Short answer: the Edifier S2000MKIII. It ranks #69 of 100 powered bookshelf speakers by sound quality (rated 3.5/5); the M-Audio BX4 D3 ranks #73 (rated 3.4/5).
The Edifier S2000MKIII is the more accurate pick. The available digitized response suggests substantial bass reach, with a -3dB estimate around 41Hz. Its measured preference score, a predictor of how neutral it sounds, is 4.24 against 3.29 for the M-Audio BX4 D3. The tradeoff: The 4.0dB midrange span and uneven predicted room response suggest meaningful coloration.
Why pick the M-Audio BX4 D3: Balanced TRS, RCA and front auxiliary/headphone connections, plus tone controls, make this a flexible inexpensive desktop pair. It keeps a wired aux input, which the Edifier S2000MKIII lacks. Watch for: A rising response of about 0.62dB per octave and listening-window deviation of 0.546 indicate bright, locally uneven reproduction.
Buy the Edifier S2000MKIII. It is rated higher for sound quality than the M-Audio BX4 D3.

Edifier S2000MKIII: $594.99 per pair Amazon eBay
Older model: the Edifier S2000 Pro (ranked higher, rated 3.7/5).
Pros: The available digitized response suggests substantial bass reach, with a -3dB estimate around 41Hz. Scores are 4.24 standalone and 5.99 with an ideal subwoofer. Digital inputs and a self-contained stereo-pair format are convenient for general music listening. Digital input handles high-resolution audio up to 192kHz/24-bit.
Cons: The 4.0dB midrange span and uneven predicted room response suggest meaningful coloration. Favorable modeled EQ results should not be treated as the sound of the stock speaker or as proof that all dispersion issues are correctable.

M-Audio BX4 D3 eBay
Same family: the M-Audio BX5 D3 (larger bookshelf, ranked higher, rated 3.9/5) and the M-Audio BX8 D3 (larger bookshelf, rated 4/5).
Pros: Balanced TRS, RCA and front auxiliary/headphone connections, plus tone controls, make this a flexible inexpensive desktop pair. The third-party measurement gives scores of 3.29 standalone and 6.03 with an ideal subwoofer, with -3dB bass estimated around 67Hz.
Cons: A rising response of about 0.62dB per octave and listening-window deviation of 0.546 indicate bright, locally uneven reproduction. The compact system suits moderate nearfield use; the preference estimate does not verify high-level headroom.
