Short answer: the KEF LS50 Wireless II for better sound quality, the Edifier S1000W for the lower price. The KEF LS50 Wireless II ranks #16 of 64 powered bookshelf speakers at $2999. The Edifier S1000W ranks #46 at $599.99, $2399.01 cheaper.
What the Edifier S1000W offers: High resolution digital input up to 192khz/24bit. Wifi Watch for: No independent measurements exist - reviews are limited to informal YouTube sound-comparison videos. As one of Edifier’s warmer-tuned lifestyle HiFi speakers, it isn’t voiced for the flat, neutral response of a measurement-verified monitor.
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.
