B&W M-1 for Dolby Atmos?


I am upgrading my tv room. I currently have 5 B&W M-1 speakers and a B&W sub. My plan had been to keep these, get a new Atmos amp and a pair of ceiling mounted B&W speakers to achieve the Atmos set up.

On reading the Dolby website however, it refers to the use of “Dolby Atmos enabled” left and right speakers. I’m not sure what this means. I had assumed that the M-1 would be compatible, since it is passive, and the important part is an amp that is capable of providing Atmos delineated signals to each speaker.

Am I over simplifying this?

Thanks in advance.
