Arc, Sub Gen 3 and Era 300

What do you consider ‘systems’? If that is ‘speakers’, yes, they’ll all work together in a home theater setup.

In order to complete a full Atmos setup, you’d need at least one Sub. It does not have to be a gen 3.

Hi

I have now 1 Arc, and 1 Era 300. In order to get Dolby Atmos - is it enough to buy 1 more Era 300?

( do I must need Sub for Dolby atomos ?)

thanks

I think your use of the terms is confusing, but in order to use the Sonos Era 300 as a surround speaker for the Arc, you’d need a second one. Surround speakers are always a pair of speakers, never just one.
 

A Sub, or Sub Mini, would flesh out the sound, by reproducing the .1 part of either a Dolby Digital or Dolby Atmos signal. 
 

You can send Atmos to the Arc already, it will deal with the signal without surrounds and Sub as it stands right now. 

Hi

I have now set up with a pair of Era 300 and Arc.

with music , it’s really great listening experience but while watching movies/ Tv still seems surround sound is missing !!! Not sure whether it’s a fault from Sonos SW!
During watching movies or TV, in sw I can’t see the content show Dolby Atmos ( my tv doesn’t have eARC port). Also from Era 300 seems side twitters sound is not there , only rear sounds providing .

any suggestion or info can help to this limitation?

What does the Sonos app say you are receiving when you miss surround?

For TV viewing it is not necessary to use eArc to get Dolby Atmos. eArc is need for uncompressed Atmos, but most if not all streaming services use compressed Atmos form a Dolby Digital stream - that can be passed through HDMI-ARC.

@106rallye movies like  Avater 2”( from Apple Store ) , the content is Dolby Atmos supporting . When I am watching this on the app I have look on it but it showing “Dolby Digital 5.1” ! Why it’s not showing Dolby Atmos ?

regarding surround sound - on social media ( YouTube ) I have also found that claiming regarding era 300 is not providing side twitters effect during watching TV  which is also in my case I don’t get it as well from eta 300 . I am not sure whether Sonos should fix the issue via a new SW update!

Sonos could make it so 1 era 300 as a single rear surround solution but chose not to  like pairing two arc’s together as surround is also impossible limited by corporate interests i believe 

Laugh…right, they could have also set it up so a single PLAY:5 or Sonos 5 could have been set up as surround speakers….but you still wouldn’t get a ‘surround’ experience from a single point speaker. 

I think you’re not comprehending that ‘surround’ noises move, across the back of the sound field. They wouldn’t be moving if you had a single stereo speaker. They’d only come from ‘behind’, with zero effective movement to either ‘side’ of the sound stage. 

I do not think there are many suppliers using single rear surround speakers. If Sonos would allow this, they would lose sales (people would buy less speakers) and custumers would get sub opimal surround (probably losing Sonos even more sales).
