Short answer: the Devialet Phantom II 98 dB for better sound quality, the Edifier S2000MKIII for the lower price. The Devialet Phantom II 98 dB ranks #10 of 64 powered bookshelf speakers at $2998. The Edifier S2000MKIII ranks #29 at $699.99, $2298.01 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 Devialet Phantom II 98 dB offers: Exceptional bass for its tiny sealed enclosure measures 30Hz at -3dB, 25.8Hz at -6dB, and 22.4Hz at -12dB, with a well-damped 0.302 low-frequency Q. The 2.58 sound-power directivity-index standard deviation indicates broad, consistent dispersion, and preference scores reach 6.07 without a subwoofer and 7.15 with one. Each speaker integrates amplification, Wi-Fi, AirPlay 2, Spotify Connect, Roon, Bluetooth, Ethernet, and optical/analog input. Watch for: The medium-quality manufacturer measurement has a 2.3dB reference band and 0.590dB on-axis average absolute deviation, good rather than class-leading linearity. Stereo requires two individually powered network speakers and costs nearly $3,000; maximum output is rated at 98dB at 1m per speaker, and the all-in-one architecture offers less serviceability and system flexibility than conventional monitors.
Buy the Edifier S2000MKIII if the price matters more than sound quality. Buy the Devialet Phantom II 98 dB if sound quality matters more than the price.
