Not so fast. Quoted from the Denon manual:
When I had my speakers set to Atmos ceiling speakers, the receiver didn’t have the option for Auro 3-D, only Auro 2-D. Now that I changed my speaker configuration to the Dolby Upfiring speakers, the Auro 3-D option has returned. I guess, Auro is okay with a diffused but not direct sound while using Atmos speakers. Yes, I’m getting sound out of all four of those speakers and it sounds fantastic with two and four channel sources. I need to try it with 5.1 but so far I like it better than the more echo effect of Dolby Surround and DTS X: Neural. Auro stays much closer to the original source sound while expanding on it. I thought I’d have to move my speakers way up on the wall like the below illustration but I won’t have to now.

So, to answer your original question, maybe configure your speakers to what Auro recommends?
Side note: I’m listening to Fleetwood Mac’s Sugar Daddy right not in Auro 3-D and I’ve never heard that car horn in all my life! :yikes
Gene,
Play around with Auro and tell us what you think.
