Sonos Arc Ultra and just purchased Era 300


I have owned the Arc Ultra for a few months and I always planned on building up to the full surround kit as i could afford. So today, I pulled the trigger on the sub mini and a single era 300 (i cant afford 2 right now, ill add the second one next month). Is is true that you need to have a pair of era’s to add them as a surround speaker? I have tried adding it to my system 30 times, factory reset everything, reinstalled the app, firmware updated on my router...literally every newbie troubleshooting step i can think of, thats why I need an expert to step in.

 

My system is all set up with the arc ultra and running perfect, when I add the Era 300, no matter what I choose, it adds its own room everytime. So say my arc ultra is set to “Den”. when i add the era to den it creates a “den 2” everytime. I cant fix it. It also wont run as a surround speaker. I just have to enable them both as seperate speakers playing the same sound. So its not surround sound, its just 2 speakers near each other playing the exact same sound channel. Super headache inducing. Please help!

You can’t just add one surround speaker. It has to be two Era 300s.

As written you need 2 Era 300 to add them to your Ultra
( They must not be set up as a pair, as you add one at a time)

You can add your Sub mini to your Ultra or your Era 300.

If you want to make it easy for yourself then add your Mini to Ultra, use your Era 300 in another room. When you get your second Era 300 you set it up in its own group. Then the SONOS App will ask you if you want to add your Era 300 as surround otherwise you can go into your App click on Ultra and add them.

Skip the Sub mini, two Era 300 will be massive improvement for movies. Safe a bit for the non-mini sub
