ZDNET’s key takeaways

• Your listening room’s layout has a huge impact on your soundbar’s Dolby Atmos performance.
• Several audio features can improve dialogue clarity.
• Expanding your Sonos home theater can boost audio clarity and robustness.

Sonos’ webpages and popular reviews are full of specs, but real‑life factors such as placement, content format, room size, and furniture affect your soundbar’s output more than you might think. Below are three free ways to get the most out of your Sonos Arc, Arc Ultra, Beam, Ray, or Era 300.

1. Problem: Dolby Atmos doesn’t sound immersive

The reason: A lack of height

Dolby Atmos relies on height cues. In theaters this is achieved with ceiling speakers. Home soundbars use up‑firing drivers to simulate height, but they need space to work.

The fix: Increase the height‑channel volume

If your ceiling is vaulted or the space between the soundbar and TV is limited, the up‑firing drivers may struggle. In the Sonos app you can raise the volume of the height channels for the Arc or Arc Ultra to make them more audible.

Adding rear speakers (e.g., Era 300) expands the horizontal plane and provides an up‑firing tweeter for extra height effect, if your room can accommodate them. The Sonos Ray and Beam (Gen 2) lack dedicated up‑firing drivers, but their forward and side‑facing channels still broaden the soundstage. Among compact options, the Beam (Gen 2) offers the best performance.

2. Problem: Dialogue isn’t clear

The reason: Speech settings and bass overload

Dialogue clarity can suffer when bass dominates or when speech‑enhancement features are disabled.

The fix: Use Speech Enhancement, Night Sound, and adjust Loudness

• Speech Enhancement reduces bass and boosts mids where dialogue lives.
• Pair it with Night Sound for further bass reduction.
• Turn Loudness off; it can amplify non‑dialogue sounds.
• If needed, lower the bass response in the EQ settings (available in the Sonos app).

Rear speakers and a subwoofer (e.g., Sonos Sub 4) let the soundbar focus on mids while the sub handles low frequencies, dramatically improving clarity.

If you need to watch TV without disturbing housemates or neighbors, consider the Sonos Ace headphones, which receive the same audio format as the soundbar.

3. Problem: Something just sounds “off”

The fix: Re‑calibrate with TruePlay

TruePlay is Sonos’ acoustic tuning feature that measures your room’s size, furniture, and layout to optimize speaker performance. Run TruePlay whenever you:

• Rearrange furniture or speakers
• Add or remove rear speakers or a subwoofer
• Change the listening position

A fresh TruePlay calibration ensures the soundbar adapts to the acoustic characteristics of your actual room, not the idealized “model room” shown on the Sonos website.
