Short answer: the KEF LSX II LT. It ranks #45 of 65 medium powered bookshelf speakers at $594.98, ahead of the Edifier S2000MKIII at #26 for $549.99. Spinorama preference scores back up the gap: the LSX II LT measures 3.93 standalone and 6.16 with an ideal subwoofer, against 3.58 and 5.34 for the S2000MKIII.
The LSX II LT’s coincident driver design is its main measured advantage. Its Uni-Q-style layout keeps the tweeter centered in the midrange, giving useful consistency across listening positions, and its own notes flag a 3.4dB midrange response span with treble-region dips that keep it below more neutral studio monitors. Because the drivers are small, bass compression kicks in around 88 to 92dB per meter per speaker with rising distortion at higher levels, so it suits close desktop listening rather than filling a large room. It also has no analog input at all on this LT version, so a turntable can’t plug straight in.
The S2000MKIII counters with more traditional connectivity and deeper measured bass extension. It supports high-resolution digital input up to 192kHz/24-bit alongside two RCA inputs, optical, and coaxial digital, giving it more ways to hook up sources than the Wi-Fi and HDMI-focused LSX II LT. Its own notes estimate a -3dB point around 41Hz, deeper than the LSX II LT’s roughly 56Hz, though they also flag a 4.0dB midrange span and uneven predicted room response that suggest meaningful coloration, with a caution that favorable modeled EQ results shouldn’t be mistaken for how the stock speaker actually sounds.
Buy the KEF LSX II LT for better overall measured preference scores and Wi-Fi/HDMI convenience, if you don’t need an analog input.
Buy the Edifier S2000MKIII if you need real RCA or coaxial digital inputs, or want deeper bass extension for less careful nearfield listening.

Edifier S2000MKIII: $594.98 per pair Amazon eBay
Pros: The available digitized response suggests substantial bass reach, with a -3dB estimate around 41Hz. Scores are 3.58 standalone and 5.34 with an ideal subwoofer. Digital inputs and a self-contained stereo-pair format are convenient for general music listening.
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 LSX II LT: $549.99 per pair Amazon eBay
Pros: The coincident driver provides useful consistency across listening positions, and the app offers placement and subwoofer adjustments. Erin’s measurements give preference scores of 3.93 standalone and 6.16 with an ideal subwoofer, with -3dB bass around 56Hz. HDMI and USB connectivity make it convenient for a small TV or desktop system. Measured bass extension of 55Hz (-3dB), with a measured sensitivity of 84dB.
Cons: The 3.4dB midrange response span and treble-region dips keep it below more neutral monitors. The existing review finds bass compression around 88-92dB/1m and rising distortion at higher levels, so the small drivers suit close listening rather than a large room. This LT version has no analog input; a turntable cannot plug straight into it.
