Short answer: the KEF LS50 Wireless II for better sound quality, the Edifier S2000MKIII for the lower price. The KEF LS50 Wireless II ranks #18 of 100 powered bookshelf speakers, rated 4.3/5, at $2,999. The Edifier S2000MKIII ranks #69, rated 3.5/5, at $529.99, $2,469.01 cheaper.
The case for the Edifier S2000MKIII: The available digitized response suggests substantial bass reach, with a -3dB estimate around 41Hz. The catch: The 4.0dB midrange span and uneven predicted room response suggest meaningful coloration.
The KEF LS50 Wireless II is the more accurate choice. 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 4.24 for the Edifier S2000MKIII. It keeps a wired aux input, which the Edifier S2000MKIII lacks. It has an adjustable EQ, which the Edifier S2000MKIII lacks. Watch for: The 3.0dB response span is good but not reference-leading, and dispersion still varies with frequency.
Buy the Edifier S2000MKIII if the price is the priority over sound quality, or the KEF LS50 Wireless II if sound quality is the priority over the price.

Edifier S2000MKIII: $529.99 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.

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.
