WiiM has officially unveiled three new products at High End Munich 2025: the Amp Ultra streaming amplifier, the Sound smart speaker, and the Sub Pro subwoofer. Together, they form a tighter, more connected ecosystem—one that now looks increasingly capable of challenging brands like Sonos and Apple on their own turf.
Known until now for affordable streaming gear that plays well with just about everything, WiiM is clearly leveling up. With this trio of devices, the company isn’t just expanding its lineup—it’s taking aim at the heart of modern home audio: integration, flexibility, and ease of use.
The WiiM Amp Ultra is the company’s most powerful and fully featured streaming amplifier yet. If you’re familiar with the WiiM Amp or Amp Pro, think of this as their more capable sibling—stronger, smarter, and more refined.
It’s built into a compact aluminum enclosure and features a 3.5-inch touchscreen that lets you do everything from switching sources to checking what’s playing. It’s the same screen from the WiiM Ultra streamer, and yes, it’s responsive enough to replace your phone for casual controls.
Under the hood, the Amp Ultra pushes out 100 watts per channel into 8 ohms, or 200 watts into 4 ohms, thanks to dual Texas Instruments Class-D amp chips. That’s enough power to drive up to four passive speakers, whether you're setting up a stereo system or filling multiple rooms.
For audio processing, WiiM has gone with the ESS ES9039Q2M SABRE DAC—capable of 32-bit/384kHz high-resolution playback—along with six TI op-amps to reduce distortion and noise. The result is a low noise floor and strong signal clarity, even at lower volumes.
On the connectivity side, it covers the bases: HDMI ARC, subwoofer output, Ethernet, Wi-Fi 6E, and Bluetooth 5.3 with LE Audio. And if you’re trying to simplify your setup, this box could replace both your amp and your streamer in one go.
The Amp Ultra also brings in support for Dolby Digital decoding and works well in 2.1 or 4.1 setups, making it a decent option for folks who want their TV audio to flow through their hi-fi system without juggling remotes or multiple apps.
Speaking of apps, everything runs through the WiiM Home App, which is surprisingly robust. You can tweak EQ settings, group rooms, manage playback, and even perform room correction. Streaming support includes Spotify Connect, TIDAL Connect, Chromecast, DLNA, Alexa Cast, and more. Apple fans take note, though: AirPlay is not supported.
Voice control is built in too. You can use Alexa, Google Assistant, or the included WiiM Voice Remote 2 to manage playback hands-free.
Alongside the Amp Ultra, WiiM is also launching the Sound: its first dedicated smart speaker. It’s compact, with a slightly rounded design that—let’s be honest—bears more than a passing resemblance to Apple’s HomePod. But while it may look familiar, its features and functionality are rooted firmly in WiiM’s broader platform.
The WiiM Sound features a 4-inch woofer and dual balanced-mode radiator tweeters, delivering a total of 100 watts of output. It supports hi-res streaming up to 192kHz/32-bit and works as a standalone speaker or part of a stereo pair.
You can also place it in a Dolby 5.1 setup as a center or surround speaker—a move that clearly targets Sonos users who’ve gotten used to building flexible wireless surround systems.
The speaker includes a 1.8-inch touchscreen, offering direct access to volume, playback controls, playlists, and presets. If you’re not big on fiddling with your phone every time you want to skip a track, this comes in handy.
Connectivity includes Wi-Fi 6E, Bluetooth 5.3, and Ethernet. Like other WiiM products, it supports Chromecast, Spotify Connect, TIDAL Connect, DLNA, and Alexa Cast. Again, there’s no AirPlay—something Apple loyalists will want to keep in mind.
Room correction is also available through the app, alongside a 10-band graphic and parametric EQ and 24 preset EQ profiles. That’s a lot of customization for a speaker that fits on a shelf or counter.
The third product rounding out the launch is the Sub Pro, an 8-inch wireless subwoofer designed to complement the rest of WiiM’s lineup. It’s powered by a 250W Class-D amplifier and covers a frequency range of 30Hz to 200Hz, making it suitable for both music and movies.
Like the Sound and Amp Ultra, the Sub Pro includes automatic room correction, helping it adapt to different acoustic environments without requiring manual EQ adjustments.
It connects via Wi-Fi or Bluetooth and includes an RCA input for traditional wired setups. There's also smart power management built in—the subwoofer automatically enters standby mode when it’s not receiving a bass signal and powers up again when needed.
WiiM clearly designed the Sub Pro with flexibility in mind. Whether you’re adding it to a 2.1 stereo rig with the Amp Ultra or dropping it into a living room home theater setup with a pair of Sound speakers, it slots in neatly. And it’s all managed through the same WiiM Home App.
With these three new products, WiiM is turning what used to be a handful of clever streamers into a fully-fledged ecosystem. While brands like Sonos have long dominated the multi-room wireless market and Apple’s HomePod family delivers deep iOS integration, WiiM is trying something a bit different: build an open, customizable platform that’s affordable and easy to scale.
All three devices—the Amp Ultra, Sound, and Sub Pro—will be available in Q3 2025 through Amazon and select retailers. Pricing hasn’t been announced yet, but if WiiM’s previous products are any indication, it’s likely they’ll undercut the competition.
