Overhead speakers for Atmos 5.1.2 system


Hey guys,

I'm going through a remodeling projecting and increasing my living room from 168sqft to 280sqft (vaulted ceiling - 11ft average height). So naturally, I'm also looking to figure out some ceiling speakers for my future home theater system and improve my standard 5.1 system to a 5.1.2 Atmos. Currently have B&W 803S (main speakers) + B&W HTM3 (center speaker) + B&W 805S (surround speakers) + Outlaw LFM1 Subwoofer ... and I'm looking for 2 overhead speakers to complete the Atmos setup.

I'm a little bit worried of the sound being heard outside of the house since I have no room above, so I was looking some ceiling speakers that come with their own built-in back box (Focal or Definitive Tech). So do any of you have any suggestions or experience with such an Atmos setup to recommend some ceiling speaker that keep me under the $1k budget per speaker?

Thanks for your feedback Brad. I actually did more research on my own and experienced two solutions with 4 ceiling speakers and I also concluded that I will go into that direction. I'll still stick with the Focal 300 ICLCR 5 model as it suits my needs well.
Why? You're going to have issues with clarity unless you use something like Trinnov. Have fun during the journey.
How is that quite rock?  Is it worth the money.  I looked onto years ago, I think it was 70 bucks a sheet back then.  I ended up doing 2 studed walls with insulation in both with 1 in air gap.  Works good.  
I actually did not used them so far, but they sell for $55 at Lowes these days, which makes them 4x the price of regular drywall for the same thickness.
