Short answer: the Edifier MR3. It ranks #8 of 24 powered bookshelf speakers by sound quality, rated 3.8/5, at $109.99; the Monoprice Monolith MM-3 ranks #16, rated 3.2/5, and costs $299.99, which makes this an easy call rather than a real tradeoff.
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.
Why pick the Monoprice Monolith MM-3: With the ports plugged, Erin’s Klippel data yields preference scores of 3.82 standalone and 6.24 with an ideal subwoofer, and a measured -3dB point around 62Hz. The catch: These measurements describe modified, port-plugged speakers, not the stock product.
Buy the Edifier MR3. It is rated higher for sound quality than the Monoprice Monolith MM-3 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Speakers In Full
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.

Monoprice Monolith MM-3: $299.99 per pair Monoprice eBay
Pros: With the ports plugged, Erin’s Klippel data yields preference scores of 3.82 standalone and 6.24 with an ideal subwoofer, and a measured -3dB point around 62Hz. The reviewer found blocking the ports improved the bass peak and midrange resonances. Bluetooth, analog inputs, a headphone jack and angled stands provide a convenient compact desktop package.
Cons: These measurements describe modified, port-plugged speakers, not the stock product. Even in that configuration the review identifies substantial tonal problems and recommends off-axis placement to reduce excess treble. The score therefore does not justify ranking the stock MM-3 alongside better-balanced monitors. Small drivers limit its application, and the proprietary inter-speaker cable complicates replacement.
