#11 Devialet Phantom II 98 dB: $2,998/pair Devialet eBay
Pros: Exceptional bass for its tiny sealed enclosure: Spinorama estimates 30Hz at -3dB and 22.4Hz at -12dB. The measured response is smooth, dispersion is very broad, and each compact speaker integrates amplification, Wi-Fi, AirPlay 2, Spotify Connect, Roon, Bluetooth, Ethernet, and optical/analog input.
Cons: Stereo requires two individually powered network speakers and costs nearly $3,000. Maximum output is 98dB at 1m per speaker, and the unusual all-in-one architecture offers less serviceability and system flexibility than conventional monitors.
How it compares: Just above it: Sigberg Audio SBS Gen 2 - $15045 more, 50W less output power. Just below it: JBL 305P MKII - $2679 cheaper, 319W less output power.
