Short answer: the Sovox MiniMax3. It ranks #9 of 24 powered bookshelf speakers by sound quality, rated 3.7/5, at $650. The Monacor SOUND-4BT ranks #13, rated 3.3/5, at $310, $340 cheaper, not enough of a saving to outweigh the sound-quality gap.
Why pick the Sovox MiniMax3: A coaxial midrange and tweeter give a wide, even sweet spot, and a listening-window smoothness of 0.78 lifts it to a 6.48 preference score with an ideal subwoofer, so tonal balance holds as you shift around a desk. Watch for: Output tops out around 86dB, with heavy compression and very high distortion as it gets there, so it only suits nearfield listening at modest volume.
What the Monacor SOUND-4BT does well: 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. Watch for: Predicted in-room response remains uneven despite the modest midrange span.
Buy the Sovox MiniMax3. It is rated higher for sound quality, and saving $340 with the Monacor SOUND-4BT does not make up for the sound-quality gap.

The Two Speakers In Full
Sovox MiniMax3: $650 per pair Sovox eBay
Pros: A coaxial midrange and tweeter give a wide, even sweet spot, and a listening-window smoothness of 0.78 lifts it to a 6.48 preference score with an ideal subwoofer, so tonal balance holds as you shift around a desk. The 3.5-inch woofer and 5-inch passive radiator reach 66Hz at -3dB and about 53Hz at -12dB, deeper than most speakers this small. The unibody aluminum enclosure is solid and only 195mm tall, and Free, Desk, Wall and Desk & Wall presets plus treble and bass trims adapt it to its placement. Measured bass extension of 66Hz (-3dB).
Cons: Output tops out around 86dB, with heavy compression and very high distortion as it gets there, so it only suits nearfield listening at modest volume. Treble rises on axis (+0.35dB per octave), which holds its standalone preference score to 3.84; toeing it about 10 degrees away from your ears smooths the top end. Bass falls away quickly below 60Hz and there is no subwoofer output, and inputs are limited to balanced XLR and RCA.

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.
