It seems that Sonos is preparing new models for its Play: 5 the Sub which is a wireless subwoofer and the Playbar. These speakers would add according to some rumors Dolby Atmos support and all this would come for this june. The company continues to improve its speakers and despite all the problem with the coronavirus pandemic, it does not resist working and increasing the options of its spectacular speakers, so we must be attentive to possible movements.
In this case it is a rumor and there is nothing confirmed but Sonos wants to implement Atmos surround sound to its speakers and it is that many of the users who have these speakers have been claiming this technology for a long time. Also the Playbar has not been updated since 2013 and lacks support for many modern technologies such as AApple's irPlay 2, HDMI Arc, Alexa, and Dolby Atmos. The powerful Sonos Sub subwoofers were released in 2012 without receiving any updates since then and the Sonos PLAY: 5 was last updated in 2015.
All this suggests that Sonos could be thinking of a renovation of these speakers to implement new technologies in them and already added Dolby Atmos support. Sonos is synonymous with audio quality and in this sense it has that could improve some of its speakers this year. We will see if it is fulfilled and while we must take advantage of the discounts that it is offering precisely in these models if you are not very "demanding" with the purchase of the latest model, in this case there is 150 euros discount in them it may be to remove the stock in warehouses.
