Anyone considering using upfiring speakers for Atmos? I’d recommend two things in order to get it right. If you’re not using an Atmos speaker by the same brand of your main speakers, try to get them up high enough where there is zero line of sight to the drivers while in the seated position. Also, during configuration of your Atmos modules (speakers), there’s a control function located within the menu where you tell your AVR how close you have them in relation to the ceiling. I have a Denon and it’s under Setup-> Audio-> Surround Parameter.
I hope this helps someone not willing to install speakers in / on your ceiling.
