Short answer: the KEF LS50 Wireless II for better sound quality, the Edifier S2000MKIII for the lower price. The KEF LS50 Wireless II ranks #16 of 60 powered bookshelf speakers at $2999.99. The Edifier S2000MKIII ranks #29 at $594.98, $2405.01 cheaper.
What the Edifier S2000MKIII offers: Spinorama’s digitized measurements show unusually deep extension for a powered bookshelf speaker: 40.5Hz at -3dB and 37Hz at -6dB. Its preference score is 3.58 without a subwoofer and 5.34 with one, placing it just above the KRK Classic 5 and Edifier MR4 on the same with-subwoofer measure. It also accepts digital input up to 24-bit/192kHz. Watch for: The Spinorama record is low-quality data digitized from a scanned graph rather than an independent Klippel measurement, so the score carries more uncertainty. Frequency deviation is 4.0dB, predicted in-room smoothness is only 0.107, and the response needs substantial EQ around 1kHz and 3.3kHz to approach neutrality.
What the KEF LS50 Wireless II offers: Uni-Q coincident driver array (130mm aluminum woofer with a 25mm MAT dome tweeter mounted at its acoustic center) gives excellent, consistent off-axis dispersion, measuring the tightest directivity spread of this batch (directivity_spdi_stddev 3.96) alongside a smooth listening-window response (smoothness_listening_window 0.375, aad_on_axis 0.343). Bass extends to a genuinely deep 51.3Hz at -3dB / 41.5Hz at -10dB for a compact standmount, backed by a bi-amped 280W (LF) + 100W (HF) design. One of the most complete input sets in its class: HDMI eARC, optical, coaxial, RCA, Ethernet, AirPlay 2, Chromecast, Roon Ready, and Spotify/Tidal Connect, so it can replace a full receiver-based setup for TV, turntable, and streaming use. Watch for: Primary/Secondary architecture means one speaker handles every input while the other depends on a wireless or wired Ethernet link back to it - placement is less flexible than a fully symmetric pair. No mic-based automatic room correction, only fixed placement EQ presets in the KEF Connect app. Bass alignment Q (lfq 0.676) sits toward the higher end of typical ported values. At $2,999.99/pair it’s roughly double the price of KEF’s own smaller LSX II.
