At present, I have the following products, in one room, presently consisting of two groups that was I believe bonded remotely by Sonos. The main purpose is for Home Theater purposes. I am currently able to maintain full fidelity including Atmos

 

I have, presented by relevant “group” 

_group 1_____

1 arc ultra ( connected via e-arc- into tv) ETHERNET 

2 era 300 ( rear surround )  (½ ETHERNET)

1 gen 4 sub (Ethernet)

__group 2_________

1 Sonos amp (connected wirelessly) (ETHERNET)

2 era 100 ( surround )

2 wired floor speakers (beside tv)

1 gen 4 sub (ETHERNET)

___group 3____ 

2 era 300 stereo pair. (ETHERNET) 

I purchased another amp because I thought it might be necessary for full fidelity to add the 300s as stereo but I wasn’t able to add it into the app I just had to pair them as a stereo set. I purchased $300 of cable to experiment if things are better and Sonos can bond all three groups… But I don’t know I am so frustrated at Sonos support, I just spent money because I couldn’t get consistent answers about anything.

 

I can still return the amp… do I want to keep it and use line in for the 300 on the ceiling upfront? I’m curious to see the new streaming box that’s coming out that has Atmos support and multiple HDMI… my brain is fried. but I got everything working consistently now the key was to originally start The two bonded groups before turning on the group era 300s… it works … but I want it all bonded

We have been over and over and over this many, many, many times.  You cannot bond more than 1 soundbar, 2 surrounds, and 2 Subs (or 1 Sub Mini) in a Home Theater setup.  Anything else you “add” to the room will be grouped, and thus will play a downmix of all channels (bad), will suffer a 75 ms delay (bad), and is NOT recommended by Sonos.

 

PS - If you need documentation that adding additional speakers to be grouped to a Home Theater setup is not recommended, see this link:

Moderator edit: We do not recommend this at all - it will likely sound bad with all channels coming from the “front” speakers.

I would also like to add that, Sonos has designed for a minimalistic clean look, while delivering the best audio possible in each from factor it manufacturers.

I feel that people who want, or need, this many speakers in a room to be satisfied with the sound, should consider looking at audio/video setups that are based around processors like this and this so they can configure and expand to a surround sound system as big as they wish.

I guess I should’ve read a few hundred more pages of forum posts. * Said with frustration ulterior reasoning

 

I was literally told by Sonos that with this amp I will be able to bond it all together. I want to scream. Maybe I should just return all nine of my Sonos units

Also, Sonos does not randomly Bond speakers nor Group rooms/zones.

Bonding applies to configuring for example a home theater setup wherein you have a Sonos soundbar that will send data to a Sub and/or surrounds via the Sonos hidden 5Ghz channel. The Bonding process can also apply when adding a Sub to a single or stereo pair of speakers.

Grouping applies to bringing two room/zones together to play in sync. Typically for music and is not recommended for Video as the audio will experience a 75ms delay.

Additionally you can have multiple rooms/zones in one Space. For example:

  • Room A Sonos home theater with soundbar, surrounds and sub
  • Room B In-ceiling speakers powered by a Sonos Amp

One last suggestion: You should consider placing your Sonos on WiFi unless there is some specific reason you need to wire components. I have 31 Sonos units all running on my Mesh network via WiFi.

Or maybe you should actually read the replies to your posts, because you’ve been told this information several times already in every thread you’ve started. 

I don’t know your ultimate expectations. Judging from your room diagram above, I don’t think that you should be attempting to use SONOS. I suggest that you hire a pro and install a traditional system.
