Sonos Arc vs Samsung Q990D, Detailed Feature Comparison
Channel Architecture and Speaker Configuration
Sonos Arc Ultra: The Arc Ultra technically supports a 9.1.4 channel setup, but only when paired with Sonos Sub (Gen 3 or Sub 4) and two Era 300 surrounds. Alone, the soundbar performs in a 5.0.2 configuration out of the box. It includes 14 drivers that power its upward-firing, side-firing, and front-facing arrays. The true modularity of the Sonos system allows users to scale their setup gradually, beneficial for those who value customization. However, it lacks actual rear speakers unless separately purchased, which can limit the native surround immersion for movies and games.
Samsung HW-Q990D: The Q990D ships with its full 11.1.4 channel setup pre-configured, including the soundbar, a wireless subwoofer, and two ready-to-go rear speakers with side- and up-firing drivers. With 22 total drivers across the system, the Q990D creates a broader three-dimensional surround with physical speakers doing much of the heavy lifting. For users seeking plug-and-play spatial immersion for home theater experiences, particularly in larger rooms, the Samsung setup is a more comprehensive package right out of the box.
Sound Format Support (Dolby Atmos & DTS:X)
Sonos Arc Ultra: Dolby Atmos is fully supported on the Arc Ultra, where the soundbar delivers vertically-layered effects using its up-firing speakers and psychoacoustic processing. This is well-tuned for content like Apple TV+ and Netflix originals. However, the Sonos Arc Ultra does not support DTS:X, a notable omission for Blu-ray or UHD collectors who rely on that codec. Its Atmos soundstage shines the most in controlled environments focused on dialogue and midrange clarity, but it remains limited when it comes to more cinematic or high-action DTS:X content.
Samsung HW-Q990D: The Q990D gives users both Dolby Atmos and DTS:X support, ensuring versatile playback compatibility across streaming platforms, discs, and gaming consoles. Audiophiles and movie lovers with expansive media libraries benefit from this flexibility, especially when using physical formats. Thanks to real rear speakers, sound effects steer more naturally across the room, making movies and games more engaging. Users on Reddit frequently cite this dual-format support as a reason to choose the Samsung model over Sonos, especially for immersive action content.
Connectivity Options and Passthrough
Sonos Arc Ultra: Sonos keeps its connectivity streamlined with a single HDMI eARC port and Wi-Fi support. While this works well within the Sonos ecosystem or with AirPlay 2-supported devices, the soundbar does not offer HDMI passthrough or support for formats like 4K@120Hz. This makes the Arc Ultra less suitable for setups where multiple external devices need routing through the soundbar. Also missing is any Bluetooth support, a commonly requested feature for casual listening that would make the device more flexible outside the Sonos app environment.
Samsung HW-Q990D: With two HDMI 2.1 passthrough ports alongside eARC, the Q990D provides true hub functionality. Gamers benefit the most, as it supports 4K@120Hz and VRR, ideal for PlayStation 5 and Xbox Series X setups. The bar also supports Bluetooth, allowing quick pairing with smartphones or laptops. This robust connectivity suite enhances the Samsung’s appeal in mixed-use media setups, particularly where users don’t want to rely on the TV as the central HDMI switch.
Expandability and Ecosystem Integration
Sonos Arc Ultra: One of Sonos’ biggest strengths is its modularity and seamless integration within a broader Sonos multi-room setup. The Arc Ultra can be paired with other Sonos speakers like the Era 100 or Era 300s, plus Sub Gen 3 or Sub Mini. For users heavily invested in the Sonos app or already owning Sonos speakers, this system creates unmatched synergy. However, the cost of full expansion to match Samsung’s included setup can be significantly higher, and full room calibration via Trueplay only works on iOS devices.
Samsung HW-Q990D: While Samsung also offers multi-room audio compatibility through its SmartThings platform, it is not as comprehensive or modular as Sonos. The Q990D doesn’t support incremental speaker upgrades; what you get in the box is what you use. However, for many users, especially those with Samsung TVs, the system integrates via Q-Symphony, syncing TV speakers with the soundbar to enhance front imaging. This synergy adds value for Samsung ecosystem participants but may carry less weight for users outside that brand realm.
Room Calibration and Audio Optimization
Sonos Arc Ultra: The Arc Ultra features Trueplay room tuning, which analyses your space using iOS-enabled devices. When optimized, it delivers finely tuned sound signatures tailored to your room’s dimensions and reflective surfaces. This makes it ideal for medium-sized spaces where acoustic optimization enhances musical playback. However, the iOS-only limitation of Trueplay remains a frustration for Android users, who must rely on less precise factory tuning unless they borrow an Apple device during setup.
Samsung HW-Q990D: Samsung uses its SpaceFit Sound Pro calibration tool, which works automatically and supports both iOS and Android environments. It’s designed for real-time room analysis and acoustic adjustment, with minimal user involvement. This hands-off approach ensures a consistent setup experience regardless of device ownership and makes the Q990D especially user-friendly. While it may not deliver the same level of musical micro-tuning as Trueplay, it prioritizes consistent surround sound immersion aligned with its cinematic focus.

Sonos Arc Likes and Dislikes
Customer feedback for the Sonos Arc highlights its premium design, seamless integration with the broader Sonos ecosystem, and impressive virtual Dolby Atmos performance in smaller to medium-sized rooms. Many users on Amazon and Reddit appreciate its minimal setup and consistent software updates offering long-term support. Common positives include the sleek aesthetic, voice assistant support, and compatibility with Apple AirPlay 2. However, reviewers have raised concerns about its limited HDMI input options and the performance of Atmos without rear speakers. Some long-term users noted occasional lip-sync delays when paired with specific TVs. Another repeat critique is that expanding the system with subwoofers or satellite speakers can get expensive quickly, making the total cost less accessible for budget-conscious buyers.
Samsung HW-Q990D Likes and Dislikes
The Samsung HW-Q990D receives overwhelmingly positive customer reviews across platforms like Amazon, Best Buy, and Reddit. Buyers frequently praise its out-of-the-box immersive audio with dedicated up-firing and rear speakers, making it feel more like a home theater than a soundbar system. Commonly noted benefits include detailed Atmos separation, punchy bass from the included wireless sub, and reliable performance even in larger rooms. Nonetheless, complaints often revolve around minor app usability issues and firmware update bugs. A few users mention bulkier satellite speakers as difficult to place aesthetically. Long-term feedback consistently points to its plug-and-play nature and fewer reliability concerns over time, particularly for users heavily invested in Samsung TVs or Q-Symphony compatibility features.
| Common Praise | Common Complaints | |
|---|---|---|
| Sonos Arc | Elegant design, Sonos app, ecosystem integration, voice support | High expansion cost, limited HDMI ports, subpar Atmos without rears |
| Samsung HW-Q990D | Immersive surround out-of-the-box, strong low-end, high channel count | Bulky speakers, occasional firmware bugs, mediocre app UX |
