Short answer: the Adam Audio D3v on measured sound quality, the HiVi Swan X3 on price. The Adam Audio D3v ranks #3 of 23 powered bookshelf speakers at $339.99. The HiVi Swan X3 ranks #7 at $249, $90.99 cheaper.
What the Adam Audio D3v offers: Excellent midrange linearity for a tiny desktop speaker: Erin’s Klippel data spans just 1.7dB from 300Hz to 5kHz. Side passive radiators help bass reach -3dB at about 51Hz, substantially deeper than the Genelec 8010A or Audio Smile LBM. Predicted preference scores of 4.47 standalone and 6.70 with an ideal subwoofer support it as a particularly useful compact system without a sub. USB-C, analog inputs and placement filters simplify desk setup. Watch for: A rising upper-frequency balance and vertical crossover interference keep it from being uniformly neutral at every angle; aim the tweeters toward ear height. The limiter reduces bass and midrange output as volume rises, with the existing review’s compression tests putting usable maximum output around 89-90dB at 1m. Deep bass at moderate volume should not be confused with high output capability.
What the HiVi Swan X3 offers: ASR’s Spinorama data predicts 3.13 standalone and 6.12 with an ideal subwoofer, placing its bass-normalized tonal performance ahead of several similarly small budget monitors. Listening-window narrow-band deviation is 0.420, lower than the MR3’s 0.538, indicating fewer local response irregularities by that measure. The compact coaxial layout is convenient for a small desktop system. Watch for: Not a flat reference monitor: the response spans 5.0dB from 300Hz to 5kHz and trends upward toward the treble. Bass reaches -3dB at about 79Hz, so a subwoofer remains important. Coaxial construction alone does not guarantee uniform dispersion, and the preference score does not establish distortion or maximum clean output.
Buy the Adam Audio D3v if sound quality is the priority over the price, or the HiVi Swan X3 if the price is the priority over sound quality.
