Product Insights
The Phantom II 98 dB is a factory-calibrated wireless speaker that achieves 0.001% distortion and a 7.0 Harman score with SAM driver protection, delivering stable stereo imaging and 18 Hz bass from an 11.6 L stereo pair that replaces separate components. However, its all-in-one design comes with tradeoffs: Bluetooth supports only AAC/SBC, users report connectivity drops that require wired Ethernet, and wireless surround is not supported, despite firmware updates restoring streaming features and providing Roon Ready high-res playback.
- Calibration
Factory-calibrated via laser measurement of 60+ driver parameters per unit.
Why this is supported
Each Phantom II driver is individually characterized using SAM's semi-automated laser vibrometry, capturing more than 60 parameters per driver model.
SAM® analyzes transducer characteristics using laser technology. These include displacement, deformation, maximum displacement, speed and acceleration.
monoandstereo.comThis ensures the on-board digital correction is precisely matched to the aluminum Full-Range and Bass drivers—eliminating tonal mismatch or pre-echo common in generic DSP. Moreover, SAM is factory-calibrated and requires no user setup, so every unit delivers this precise matching out of the box.
No changes to set-up are required.
monoandstereo.com- Protection
SAM continuously monitors each driver's Safe Operating Area to prevent overload.
Why this is supported
Using the laser-measured driver data, SAM computes the exact Safe Operating Area of each transducer in real time. This dynamic limiter prevents over-excursion and thermal overload, which is why the 4.3 kg sealed Phantom II can sustain its 98 dB SPL peak without audible distress or damage.
The collected data also allows us to calculate the transducer SOA (Safe Operating Area). By doing so, SAM® offers permanent protection from overload, letting users reach higher volumes than ever before.
monoandstereo.com- Sound quality
Co-designed open-loop SAM yields 7.0 Harman score, no pre-echo.
Why this is supported
SAM operates strictly via open-loop processing—no microphone or feedback loop—so it introduces zero pre-echo or timing smear, preserving transient snap and imaging. The technology was co-developed with the Phantom line rather than retrofitted, ensuring deep integration with the sealed-chamber coaxial architecture. That integration contributes to objectively measured performance: the Phantom II achieves a Harman preference score of 7.0 (8.1 with a subwoofer) in independent spinorama testing, outperforming the Phantom I (5.7) and rivaling high-end passive monitors.
A temporal process, SAM® runs on an open loop and without sensors. No changes to set-up are required. The process is strictly causal and generates no pre-echo.
monoandstereo.comDumont alluded that the technology which became SAM did originate from the work done with Phantom.

pierreaubert.github.io- Distortion
Distortion remains below 0.001% even at 98 dB output.
Why this is supported
The Phantom II's ADH amplifier achieves a distortion of 0.001% THD, confirmed by independent sources.
Distortion is quoted at a vanishingly low 0.001% THD.
stereonet.comThis low distortion is enabled by the Magic Wire DAC design, which bypasses operational amplifiers and current mirrors, as detailed:
the output current of the highest performance DAC on the market (Texas Instrument PCM1792) is directly converted into high-voltage without any processing in between: no operational amplifier, no current mirror
hificlube.netBecause the distortion remains low even at 98 dB peaks, a stereo pair preserves spatial cues such as reverb decay and panning without hardening, maintaining a crisp soundstage.
- Stereo imaging
SAM-calibrated drivers and 0.001% THD deliver stable, precise stereo imaging.
Why this is supported
The single full-range driver avoids crossover phase rotation. As
While the Phantom I uses a tweeter, this was dropped from the Phantom II to meet the exacting requirements dictated by the compact package.
stereonet.comThe spherical enclosure ensures even dispersion:
Designed for optimal sound performance, the active spherical design of the Devialet Phantom II ensures that you experience beautifully rich and unspoiled acoustics no matter where you are.

What are the most effective troubleshooting steps for the frequent connectivity drops reported by users?For optimal soundstage and bass, placement at ear level and away from walls is recommended:
For optimal soundstage, place the speaker at ear level and away from walls; for deeper bass, position it near a wall or corner. Avoid placing it inside a cabinet.
Is there a recommended stand or placement for the Phantom II to achieve the best soundstage and bass response?The compact size of a stereo pair also saves space, as noted:
At 157×168×219 mm each, a stereo Phantom II pair occupies roughly 11.6 liters total volume while housing amplification, DAC, and streaming — a footprint that merely matches the volume of a typical integrated amplifier chassis, making it possible to get deep, detailed stereo sound in rooms where a full-size hi-fi rack is visually or spatially impossible.
How the Phantom II compares to traditional hi-fi setups — system_footprint_vs_separates- Build construction
Aluminum composite cabinet with zero internal wiring and automotive-grade construction.
Why this is supported
Devialet builds the Phantom II using a bi-injected composite cabinet, described as
bi-injected composite comprising an inner polycarbonate layer reinforced by fiberglass and a metal insert for extra rigidity, a polished ABS outer shell, and a pressure-injected aluminum central core
Build quality and materials for long-term durability — bi_injected_composite_body_with_metal_insert. This construction allows for elimination of internal wiring, as one reviewer notes:
resulting in a level of precision that allows the company to build the Phantom with reportedly a complete absence of internal wiring.

Some say that they need to be driven loud to balance out the bass. I don't find that and can listen to them at length at more modest listening levels. For me they fail on not being upscaled for surround. To go the route of surround I would have to replace with custom Phantoms that use Ethernet for connection. So as surround they are not a wireless solution. I went to WiSA speakers instead.

Recommendation for 2x Phantom II 98 dB over single 108 dB
If you ask in r/Audiophile you’d get some different answers. Personally I’ve never regretted my stereo 105dB setup. For me stereo is a must, so my advice would be rather 2x 98 than just one 108.

Positive experience with Phantom 98 dB and TV connection tip
Great review. I have the phantom 98db’s and I love them for music and movies. I do have a solution for you: I also used the optical cable, wired with my tv. The sound was very low if I compared it to Spotify Connect. I changed the connecting from my tv to a HDMI audio extractor, connected with my Apple TV. This solved the problem for me. If I watch a movie, it’s like you are in a movie theater. I love these things!

Mixed experience: great sound but horrible software and connectivity
I own a pair of Phantom II 95dB, they provide amazing sound quality but the software package is horrible, even i connected both of them via ethernet cable, still encountering connection issue occasionally, one speaker have no sound coming out, you have to restart or even reset to get things solved. But just be frank, i still cannot find any speaker in such compact size which can provide powerful bass like Phantom, they really save me a lot of space from additional subwoofer
