All of them, or any of them, can be grouped with your Beam and One. 

Hi ​@moore63 

Welcome to the Sonos Community!

To expand a little on ​@Airgetlam’s answer, all the speakers you mentioned will work with your existing speakers on a system together. However, only Era 100s are compatible with Beam Gen 1 in terms of being used as surround speakers for a Home Theatre setup.

I hope this helps.

Edit: Added that Era 100s are supported as surrounds for Beam Gen 1 (see below).

You need two of the same model speakers (but not portable models) to use as surrounds. They could be two Ones, or two Era 100’s or two Era 300’s. 

Hi ​@nik9669a 

Era 300 will not work as surrounds for Beam Gen 1, but will for Beam Gen 2.

Edit: Changed “Era models” to “Era 300”.

Era 100 is a compatible surround speaker with a Beam Gen 1.

Apologies - not sure how I missed Gen 1! 

Hi ​@Mr. T 

Yikes!

Thank you - I was looking at the internal docs for Era 300 and presumed Era 100 was the same. I have corrected my post above.

That’ll teach me 

Hi ​@nik9669a 

No worries - we all make mistakes, as I have just aptly demonstrated 

It was a much appreciated error!
