I have a standard 5.1 system.
I was thinking about an Atmos upgrade without much wiring/visual impact and took a look at this ones, they are also available from Dali.
You just place them over your front (large tower) speakers and they do upfire to the ceiling simulating Atmos-ceiling-speakers...
Did somebody have a good experience with such a solution? Looks like a marketing story rather that real atmos effect....
