Detailed Sonos Arc Vs Arc Ultra Feature Comparison
Channels and drivers
Sonos Arc is built around an 11‑driver array in a 5.0.2 configuration, giving you front LCR, side dispersion and a pair of up‑firing units for Atmos height effects. It already delivers a convincing bubble but leans heavily on virtualisation for rear and extra height information. Arc Ultra jumps to a 9.1.4 layout with 14 drivers and 15 amps, significantly increasing discrete surround and height coverage. This produces more precise object placement, stronger rear wraparound and a fuller dome of sound in medium‑to‑large rooms.
Bass and low‑frequency handling
Arc uses eight midwoofers to handle both midrange and bass, which sounds full at moderate levels but can feel lean for movie LFE unless paired with a Sub. Its crossover to an external Sub is set relatively high, so some male voices and mid‑bass energy sit awkwardly between bar and sub in certain rooms. Arc Ultra introduces the flat “Sound Motion” woofer plus six midwoofers, delivering roughly up to double the bass output in a similar chassis and allowing a lower 70 Hz crossover to a Sub. Result: deeper slam, tighter integration and cleaner vocals.
Immersion and Atmos performance
With Arc, Atmos immersion relies on two height drivers and clever psychoacoustic processing, creating a good 3D effect when ceiling and seating geometry cooperate. Overheads register, but side and rear imaging can collapse toward the screen in open‑plan or asymmetrical spaces. Arc Ultra’s extra drivers and revised layout steer effects more accurately around and above the listener, expanding the soundstage horizontally and vertically. Height moves, fly‑overs and ambient beds feel more continuous, approaching what you would expect from a compact separates system, especially for Atmos movies and games.
Dialogue clarity and midrange
Arc already delivers very clear centre‑channel reproduction, tuned with input from film mixers, and features Speech Enhancement to lift dialogue in noisy scenes. However, its shared mid/bass drivers and higher bass crossover can occasionally thicken lower male voices when used with a Sub. Arc Ultra’s driver split, extra tweeters and lower crossover give more headroom and separation in the vocal band. Dialogue sits more firmly locked to the screen with better articulation at low volume, while the new adjustable Speech Enhancement lets you fine‑tune clarity rather than simply toggling a fixed boost.
Processing power and platform
Sonos Arc runs on an older hardware platform that still copes well with Atmos decoding and streaming, but leaves less overhead for future codec or feature additions. Arc Ultra updates the internals to a quad‑core A55 CPU at 1.9 GHz with 2 GB RAM and 8 GB storage, similar to the latest Sonos speakers. This extra processing headroom supports more complex beamforming, Sound Motion woofer control, refined Trueplay analysis and advanced features like TV Audio Swap to Sonos Ace. It also gives more margin for future firmware updates and format tweaks.
Formats, connectivity and latency
Arc supports Dolby Digital, Dolby Digital Plus, Dolby TrueHD and Dolby Atmos via eARC, plus multichannel PCM, but omits DTS decoding. Networking is limited to Wi‑Fi 4‑class radios without Bluetooth audio streaming, pushing everything through TV HDMI or network services. Arc Ultra keeps all of Arc’s Dolby and PCM capabilities, adds DTS Digital Surround decoding and Atmos Music, and upgrades wireless to Wi‑Fi 6 plus Bluetooth 5.3 for direct streaming. This gives more flexibility for non‑eARC TVs, gaming sources and mobile playback, and improves robustness in congested Wi‑Fi environments.
Room tuning and app features
On Arc, Trueplay tuning (iOS‑only in full form) measures room response and adjusts EQ, with basic bass/treble controls and simple on/off toggles for Night and Speech modes. The system works, but tuning options are relatively coarse and Android users are constrained. Arc Ultra introduces a newer Trueplay generation that works across more devices, with finer control over how the bar balances bass, dialogue and surround in challenging rooms. Combined with its extra drivers, this allows more precise tailoring for reflective Indian living rooms, open layouts or asymmetric TV placements.
TV, headphones and ecosystem
Both soundbars integrate tightly with the Sonos ecosystem, support Apple AirPlay 2 and offer touch controls, app control and voice assistants, though Google Assistant support is being phased down on newer hardware. Arc provides standard eARC/ARC operation but cannot offload TV audio to headphones. Arc Ultra adds TV Audio Swap to Sonos Ace, letting you move TV sound from the bar to headphones with spatial audio and head‑tracking for late‑night viewing. As Sonos’ new flagship, Ultra is also the assumed focus for future ecosystem features and multi‑device workflows

Sonos Arc Ultra – likes and dislikes
Customers praise the Arc Ultra for its huge, room‑filling Atmos soundstage, with noticeably stronger bass and more precise height and surround effects than the original Arc. Many like the cleaner dialogue, improved TV Audio Swap with Sonos Ace and the convenience of Wi‑Fi 6 plus Bluetooth streaming from phones. On the negative side, reviews frequently mention the high price, especially when adding a Sub and surrounds, plus some frustration with Sonos app changes and account requirements. A few users also note that optimal Atmos performance still depends heavily on room shape and TV eARC reliability.
Sonos Arc – likes and dislikes
Arc owners consistently highlight the cinematic soundstage, clear dialogue and strong Atmos immersion from a single bar, especially compared with TV speakers and many rival soundbars. Users like the sleek design, easy setup and reliable streaming through the Sonos ecosystem, along with solid music performance for a living‑room all‑rounder. Criticisms focus on bass that can feel light without a Sub, the premium pricing once you build a full 5.1.2 system, and limited HDMI inputs. Some customers also complain about reliance on the Sonos app, occasional software updates that change behaviour, and lack of DTS on older firmware.
Sonos Arc Vs Arc Ultra Common praises and complaints
| Speaker | Praise | Complaints |
| Sonos Arc Ultra | • Big, immersive Atmos sound with stronger height and surround presence. • Deeper bass and clearer dialogue, especially at lower volumes. • Modern features: TV Audio Swap, Wi-Fi 6, and Bluetooth streaming. | • Very expensive, especially with Sub and surrounds. • App and ecosystem lock-in; some dislike Sonos software changes. • Atmos impact still room-dependent; needs good eARC setup. |
| Sonos Arc | • Cinematic upgrade over TV speakers with convincing Atmos from one bar. • Clear dialogue and good balance for movies and music. • Sleek design, simple setup, and strong Sonos multiroom integration. | • Expensive once optional Sub and surrounds are added. • Heavy dependence on Sonos app; some app frustrations. • Bass can feel light without Sub; lacks DTS on older setups. |
Use Case Analysis
Choose Sonos Arc if
- You want a big upgrade from TV speakers for movies, sports and OTT without going fully “flagship”.
- Your room is small‑to‑medium, you sit fairly central, and you are okay adding a Sub later if you want more bass.
- You value the Sonos ecosystem, clean design and simple setup, but do not need Bluetooth, TV Audio Swap or the absolute best Atmos bubble.
Choose Arc Ultra if
- You are a movie or gaming enthusiast who wants the most immersive Atmos stage, with stronger rear/height cues and noticeably deeper bass from a single bar.
- You already use or plan to buy Sonos Ace headphones, and features like TV Audio Swap, Wi‑Fi 6 and Bluetooth streaming matter for daily use.
- Your room is medium‑to‑large and you are comfortable paying a premium (possibly with Sub/surrounds) for reference‑level performance.
Skip both if
- You mainly watch casual TV at moderate volume, sit very close to the screen, or your space is too small or acoustically poor to benefit from advanced Atmos.
- You do not want to lock into the Sonos ecosystem or rely on an app, or you need multiple HDMI inputs and DTS features that cheaper AVRs or other bars offer.
- Your budget is tight and you would rather prioritise a balanced bar‑plus‑sub combo or a basic 5.1 AVR package at a lower overall cost.
