Short answer: the Edifier MR3. It ranks #8 of 24 powered bookshelf speakers by sound quality, rated 3.8/5, at $109.99. The M-Audio BX3 ranks #21, rated 2.9/5, at $89, $20.99 cheaper, which does not close the gap in sound quality.
Why pick the M-Audio BX3: Balanced TRS, RCA and auxiliary inputs, headphone output and high/low tone controls offer useful flexibility for an inexpensive desktop pair. Watch for: ASR’s data gives only 2.04 standalone and 5.18 with an ideal subwoofer.
Why pick the Edifier MR3: Erin’s measurements show little overall tilt across the listening window, helping voices retain a broadly natural balance at a desk. The catch: Local response ripples remain: the measured 300Hz-5kHz span is 4.5dB and listening-window narrow-band deviation is 0.538.
Buy the Edifier MR3. It is rated higher for sound quality, and the $20.99 saving on the M-Audio BX3 is not enough to make up the difference.

M-Audio BX3: $89.00 per pair Amazon eBay
Pros: Balanced TRS, RCA and auxiliary inputs, headphone output and high/low tone controls offer useful flexibility for an inexpensive desktop pair. The controls give some scope to adjust broad tonal balance for placement.
Cons: ASR’s data gives only 2.04 standalone and 5.18 with an ideal subwoofer. Listening-window narrow-band deviation of 0.580 indicates persistent tonal irregularities, while bass reaches -3dB at about 88Hz. The limited bass and uneven response make it a weak choice for accurate monitoring even with a subwoofer. Broad tone controls cannot precisely fix crossover or dispersion problems.

Edifier MR3: $109.99 per pair Amazon eBay
Pros: Erin’s measurements show little overall tilt across the listening window, helping voices retain a broadly natural balance at a desk. Scores of 3.91 standalone and 6.53 with an ideal subwoofer support it as a useful budget nearfield option rather than a reference monitor. Tone controls and app-based EQ provide unusually flexible adjustment, and its bass extends farther than the Fostex PM03’s. Measured bass extension of 70Hz (-3dB), with a measured sensitivity of 83.3dB.
Cons: Local response ripples remain: the measured 300Hz-5kHz span is 4.5dB and listening-window narrow-band deviation is 0.538. Bass reaches -3dB at about 70Hz. The limiter protects the drivers but prevents much extra loudness when pushed; existing compression testing puts effective single-speaker output around 86-87dB at 1m. Vertical crossover interference makes tweeter height and tilt important.
