Devialet’s “new Bluetooth speaker” from 2018, the Phantom Reactor, is no longer new and no longer sold as a current model. The Reactor was renamed Phantom II, Devialet now lists the Phantom II in the legacy section of its store, and the speakers that actually carry Bluetooth in 2026 are the battery-powered Mania and the mains-powered Phantom Ultimate 98 dB and 108 dB.
The price ladder is steep. Mania launched at $790, the compact Phantom Ultimate 98 dB costs $1,900 per speaker, and the flagship 108 dB is $3,800. What follows is what each model offers, where the old Reactor fits, and who should pay this much for a wireless speaker.
This assessment draws on Devialet’s specifications and published reviews. TechEngage has not independently tested these speakers.
Devialet Bluetooth speakers compared: prices, power and connectivity
| Model | US price | Power | Key connectivity | Status |
|---|---|---|---|---|
| Phantom Reactor 600 / 900 (2018) | $999 / $1,299 at launch | Mains | Bluetooth 4.1, Wi-Fi, AirPlay, Spotify Connect, optical | Renamed Phantom II, now legacy |
| Phantom I 103 dB / 108 dB (2021) | From £1,890 (UK) at launch | Mains | Wi-Fi, Bluetooth, AirPlay 2, Roon | Legacy |
| Mania (2022) | $790 at launch, $900 list by 2023 | Battery, up to 10 hours | Bluetooth 5.0, Wi-Fi, AirPlay 2, Spotify Connect | Current |
| Phantom Ultimate 98 dB (2025) | $1,900 | Mains | Bluetooth, Wi-Fi, AirPlay, Google Cast, Spotify Connect, Tidal Connect | Current |
| Phantom Ultimate 108 dB (2025) | $3,800 | Mains | Same streaming options as the 98 dB | Current |
Two things stand out. Only Mania has a battery, so it is the only true portable, and every Phantom needs a wall socket despite the “Bluetooth speaker” label retailers often attach to it. Prices are also drifting upward: authorized US dealer Audio Advice lists the Phantom Ultimate at $1,999 and $3,999, about $100 and $200 above the launch prices. The same dealer notes there is no HDMI ARC, so TV sound runs over optical.
Phantom Reactor: what Devialet launched in 2018
Devialet announced the Phantom Reactor in October 2018 as a shrunken version of its original Phantom, measuring 219 x 157 x 168 mm. Preorders opened at $999 / £990, and at the same time the full-size Phantom was renamed Phantom Premier. Two versions shipped: the Reactor 600, with 600W of amplification and a 95 dB maximum output, and the Reactor 900, with 900W and 98 dB. TechRadar’s review lists the Reactor 900 at $1,299 / £1,290 and points out it is not portable at all: it needs mains power and weighs 4.3 kg.
Connectivity was broad for the time. Launch coverage from audioXpress lists Bluetooth, Spotify Connect, AirPlay, UPnP and a combined analog and optical input, with multiroom support for up to 25 Phantoms on one network. SoundStage! Simplifi’s 2019 review adds the details: dual-band Wi-Fi, Bluetooth 4.1, Gigabit Ethernet, and HomePlug networking over household wiring for stereo pairs. By then US prices had risen to $1,090 and $1,350.
The Reactor has no microphone and no built-in voice assistant. Devialet executives said at launch they had no plans for voice control, and What Hi-Fi’s Reactor 600 review lists Alexa and Google Assistant support as absent. That review praised the design and the bass but found the timing and musicality less convincing than the price suggested.
What happened to the Phantom Reactor
In February 2021, alongside the new Phantom I, Devialet renamed the Phantom Reactor as Phantom II. The 95 dB model corresponds to the Reactor 600 and the 98 dB model to the Reactor 900. Phantom I replaced the Premier line in 103 dB and 108 dB versions, added AirPlay 2 and Roon support, and started at £1,890.
Both are now past-generation products. Devialet’s own store files the Phantom II 98 dB under its legacy section, and old Phantom II product addresses point shoppers to Phantom Ultimate instead. A used Reactor or Phantom II can still make sense if you mainly stream over AirPlay or Spotify Connect and find one at a large discount. Check the seller’s return policy, because a speaker with a proprietary amplifier is not something a local repair shop can easily fix.
Devialet Mania: the portable Bluetooth speaker
Mania is the Devialet most people mean when they search for a Devialet Bluetooth speaker. It launched in November 2022 at $790 as the company’s first portable speaker, with up to 10 hours of battery life at moderate volume, IPX4 splash resistance, Bluetooth 5.0, Wi-Fi, AirPlay 2, Spotify Connect and Alexa through four built-in microphones. Those microphones also drive its automatic calibration, which adjusts the sound depending on how close the speaker sits to a wall.
Tom’s Guide’s review lists a $900 list price, a 5-pound weight, and a charging dock sold separately for $100. Pocket-lint lists a 2.3 kg weight with four 25W full-range drivers and two 38W woofers, rated it 4 out of 5, and flagged two practical limits: no aptX support, and battery life that drops quickly when you push the volume.
Devialet has kept refreshing the finishes rather than the hardware, and its store now carries newer colors such as Mania White Mist. If Mania is going to anchor a room with Alexa or AirPlay 2 groups, TechEngage’s guide to building a smart home around one ecosystem covers the platform choice that matters more than the speaker.
Verdict on Mania: it suits someone who wants one speaker to move between rooms, the patio and the occasional weekend away, and who values sound and design over maximum runtime. At 5 pounds with a 10-hour ceiling, it is a carry-around home speaker more than a beach or hiking speaker.
Phantom Ultimate 98 dB and 108 dB: the current Phantoms
Phantom Ultimate arrived in 2025 as the replacement for the Phantom I and II generation. SoundStage! Simplifi’s review of the 98 dB gives the numbers: 400W of amplification, 98 dB maximum output, an 18Hz to 25kHz frequency range, 9.5 pounds, and a price of $1,900 / £1,400 per speaker, or $2,400 for the gold-leaf Opéra de Paris edition. The 108 dB is a three-way design with 1,100W and a 108 dB ceiling at $3,800, or $4,300 in the Opéra finish.
Streaming is the biggest upgrade over the Reactor. The 98 dB supports Wi-Fi 5, Bluetooth 5.2 with SBC and AAC, AirPlay, Google Cast, Spotify Connect with lossless support, Tidal Connect, UPnP and Roon Ready, plus Ethernet and an optical input on the back. Google Cast means Android users get a proper Wi-Fi option instead of falling back to Bluetooth, which also makes the Phantom easier to fold into a setup built on Chromecast casting. For the flagship, Devialet’s Phantom Ultimate 108 dB page shows the flagship in its Light Pearl and Deep Forest finishes.
The newest Phantom is not a Bluetooth speaker at all. In July 2026, Devialet announced the Phantom Ultimate CI for custom installers, in 98 dB and 108 dB versions, with Wi-Fi and Bluetooth replaced by wired Dante audio networking. It is aimed at home theaters and commercial installs. And if TV sound is your main goal, the Dione soundbar is Devialet’s dedicated option; What Hi-Fi’s Dione review tested it at $2,399.
Is a Devialet speaker worth the price?
For most buyers, no. For a specific kind of buyer, yes. The case for Devialet is a lot of clean, deep bass from a very small box, a design that looks like nothing else, and wide support for streaming standards. The case against is value. A stereo pair of Phantom Ultimate 98 dB speakers costs $3,800, and SoundStage! Simplifi pointed out that the same money buys excellent conventional speakers plus an amplifier. What Hi-Fi made a similar point about pairing two Reactor 600s back in 2019.
A Devialet makes sense if you want one or two compact speakers to replace a hi-fi system in a small or medium room, you stream over AirPlay, Google Cast, Spotify Connect or Tidal Connect, and the object itself matters to you. It makes less sense if you want HDMI ARC for a TV, all-day battery life, or the most sound per dollar.
Cheaper alternatives
The closest rival to Mania is the Sonos Move 2. What Hi-Fi tested it at $449 in 2023, with Wi-Fi 6, Bluetooth 5.0 and AirPlay 2, and Tom’s Guide lists up to 24 hours of battery life, more than double Mania’s rated runtime, although Tom’s Guide found it too heavy to carry far. For home streaming speakers from Sonos, Bose, JBL, Marshall and Klipsch, see TechEngage’s roundup of the best Wi-Fi speakers. If the speaker will mostly sit beside a computer, the best PC speakers for laptops and desktops cost a fraction of any Devialet. And if you are still choosing between streaming services, these Spotify alternatives include Tidal, which works directly with Phantom Ultimate through Tidal Connect.
Which Devialet speaker should you buy?
- Mania: the choice for a portable, AirPlay 2 and Spotify Connect speaker that also works outdoors. Budget for the dock if you want easy charging.
- Phantom Ultimate 98 dB: for a bedroom, office or small living room, or as a stereo pair in a medium room. It is the practical successor to the Phantom Reactor.
- Phantom Ultimate 108 dB: for large rooms and people who listen loud. At $3,800 per speaker, audition it before buying if you can.
- Used Phantom Reactor or Phantom II: only at a large discount, from a seller that accepts returns, and with the older Bluetooth 4.1 hardware in mind.
- Skip Devialet if value, long battery life or HDMI TV connectivity matters more than design and compact bass.
Devialet speaker FAQs
Is the Devialet Phantom Reactor discontinued?
Yes, in practice. The Phantom Reactor was renamed Phantom II in 2021, and Devialet now lists the Phantom II in the legacy section of its store. The current compact Phantom is the Phantom Ultimate 98 dB, priced at 1,900 US dollars at launch.
What is the difference between the Phantom Reactor and the Phantom II?
They are the same speaker family under a new name. The Reactor 600 (600W, 95 dB) became the Phantom II 95 dB and the Reactor 900 (900W, 98 dB) became the Phantom II 98 dB when Devialet renamed the range in February 2021.
Does the Devialet Mania have Bluetooth and AirPlay?
Yes. Mania supports Bluetooth 5.0, Wi-Fi, AirPlay 2 and Spotify Connect, and it has Alexa built in through four microphones. It does not support aptX, so Android phones connect over standard Bluetooth codecs.
How long does the Devialet Mania battery last?
Devialet rates Mania at up to 10 hours at moderate volume. Reviewers found runtime drops noticeably at high volume, so plan on less than 10 hours if you use it for loud outdoor listening.
Does the Devialet Phantom Ultimate have a battery?
No. Both Phantom Ultimate models run on mains power. They are wireless in the sense of streaming over Wi-Fi and Bluetooth, with AirPlay, Google Cast, Spotify Connect and Tidal Connect, but they are not portable speakers.
Is a Devialet speaker worth it?
It depends on what you value. A single Phantom Ultimate 98 dB costs 1,900 US dollars, and a stereo pair costs as much as a good conventional speaker and amplifier system. Buy one for compact size, deep bass and design; skip it if value per dollar or long battery life matters most.
