Short answer: the SHIVAUDYO Point Zero. It ranks #21 of 68 powered bookshelf speakers by sound quality (rated 4.5/5); the Devialet Phantom Ultimate 108dB ranks #29 (rated 4.4/5).
The case for the Devialet Phantom Ultimate 108dB: Erin’s measurements show full bass output all the way down to about 20Hz, the lowest frequency measured, which is remarkable from a single cabinet about 34cm deep. Watch for: DSP limiting and compression take over near maximum volume, so the deep bass you hear at moderate levels shrinks when you push it; Erin’s 96dB distortion test ran into the limiter.
What the SHIVAUDYO Point Zero does well: Measured -3dB extension of 31.5Hz and a 7.66 ideal-subwoofer score combine useful bass with broadly balanced sound. Watch for: Cardioid control begins around 200Hz rather than extending through all deep bass.

Devialet Phantom Ultimate 108dB: $7,998 per pair Amazon B&H Photo Video eBay
Pros: Erin’s measurements show full bass output all the way down to about 20Hz, the lowest frequency measured, which is remarkable from a single cabinet about 34cm deep. The listening window is close to flat, with a -0.04dB per octave tilt and 0.80 smoothness, earning a 6.73 preference score on its own and 7.38 with an ideal subwoofer. Directivity is smooth, so room reflections keep the same tonal balance as the direct sound. Wi-Fi 6 streaming with AirPlay 2, Google Cast, Spotify Connect, TIDAL Connect and Roon Ready, plus Ethernet and optical inputs, makes one unit a complete music system. Measured bass extension of <21Hz (-3dB).
Cons: DSP limiting and compression take over near maximum volume, so the deep bass you hear at moderate levels shrinks when you push it; Erin’s 96dB distortion test ran into the limiter. Stereo means buying two units, which puts a pair well above conventional powered monitors that measure as well. There is no analog input or subwoofer output, and the rounded shape does not sit on a shelf or desk stand like a box speaker.

SHIVAUDYO Point Zero: €6,500 per pair Shivaudyo eBay
Pros: Measured -3dB extension of 31.5Hz and a 7.66 ideal-subwoofer score combine useful bass with broadly balanced sound. Cardioid control through the low midrange reduces some rearward energy, and selectable bass presets let the listener trade extension for headroom. Measured bass extension of 31Hz (-3dB), with a measured sensitivity of 92.9dB.
Cons: Cardioid control begins around 200Hz rather than extending through all deep bass. Listening height can change vocal weight, and the measured 2.0dB midband span does not capture every directional variation. The deepest bass preset sacrifices output, so its nominal cutoff is not a clean-SPL guarantee.
