I didn’t get as much done this weekend as I had hoped. I ran 1.5” conduit for future proofing future HDMI updates. I was going to pull the existing HDMI cable and run it through the conduit but this would be unnecessary. I will just leave it in place and have the conduit empty. There is not much to show here. I ran four lengths of rope through the conduit that I can use to pull cable in the future. This took me about 8 hours, it was a pain.
I flipped the grilles and sprayed some filler primer, sanded flat, then sprayed epoxy. All the enclosures and grilles are now ready for paint after a quick sanding.
I press fit the trim rings for the Atmos speakers. These will provide a perfect round reference against the round enclosures. This will be covered with the grill but if I ever decide to remove the grill I still want them to look nice.
The trim rings were spackled in place
I also started buttoning up the wire installation. All wiring was complete so it is just a matter of terminating everything, repairing drywall, and sanding.
I say it was complete because I made an error. I was drilling a hole to run some of the signal cable and the cable caught in the drill bit. I ruined two coax runs and one cat6. Unfortunately I ran through my entire ream of both of these with the install so I had to order more cable. It won’t arrive until next week so I will have to hold until then (using Belden 1694a RG6 coax and Belden 2412 cat6+... in fact the speaker cable is also Belden, their cables are high quality IMO). I am also on hold with finishing the enclosures until the single stage paint arrives.
The only unknown is exactly how I will secure the speakers in place. I want to keep it simple but I don’t know exactly how I am going to do it yet. I am thinking I will push the boxes into the mounting location, temporarily mount a 2x4 underneath them on the ceiling (so they are guaranteed flush with the ceiling drywall, then build a simple frame above them out of 2x4s so the Atmos enclosure can be screwed into the 2x4 frame through the speaker hole.
Alternatively I could just glue a piece of plywood with a hole cutout around the speaker and then set them in from the attic, in this case they would just be sitting free, but with a wide plywood base.
I like the simplicity of the second option better but I think the first option will be more secure. Any other ideas or thoughts?
