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

User67513, You were given incorrect information on the phone. Please accept my apologies for that. The PLAY:3 is the only player unit (not counting the SUB) that can be paired with the PLAYBAR. Once again, I apologize for the inaccurate information relayed to you on the phone. John
Has anyone at Sonos read through all posts in this thread?

I'm pissed! Just purchased two Play 5's and a Playbar from future shop. They didn't have a sub in stock so I was going to add one of those at a later date. Sales guy at future shop told me the play 5's could be used on their own for listening to music, or be combined with Playbar and sub for surround sound. Obviously this is not the case. I'll be returning these items tomorrow. I had great expectations and hopes for the sonos system but feel I've been misled by both sonus and future shop. I'm not a happy camper.
You can use either Play:3's or Play:1's for surround.  Costs less and gives you about the same experience.  And while I can understand your misgivings about the misinformation supplied by Future Shops, why would you ever feel "misled by Sonos"?  They certainly never state in any literature that a Play:5 can be used for surround sound.  Matter of fact, right on the "Home Theater" information page it states:

Get full 5.1 surround sound with a PLAY:1 or PLAY:3 pair.Complete your home theater with a PLAY:1 or PLAY:3 pair as rear speakers. They’ll deliver deep, richly textured sound, and your movies and music will thank you.

Emphasis mine. 

Hi Gabbe. As Jgatie's response implies, it makes no difference whether or not Sonos has read this thread. The Play:5 is technologically incapable of operating as surrounds with the Playbar, which is why Sonos has never, ever suggested that it could be so used.

I'm more p*ssed off.. I've been slowly adding to my Sonos collection over 2 years with two play 5's, a 3 and a 1 and a connect, and just recently added (yesterday) a playbar to my pair of 5's to find out they are not compatable, WTF! This must be a joke. Sonos can't do this surely? This defeats the object of a same brand wireless system. I'm now thinking should I take it back and get a Samsung surround soundbar for half the price??! Not a happy customer..

Sonos have never claimed the 5's could be used as rear speakers. They are also total overkill for that purpose. I would suggest you buy another play 1 to make up a pair then you can swap one play 5 in place of the original play 1 - you then have a 'spare' play 5 to use somewhere else 😉 I should add, the reason a 5 cannot be used is because it does not have the necessary wireless capability (5 ghz). I do think however they should allow for them to be hard wired as rear speakers in the same way as the connect amp.

Had the same problem but somehow was able to work it out by pairing the living room configuration with the Tv's Playbar and then setting the volume for each configuration. It's not perfect as it does not really works as real surrounds but it works.
Sorry for the mistakes, as I'm not a native speaker. I hope I helped you guys.

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.

We don't have any plan or news available for an updated PLAY:5 with 5GHz support or setting up a way to add it as the surround for a PLAYBAR. As mentioned here, aside from the technical limitations, the audio profile out of the PLAY:5 would very likely overwhelm the PLAYBAR unless it was highly limited. 

5GHz is only used for bonding Sonos components with the PLAYBAR in the surround setup. The PLAY:1 for example, has both 5GHz and 2.4GHz. It uses the 2.4GHz for all communication with Sonos components or your home network except for when you want to bond it as rear surround speakers with the PLAYBAR.

If 5GHz is necessary for surround, then why is the sub not mentioned anywhere for having it?

The sub has 5GHz.
