Devialet Phantom

[m1ts0s]

"The ADH Intelligence regulates Phantom’s entire mechanical functioning with absolute precision. This technology - exclusive to Devialet - is a powerful microprocessor hybridizing digital and analog technologies, which purifies and magnifies the audio signal.

Phantom integrates a unique system which emits ultra deep sounds by high pressure beating of its lateral wings.

Phantom's spherical conception is the perfect acoustic architecture when it comes to producing sound and spreading its energy evenly in all directions. Attention to details: there are no sharp edges on Phantom’s surface, to avoid diffraction along box surface.

Thanks to the EVO Platform, your system keeps getting better everyday - no human intervention required. Once set up in your home, Phantom will upgrade itself constantly, enhance its internal connections, connect to other Phantoms, react to your presence and improve continually."

"My eyes were immediately drawn to the rounded shape, which is ideal for a smooth, unobtrusive wavelaunch. Then they found the 1" tweeter nestled into the 5" midrange driver, which puts both drive units into the same acoustic space, allowing for consistent output in all directions. And finally I saw the side-mounted woofers, which are about 6" across and are not only placed in ideal proximity to the front two drivers, but also work to cancel cabinet vibrations since they fire from opposing sides. The drivers' diaphragms are made from aluminum. I also took note that the woofers and midrange diaphragms are convex, not concave like traditional drivers, and that the entire outer shell was made of some sort of composite material, which I found out is a mix of ABS and fiberglass.

Also mounted on the aluminum centerpiece are the power-supply components, the class-D amplifier section, and the DSP electronics. It's the DSP component that acts as the brains of each loudspeaker, because it's where the crossover manipulation (250Hz for the woofers to the midrange, 2kHz for the midrange to the tweeter) and driver optimization are done with topflight precision. I was told that both Phantom models are flat to within +/-0.5dB across the audioband, and can reach right down to 20Hz with high output, which is simply not possible with a conventional loudspeaker of similar size.

The digital guts in each speaker allow it to receive incoming digital music signals via Wi-Fi, wired Ethernet, and powerline Ethernet simultaneously if all are configured. This is not only unique, but useful since the concurrent operation creates redundancy and, therefore, greatly reduces the chance for dropouts compared to just one digital connection. There's also an optical connector, allowing the speaker to receive a digital signal from a Blu-ray player or something similar. Not formally part of either Phantom, but designed to work in conjunction with them, is a forthcoming product called Dialog ($349), which is essentially a purpose-built computer designed specifically to stream music to Devialet's speakers over a network, without the need for a formal computer. Users can control Dialog and the speakers through an app that Devialet is finishing development on now."

"It is commonly accepted, based on the laws of physics, that great loudspeakers have to be huge. Well the laws of physics cannot be changed, but sometimes there is a lot to gain by pushing them to their very limits. A lot can be done if you don’t rely on existing technologies, but are willing and able to develop new ones that serve your specific purpose. It is all a matter of going as far as is physically possible, by looking at a given technical challenge with a new perspective.

We decided on a performance we wanted to achieve, to create the ultimate home audio experience from a compact design, conveying the full music dynamics and physical impact:

| 16Hz to 25kHz bandwidth, ± 2dB
| 20Hz to 20kHz bandwidth, ± 0.5dB
| 105dB maximum SPL

The basic idea behind compact deep bass reproduction was to maximize the efficiency of the electro-acoustic system at every level. The consequences of this logic are simple:

| use sealed box architecture, for high efficiency at the lowest frequencies
| design the most efficient compact driver, with very long diaphragm excursion capability
| use symetric low-frequency units so as to cancel mechanical vibrations

Working with our designers, we decided to settle on a very challenging acoustic volume of maximum 2x3=6 liters, so as to keep PHANTOM within a very compact form factor. This is more than 20x smaller acoustic volume than what high-end audio speakers currently use to approach a similar deep bass performance. This of course created many realisation challenges. To name only one, the maximum air pressure inside the enclosure is 20 times higher than in a conventional speaker box. This pressure is equivalent to 174dB SPL,which is the acoustic pressure level associated with a rocket at launch...

This is why we call our technology Heart Bass Implosion ® : in order to create lifelike bass from such a compact enclosure, PHANTOM speaker drivers need to be able to create and resist extremely high pressure and vacuum inside the speaker box. We tried to use in the early prototypes the most robust loudspeakers we could find in the market, and the speaker drivers seemed to ‘implode’: the diaphragm fragmented itself into fractal shapes, sucked in by the excessive force resisting the speaker’s intended displacement. In order to realize this, we hired key engineers with very different and complementary expertise, coming from various industries:

| experts from the automotive industry, specialized in injection pumps, materials deformation
modeling, automated assembly for high pressure devices
| experts in micromechanics, specialized in designing and manufacturing high-precision metal parts
manufacturing for the watch industry
| experts in high-efficiency professional loudspeakers, specialized in performance repeatability and
reliability for live stadium concerts

The result of this unique, blank sheet approach, is Devialet’s first HBI ® woofer: a high efficiency, very long stroke (26mm peak-to-peak) yet very compact driver. Four times more powerful than the best woofers on the market of an equivalent diaphragm size, yet 6 times more compact and 6 times lighter. Each woofer can move a mass of more than 30kg."
