneous/amplitude-related rather than thermal, with max SPL before compression reaching 111dB SPL at 200Hz (96dB plus 15dB of headroom). The reviewer found it immediately musical, with reference tracks “translating” beautifully out of the box, and EQ correction of its one measured flaw improved detail with no downsides. Overall conclusion: excellent value, a rare combination of measured accuracy and genuinely engaging sound. Watch for: A minor but measurable dip between 2-3kHz shows up in both on- and off-axis measurements. Vertical directivity varies significantly with frequency, so listening height needs to stay right at the tweeter/ear axis for accurate tonal balance. Distortion at 106dB SPL/1m is elevated in the 500Hz-2kHz range compared to the Revel M106 comparison, even though bass distortion is much better. Compression headroom drops substantially at low frequencies - only about 105dB SPL max at 50Hz (a 0.5dB compression point) versus 111dB SPL at 200Hz, roughly a 6dB difference. As a near-field monitor, it has genuinely limited headroom in the deep bass - the reviewer noted severe distortion on deep-bass-heavy tracks at anything beyond modest listening levels.
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 8030C if sound quality matters more than the price. Buy the Dayton Audio M4 if the price matters more than sound quality.
