Hi All. 

So, Im adding 2 ceiling mounted X-LS Encore speakers to an existing 5.1 setup to create a 5.1.2 Dolby Atmos setup.  As suggested by Dolby here.  https://www.dolby.com/us/en/guide/speaker-setup-guides/5.1.2-overhead-speaker-setup-guide.html

Obviously I don't want to put additional holes in the encores if I can help it, and I'm sure distance from the ceiling is going to play a role, but Im not sure how much.  But I don't even know how to mount them to the ceiling.  And thats the part I need most help with.  Since this is a ported speaker, I assume I need it at least some distance from the ceiling.  I was thinking something like this: https://www.amazon.com/Pyle-PSTNDC31-Ceiling-Speaker-Mount/dp/B01HZMCSXM/ref=sr_1_4?ie=UTF8&qid=1490855451&sr=8-4&keywords=speaker+ceiling+mount

I could just mount the bracket to the top of the speaker, and fill it later with something if/when the speakers get re-purposed for some other use.  How bad an idea is this?

Any advice I can get from you fine folks would be greatly appreciated.

Patrick, this will work if you have a very tall ceiling.

I will be doing the same thing with 4 XLS speakers, but I had mine built without the ports. Are yours front or rear ported? If rear ported, you could plug the ports and then mount them closer to the ceiling. Dolby guidelines have them facing almost directly down, assuming a dispersion pattern covers the listening position. 

I like those mounts. Let us know how it goes.

Danny, my ceilings are 8 1/2' high.  Sounds like I need to keep looking?

Mine is 8 1/2 ' also.

Then mount a LGK 1.0 driver in the ceiling.

They probably won't see much power anyway. They are easy to mount as they are a light weight single driver.

Just keep the same box volume as the LGK 1.0 kit and port it using a small port and run it out the front.

I've already purchased and built the encore.  I'll have to find a way to make those work.

Put them in the rear.

I have a pair of the encores in the rear already. And those rears are the floor standing enclosures.

You could use a 7.1 system with the Encore monitors as surrounds and the towers as surround back speakers. Then you could put the LGK's in the ceiling. Provided you either have a 9 channel (7.1.2) amp or pre-outs for the main channels to a separate power amp and the ability to reconfigure the main channels.

Otherwise, you can experiment with distance from the ceiling until you get the head clearance and sound dispersion you like. If that ends up with them close enough to the ceiling you get undesirable port noise, you can plug the ports like Skiman suggested.

Since you want the speakers firing straight down, an easy way to experiment with distance would be to use a mount made from black plumbing pipe. You could mount a flange to the back of the speaker and another one to the ceiling then use different length nipples for spacing.

No idea how I missed skillmans post. I think that's the route I'll go.  Mine are rear ported and in the worst case I can plug them. Not that I know how to do that.   Hahahah.   Thanks for all the great advice.
