Devialet Phantom Ultimate 108: the big sister of the Ultimate 98 pushes the boundaries of sound

Introduced in 2015, the first Devialet Phantom speaker made a lasting impression. For its performance relative to its size, particularly in the lower end of the spectrum for some, for its design and price for others. Ten years later, the French firm Devialet is offering a new Phantom series with two models, the Devialet Phantom Ultimate 98 and Devialet Phantom Ultimate 108. After our presentation of the first, we return as promised to the second, the Devialet Phantom Ultimate 108.

These ambitious names hide a new variation of the iconic Devialet Phantom speakers. On the program, a new connected platform, the removal of the core cover of the woofers which required a new assembly of the various elements of the speaker and a new grille for the wideband speaker placed under the sign of purity for an improved sound opening. Namely, six months of studies and developments were required to harmoniously combine aesthetic evolution and sound performances.

Technically, the Devialet Phantom Ultimate 108 integrates four speakers (compared to three on the Ultimate 98), a tweeter with a new generation aluminum dome, a midrange also with a new generation aluminum dome "surrounded" by two [abc]boomers[/abc] with ABS dome, again of the new generation. This configuration allows engineers to get closer to the concept of the pulsating sphere, the only form capable of avoiding diffraction problems at the surface of the speaker, as Olson's work highlighted in the 1940s. This particular development is known at Devialet under the name ACE (for Active Cospherical Engine).

For its part, amplification is provided by as many new generation ADH amplifiers (one per speaker) directly derived from those present in Devialet amplifiers. The formidable rendering of low frequencies is the work of the HBI or Heart Bass Implosion process. In short, it allows, with its acoustic volume, a reproduction of bass equivalent to that of a speaker twenty times larger. To achieve this incredible result, you should know that the acoustic pressure within the Devialet Phantom is twenty times higher than that of a conventional speaker, equivalent to 174 dB SPL, that of a rocket at takeoff. Finally, the HBI process offers bass of unprecedented depth which will inevitably appeal to music lovers and connoisseurs given the volume of the Devialet Phantom.

Another essential element of the Devialet Phantom Ultimate 108 is the integration of the Sam (Speaker Active Matching) system which allows the signal supplied by the amplifier to the speakers to be finely optimized according to their qualities and capacities, all in real time. Thus, the sound reproduction always gets the best out of the speakers, in all circumstances, whatever the type of music.

Devialet Phantom Ultimate 108, implementation££££

As you have probably already understood, the Devialet Phantom Ultimate 108 can be used alone, as a network speaker via the [abc]Wi-Fi[/abc] functionality, the [abc]Ethernet[/abc] port or a simple speaker through the [abc]optical[/abc] input, but also in duo to create a stereo audio system. Or within a multiroom configuration through the [abc]AirPlay 2[/abc], [abc]Chromecast (integrated)[/abc] or Roon protocols.

Namely, the Devialet application gives access to all [abc]streaming[/abc] music services and can access, thanks to the [abc]UPnP[/abc] ([abc]DLNA[/abc]) audio gateway function, content stored on a [abc]Nas[/abc] hard drive or a computer via [abc]Ethernet[/abc], [abc]Wi-Fi[/abc] 5 Dual Band, [abc]Bluetooth[/abc] 5.3 or AirPlay 2 and Google Cast already mentioned. Note that the Devialet Phantom Ultimate 108 is Spotify Connect certified (up to the [abc]Lossless[/abc] version) and Tidal Connect.

It is also worth mentioning the latest version of the DOS3 operating system, launched with the Devialet Astra amplifier, a total power of 1,100 W, file management up to 192 kHz/24 bits, a new SoC (System on Chip) based on the new Quad Core NXP i.MX 8M Nano chip, a frequency response of 14 Hz-35 kHz, IP43 certification and the presence of four touch buttons.

The word to Jacques Demont, Devialet CEO££££ "Devialet is more ambitious than ever. With Devialet Phantom Ultimate, we are once again confirming our status as a pioneer in the audio industry. This new generation offers the possibility of experiencing sound with unprecedented intensity and an unprecedented level of clarity and depth. Behind this feat lies the excellence of our engineering, a testament to our know-how and expertise.
