Will 2 play 5's Work with playbar? Or did I make a mistake?

Despite the technical incompatibility, a pair of Play5 as surround speakers would be an overkill.

sound right, but if has the possibilities, then that would be more flexible, isn't it?

I read somewhere else that the issue is because the play 5 is old and doesn't have 5GHz wireless... If this is the case, when doesn sonos plan to update the current play 5's to meet the requirement and if my speakers were all wired (ethernet connected), this should cancel the need for the faster wireless? I was just looking to buy a second play 5 but looking at these threads really makes me unsure if I want to invest in a product that is already outdated... I'd probably get the play 3 or 1 just to find out that the next feature they release isn't compatible.

One of my setups consists of a Playbar and a grouped stereo pair of Play5 
(i don't care much for surround sound). The Play5s add the depth and base to make this all around a great listening experience.

In this setup, i do not experience sync issues whatsoever. Dropouts and distortion are usually caused from WiFi interference, routing issues, and daisy chained components that utilize the inbuilt switch in the Sonos components and add network traffic to the SonosNet.

Might be worth to submit diagnostics immediately after you experience the sync issue and to contact Sonos. Their great support team can help you to sort this out.

I don't disagree Peng!

If anybody wants to modd the Play5, the public FCC records for Sono's components can be found here http://fccid.net/search.php?cx=partner-pub-0545639743190253%3A4869533996&cof=FORID%3A10&ie=U...

I personally think the Connect:Amp, Connect, and Play:5 are getting a little long in the tooth and wouldn't be surprised to see updated versions.... in next few years.

How many surround speakers can you add.... Can a 12.2 home theater system be created with Sonos components ???... i.e (Sound bar, 2 subs + 7 surround speakers)

No 5.1 is the max. I mean you could add other stereo speakers but that is all they would be stereo speakers.

Then what's so special about Snos's home theater compared to Bose?!!!... even the LG guys have a 9.1 surround home theater that's a blast with 25% the cost of Sonos. I am sincier in my question and i really hope to receive an answer.

Bose and LG's offerings are not wireless, and they are not part of a multi-room audio system that allows for perfectly synchronized audio in up to 32 units all around the home.
