Atmos crossover

[bruin62]

i bought a pair of atmos up firing speakers to try out, audyssey set the crossover at 200. The speakers did nothing to improve my setup so I returned them . So now I placed speakers on the ceiling pointing down this seems to work a lot better. But audyssey set the crossover at 60Hz since these speakers on the ceiling are used for atmos effect should they be set to 200Hz ?

No, the 200hz crossover is because you had them configured as upfiring speakers, Dolby sets those parameters to aide in reflection.

Got mine crossed over at 80hz with no issue. On ceiling speakers are no different than any other speaker in your system in this regard.

Thanks for the info I wasn't sure why it would be at 200Hz

Generally its due to the detected f3, would assume the reflection aspect would have a bit to do with it....

Yeah, this. The upfiring config uses a different XO point because of the way the reflected sound is implemented. Apparently controlled directivity isn't very good below 200hz. Kinda cheesy imo.

So the avr is told these are upfiring atmos speakers? Haven't set one up so wondering how this works....

Yep. It's in the audyssey setup menu. It's kinda like setting up an older avr for PLIIx/z, telling it what/how many speakers are where.

Interesting. Is 200hz the only choice if you tell it you have upfiring speakers? Does it matter front, rear, middle or whatever choices are for Atmos?

Iirc I've seen down to 90 as a choice, but it seems the f3 of most modules is 120 or higher. Not a global setting for enabled speakers.
