Short answer: the Dayton Audio M4 for better sound quality, the Edifier R1280T for the lower price. The Dayton Audio M4 ranks #28 of 64 powered bookshelf speakers at $249.98. The Edifier R1280T ranks #36 at $129.97, $120.01 cheaper.
What the Edifier R1280T offers: ASR’s Klippel-based measurements found the woofer handled a demanding bass-heavy track without bottoming out or audible distortion, and distortion stayed low and inaudible at a normal 86dB SPL listening level. Built-in remote and bass/treble tone controls, no separate preamp needed. Watch for: On-axis response is jagged rather than neutral, with a woofer resonance around 5kHz and a tweeter peak near 10kHz that also show up in the directivity data, making off-axis/room response uneven too - the reviewer’s raw impression was “a bit bass heavy and after a track or two, somewhat bright,” and he recommends EQ correction. Vertical listening window is narrow, so the tweeter needs to be angled toward the ears. Pushed to 96dB SPL the tonal balance shifts noticeably, a sign of compression starting even though the driver doesn’t audibly break up.
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.
