Short answer: the Edifier S2000MKIII for better sound quality, the M-Audio BX4 D3 for the lower price. The Edifier S2000MKIII ranks #29 of 64 powered bookshelf speakers at $699.99. The M-Audio BX4 D3 ranks #56 at $149, $550.99 cheaper.
What the Edifier S2000MKIII offers: Spinorama’s digitized measurements show unusually deep extension for a powered bookshelf speaker: 40.5Hz at -3dB and 37Hz at -6dB. Its preference score is 3.58 without a subwoofer and 5.34 with one, placing it just above the KRK Classic 5 and Edifier MR4 on the same with-subwoofer measure. It also accepts digital input up to 24-bit/192kHz. Watch for: The Spinorama record is low-quality data digitized from a scanned graph rather than an independent Klippel measurement, so the score carries more uncertainty. Frequency deviation is 4.0dB, predicted in-room smoothness is only 0.107, and the response needs substantial EQ around 1kHz and 3.3kHz to approach neutrality.
What the M-Audio BX4 D3 offers: Affordable compact powered pair with 4.5-inch Kevlar woofers, rear EQ controls, balanced TRS, RCA and front-panel aux/headphone connections. Spinorama predicts a 5.14 preference score with a subwoofer and useful nearfield bass extension near 62Hz. Watch for: The third-party measurement is low confidence, and the small shared-amplifier design has limited output and bass headroom. Its raw no-subwoofer preference score is modest, the rear port complicates wall placement, and only the left cabinet contains amplification and controls.
Buy the Edifier S2000MKIII if sound quality matters more than the price. Buy the M-Audio BX4 D3 if the price matters more than sound quality.
If sound quality matters at all to you, skip the M-Audio BX4 D3. It ranks near the bottom of the 64 powered bookshelf speakers, so look higher up the list instead.
