Short answer: the SHIVAUDYO Point Zero. It ranks #29 of 119 powered bookshelf speakers by sound quality (rated 4.5/5); the Devialet Phantom Ultimate 108dB ranks #41 (rated 4.4/5).
The Devialet Phantom Ultimate 108dB is the deeper-bass choice. A single cabinet wireless speaker with astonishingly deep bass, nearly flat sound, and full streaming support for a complete music system. Its bass reaches about 21Hz before falling 3dB, against 31Hz for the SHIVAUDYO Point Zero. 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: Active speakers with balanced sound, useful deep bass, reduced rear energy, and a wide choice of analog and digital inputs. Watch for: Cardioid control begins around 200Hz rather than extending through all deep bass.
Buy the SHIVAUDYO Point Zero. It is rated higher for sound quality than the Devialet Phantom Ultimate 108dB.
