Though a nice touch, I do not think Sonos is in the business of producing such dedicated speakers. Most Sonos speakers up til now are multifunctional - to be used stand alone, in stereo set ups or in surround system.

Exactly what makes upfiring speakers in the front not a “true Atmos Experience” and yet upfiring speakers in the back is a “true Atmos Experience”?

Sonos please make some upfiring speakers to add to my system I have the arc and 2 gen 3 subs and 2 fives for the rear I am so happy with the products you make but need those upfiring speakers I know my customers would love to here there new computer demo with true Atmos Experience 

I have actually had quite a number of people pick up a sonos system Because I have demoed mine to them when they pick up there new computer 

Even without other upfiring speakers?

Yes it is still I think the best wireless speakers you can buy I  Used to have all Martin Logan speakers But The amount of wires is ridiculous I had a 11.2 system Which I miss very much but I do not miss the wires Plus I  Downgraded to a smaller home I heard that sonos is going to make rear  Multi directional five's witch I wish I could demo but a separate upfiring rear would be better I think for the people who spent a lot of money on the five's
