Era 100 added to existing surround setup

Ive had an Arc, Gen 3 Sub and a pair of Ones as my rear for surround.  I recently bought a pair of era 100’s to add as fronts (thus finally have living room surrounded all around), but they’re adding separately as stereo and don’t play with the existing setup.  Apparently I’m a moron with this App. Do I need to delete my setup and start over with all speakers??

You cannot add separate fronts to a Sonos Arc (or any soundbar ever made).  Soundbars already contain the front left-center-right in a single enclosure.  Some have claimed grouping a stereo pair to get pseudo “fronts” works, but in reality that is not recommended.  Instead of “fronts”, you actually get all channels, front left-center-right, rear surrounds, and Atmos height channels playing out of the grouped pair, all delayed by 75 ms, causing an echo effect, not to mention wrecking all directional and Atmos effects.

In short, more speakers does not mean better sound.

A surround Room consists of a soundbar in the front, two identical speakers or an AMP for the surrounds, and one or two (depending on model) SUB’s. Additional front L/R speakers are not supported.

If you Group the two Sonos Rooms they will play streaming sources in sync, the TV source will see the second Room slightly delayed causing an echo effect.
