Short answer: the Genelec 8331A for better sound quality, the Edifier MR4 for the lower price. The Genelec 8331A ranks #1 of 64 powered bookshelf speakers at $5750. The Edifier MR4 ranks #31 at $129.97, $5620.03 cheaper.
What the Edifier MR4 offers: More balanced than the R1280DB. The value king. Impressively deep, flat bass down to 70Hz for such a small speaker, and its waveguide gives it unusually wide, consistent horizontal directivity for the price. Balanced XLR/TRS inputs are rare this cheap. Watch for: No Bluetooth unlike other Edifier models. Distortion climbs sharply above 86dB SPL, breaking into audible squealing near 96dB, and there’s a dip in the lower treble that needs a bit of EQ or the rear HF control to smooth out. Playback volume is limited with bass-heavy material - pushing it loud brings audible clicking/static.
What the Genelec 8331A offers: A true compact point source: the coaxial mid/tweeter and acoustically concealed opposed woofers produce exceptionally uniform directivity, superb nearfield summation and pinpoint imaging. Erin measured F3 at 49Hz and F10 at 39Hz, heard useful 40Hz in-room extension, and reached 100dB at 3m before protection activated. Response is highly neutral, distortion is low, and GLM provides calibrated level, delay and room-response correction. The die-cast aluminum waveguide/enclosure is both structurally inert and nearly diffraction-free. Watch for: At $4,500/pair it is expensive for a monitor whose protection circuit mutes near its limit rather than allowing short-term overload; larger rooms and bass-heavy playback still benefit from a subwoofer. GLM calibration requires separate network hardware, and connectivity is studio-centric—analog/AES XLR with no consumer streaming. The compact dual racetrack woofers cannot match larger Genelec Ones for deep-bass headroom, and passive sensitivity is not applicable because all filtering and amplification are internal.
Buy the Edifier MR4 if the price matters more than sound quality. Buy the Genelec 8331A if sound quality matters more than the price.
