Short answer: the HiVi Swan X3. It ranks #7 of 24 powered bookshelf speakers by sound quality, rated 3.9/5, at $249; the Monacor SOUND-4BT ranks #13, rated 3.3/5, and costs $310, so there is not much of a tradeoff to weigh.
What the HiVi Swan X3 does well: ASR’s Spinorama data predicts 4.04 standalone and 7.03 with an ideal subwoofer, placing its bass-normalized tonal performance ahead of several similarly small budget monitors. The tradeoff: Not a flat reference monitor: the response spans 5.0dB from 300Hz to 5kHz and trends upward toward the treble.
Why pick the Monacor SOUND-4BT: The available measurements suggest useful bass for its size, with a -3dB point around 61Hz, and a fairly small 2.8dB response span from 300Hz to 5kHz. The tradeoff: Predicted in-room response remains uneven despite the modest midrange span.
Buy the HiVi Swan X3. It is rated higher for sound quality than the Monacor SOUND-4BT and costs less, which settles it without a real tradeoff to make.

HiVi Swan X3: $249 per pair eBay
Pros: ASR’s Spinorama data predicts 4.04 standalone and 7.03 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.
Cons: 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.

Monacor SOUND-4BT: $310 per pair LTT Versand eBay
Pros: The available measurements suggest useful bass for its size, with a -3dB point around 61Hz, and a fairly small 2.8dB response span from 300Hz to 5kHz. Optical and analog inputs, Bluetooth, remote control and a subwoofer output make it versatile for a compact stereo setup.
Cons: Predicted in-room response remains uneven despite the modest midrange span. A subwoofer can add bass reach but does not correct the remaining tonal variations.
