I wonder if changing the distance settings (setting them higher than they actually are) in the processor would be a possible solution to low ceilings.
Changing distance settings would change timing and (similar to changing gain settings) would throw off the correct balance of surround sound.

Re: JBL 8320 for Atmos ceiling speakers?

Although you're at the limit of a couple of the Dolby guidelines, I think your strategy is a good one. The 8320 will be nicely matched to your other speakers, which is always good. Mount them as planned and let your AVR do the calibration. I don't suggest changing the level or distance settings on the overhead speakers once the room correction has been done. It sounds like your listener level speakers are in a good position given the dimensions provided. I think your top fronts are far enough from the MLP - 8ft+ (line of sight) based on my estimates. You may end up wanting to angle them toward the MLP a tad. I'd say if the AVR compensates with an extreme level boost on those, make use of the built-in 20 degree mounting angle to aim them. You may also notice localization from the top rears, in which case I'd say it would be ok to manually dial back the level on those just a bit.

Looking forward to hearing your impressions once you're up and running. I'm sure I missed it somewhere... what AVR are you using?

I am currently just using a Krell Showcase 7.1 preamp until I find a AVP with balanced outputs (true differential), HDMI 2.0, HDCP 3.2, Atmos, and DTS-X. I figure it will be sometime next year before I can complete the jump. For the time being I am just getting the amp, and speakers all setup. I also will have to decide if I want to add another DDRC-88A or just eq the Atmos channels.

I can't wait to get the setup tuned with the DDRC-88, and the new JBL surrounds.

Re: JBL 8320 for Atmos ceiling speakers?

Did you use the 8320 , i have these as rears and they are working very well. very good dynamics and extend very low to 65hz at -3b. they have good directivity index so I think they will work very well. I see many people use the volt 10lx or 6/8lx but I doubt that they will be much better they provide more dispression so in case you have a few sitting row it may be a better speaker. I am being lazy as I have done a lot of DIY and can't be bothered with more speaker DIY.
