Short answer: the KEF LS50 Wireless II for better sound quality, the Edifier MR4 for the lower price. The KEF LS50 Wireless II ranks #19 of 105 powered bookshelf speakers, rated 4.3/5, at $2,999. The Edifier MR4 ranks #71, rated 3.5/5, at $169.99, $2,829.01 cheaper.
The case for the Edifier MR4: Erin’s data supports a useful budget desktop monitor: a 3.0dB midrange span, little overall on-axis tilt, and preference scores of 3.25 standalone and 6.00 with an ideal subwoofer. The tradeoff: Bass reaches -3dB around 79Hz, so deep extension should not be inferred from the overall flat trend.
The KEF LS50 Wireless II is the more accurate, deeper-bass option. Erin’s measurements give preference scores of 5.43 standalone and 7.51 with an ideal subwoofer, with a -3dB point around 51Hz. Its measured preference score, a predictor of how neutral it sounds, is 5.43 against 3.25 for the Edifier MR4. Its bass reaches about 51.3Hz before falling 3dB, against 79Hz for the Edifier MR4. Watch for: The 3.0dB response span is good but not reference-leading, and dispersion still varies with frequency.
Buy the Edifier MR4 when the price outweighs sound quality for you, and the KEF LS50 Wireless II when sound quality outweighs the price instead.

The Two Speakers In Full
Edifier MR4: $169.99 per pair Amazon eBay
Same family: the Edifier MR3 (smaller bookshelf, rated 3.8/5), the Edifier MR4.5 (larger bookshelf, ranked higher, rated 3.6/5) and the Edifier MR5 (larger bookshelf, ranked lower, rated 3.3/5).
Pros: Erin’s data supports a useful budget desktop monitor: a 3.0dB midrange span, little overall on-axis tilt, and preference scores of 3.25 standalone and 6.00 with an ideal subwoofer. Balanced TRS inputs and tone controls are practical at its price, and its response is more balanced than the measured Edifier R1280T. Measured bass extension of 79Hz (-3dB), with a measured sensitivity of 78dB.
Cons: Bass reaches -3dB around 79Hz, so deep extension should not be inferred from the overall flat trend. Listening-window response still has local irregularities, including lower-treble unevenness. The existing review reports rapidly increasing distortion and audible distress when pushed well above moderate desktop levels. No Bluetooth, and adding a subwoofer does not cure every output or tonal limitation.

KEF LS50 Wireless II: $2,999.00 per pair Amazon KEF Crutchfield eBay
Same family: the KEF LSX II LT (smaller bookshelf, ranked lower, rated 4/5), the KEF LSX II (smaller bookshelf, estimated 4.1/5) and the KEF LS60 (floorstanding, rated 4.8/5).
Pros: Erin’s measurements give preference scores of 5.43 standalone and 7.51 with an ideal subwoofer, with a -3dB point around 51Hz. The coincident Uni-Q layout helps preserve tonal consistency across horizontal and vertical listening positions. Low listening-window narrow-band deviation of 0.308 supports relatively clean midrange reproduction. HDMI eARC and streaming functions make it a capable all-in-one stereo system. Measured bass extension of 51.3Hz (-3dB).
Cons: The 3.0dB response span is good but not reference-leading, and dispersion still varies with frequency. Compact bass drivers limit deep-bass output. App placement adjustments are not the same as microphone-based automatic room correction. The price and primary/secondary architecture are practical trade-offs; neither driver geometry nor a single directivity statistic guarantees the best sound in every room.
