🔧 What You’ll Need:
- 1x Sonos Arc (main soundbar with Dolby Atmos support)
- 1x Sonos Sub (optional but highly recommended for bass)
- 2x Sonos Era 100 or Era 300 (for rear surround channels)
- Sonos app (iOS or Android)
- Wi-Fi network
Step 1: Place the Sonos Arc
The Sonos Arc is your front soundstage—this replaces your center, left, and right channels.
Placement tips:
- Center it directly under your TV (wall-mounted or on furniture)
- Ensure it’s not blocked—especially the upward-firing Dolby Atmos drivers
- Use the Sonos Arc wall mount if needed
📌 Connect the Arc to your TV using an HDMI eARC port to support Dolby Atmos.
Step 2: Add the Subwoofer
While the Arc has decent bass, the Sonos Sub dramatically improves the experience by handling low frequencies.
Placement tips:
- Place near the Arc, but not in a tight corner or under heavy furniture
- It can sit upright or flat on its side
- Avoid placing it directly behind the Arc
In the Sonos app:
- Go to Settings > System > Arc > Add Sub
- Follow the prompts to wirelessly link it
Step 3: Set Up Era 100s as Rear Surrounds
The Era 100 speakers provide rear-channel audio, turning your setup into a 5.1 or Dolby Atmos surround system.
Placement tips:
- Place one behind and to the left of your main seating area, and one behind to the right
- Position at ear level when seated, ideally on stands
- Keep at least 2–3 feet of space between the speaker and the wall for better acoustics
In the Sonos app:
- Go to Settings > System > Arc > Add Surrounds
- Select your Era 100s and assign them as left and right surrounds
✅ Era 300s are more immersive for Atmos due to their spatial audio design. If you have them, they’ll provide height effects from the rear too.
Step 4: Tune with Trueplay (iOS Only)
If you have an iPhone or iPad, use Sonos Trueplay Tuning:
- Go to Settings > System > Arc > Trueplay
- Follow the instructions to walk around the room with your iPhone
- The system will automatically optimize EQ for your space
📱 Trueplay is currently only available on iOS. If you don’t have an Apple device, consider borrowing one just for this step—it’s worth it.
Step 5: Test and Fine-Tune
- Play Dolby Atmos content from streaming platforms (Netflix, Disney+, Apple TV+)
- Use the Sonos app to adjust individual speaker volumes
- Set night mode or speech enhancement as needed for different content
Final Thoughts
This setup gives you a wireless 5.1.2 Dolby Atmos surround system that’s:
- Minimal in wiring
- High-quality in audio
- Easy to control via app, voice (Alexa/Google), or TV remote
It’s ideal for medium to large rooms and can expand later with more Sonos products.
