These speakers are clearly well designed.
However, there are obvious issues with this bouncy sound.
Placed on-top of a speaker they can interfere with each other.
There has to be loss for distance to the ceiling and loss for bouncing.
I don't think 6 dB is out of the question, so this speaker needs (at least IMO), 4x the power handling, not tested here.
It is reasonable to measure speakers, but up firing speakers are in the snake oil category.
Dolby Atmos is a marketing machine with very little regard to implementation.
For $$ you get the Atmos label. This cannot be argued as my ThinkPad has the Atmos logo, clearly ridiculous.
If mounted to aim at the listener, I'd give them a fine/good.
If mounted to bounce, then the wide dispersion is a negative. I'd give them poor because the concept is bad.
Bouncy sound for Atmos is where the product becomes all marketing and deserves to be called Crapmos.
