When it comes to improving your TV's audio, soundbars represent one of the most popular and practical solutions. Today, we're comparing two distinct options: the premium Sonos Arc
($564) and the mid-range Samsung HW-B550D
($178). While both aim to enhance your TV audio experience, they take notably different approaches.
The soundbar market has evolved significantly in recent years, with features like Dolby Atmos and smart connectivity becoming increasingly common. Released in 2020, the Sonos Arc
represented a significant leap forward in soundbar technology, introducing upward-firing speakers and advanced room correction. The Samsung HW-B550D
, while more recent, takes a more traditional approach focused on core audio performance and value.
Both soundbars prioritize clear dialogue, but through different methods. The Sonos Arc
uses sophisticated digital signal processing and dedicated center channel speakers, along with a Speech Enhancement mode that can be activated through the Sonos app. This technology actively identifies and boosts dialogue frequencies while maintaining overall audio balance.
The Samsung HW-B550D
takes a more straightforward approach with its dedicated center channel speaker, which proves surprisingly effective for its price point. While it lacks the advanced processing of the Arc, its Voice Enhancement mode does a commendable job of lifting dialogue above background sounds.
Here's where the price difference becomes most apparent. The Sonos Arc
features genuine Dolby Atmos support through upward-firing speakers that bounce sound off your ceiling to create a dome of sound. This creates a truly immersive experience, especially in rooms with flat ceilings between 7 and 14 feet high.
The Samsung HW-B550D
uses DTS Virtual:X, a digital processing technology that simulates surround sound from the front-firing speakers. While this can't match true Atmos performance, it does create a surprisingly engaging sound field that extends beyond the physical soundbar.
Interestingly, the Samsung HW-B550D
has an advantage in bass response out of the box, thanks to its included wireless subwoofer. This provides immediate impact for movie explosions and music bass lines. The Sonos Arc
relies on its integrated woofers, which provide clean but less impactful bass. However, the Arc can be paired with the Sonos Sub (sold separately) for truly outstanding bass performance.
The Sonos Arc
shines in the smart feature department. With built-in voice assistants (both Alexa and Google Assistant), AirPlay 2 support, and WiFi connectivity, it functions as both a soundbar and a sophisticated smart speaker. The Sonos app provides extensive control options and integration with music streaming services.
In contrast, the Samsung HW-B550D
focuses on essential connectivity: Bluetooth, HDMI ARC, and optical input. While this means fewer features, it also results in simpler setup and operation.
For serious home theater enthusiasts, the Sonos Arc
offers several advantages. Its Dolby Atmos support creates a more cinematic experience, and the Trueplay room correction technology (iOS devices only) optimizes sound for your specific room acoustics. The Arc's ability to reproduce subtle details in movie soundtracks is impressive, though it benefits significantly from adding a subwoofer for the full home theater experience.
The Samsung HW-B550D
provides solid movie performance, especially considering its price point. The included subwoofer helps deliver impactful explosions and sound effects, while the center channel ensures clear dialogue. While it can't match the Arc's sophisticated surround effects, it provides an engaging experience for casual movie watching.
The Sonos Arc
excels at music playback, delivering detailed, well-balanced sound across various genres. Its integration with streaming services and multi-room capabilities make it particularly appealing for music lovers. The sophisticated signal processing helps create a wide soundstage that works well for both background listening and focused music sessions.
The Samsung HW-B550D
handles music competently, with its subwoofer providing good bass response for electronic and rock genres. However, it lacks the refined midrange and sophisticated processing of the Arc.
When considering value, it's important to look beyond the initial price difference. The Sonos Arc
represents a significant investment but offers future-proofing through regular software updates and expansion options. Its smart features and multi-room capabilities might replace the need for separate smart speakers.
The Samsung HW-B550D
provides immediate full-system functionality at a much lower price point. While it lacks advanced features, it delivers solid performance for basic TV and movie watching needs.
