I was planning to just do a LED tape strip along the lower portion. At this point recessed lights would be tough to install, but not out of the question.
Based on my experience it doesn't work with UF. I compared swatches of UF and XD before purchasing and XD is definitely more porous that UF (see below). I have a Premier frame with 114.7" diagonal UF screen. I have two recessed lights behind my screen in the ceiling.
Here's what it looks like behind my screen (minus some speaker stands I built after I took the pic, but you get the idea.
Here's a couple of shots with only these two lights on behind the screen.
So you migtht be asking yourself - "maybe your lights aren't bright enough or they're positioned too far behind your speakers"
I pulled off one of my fabric panels and put a bright painting light under my left speaker shining right up the speaker stand and speaker face. Here's a pic. You still can't see them.
Now, maybe I'm not placing the light in the right spot, or I need more lights, but I was hoping to have the same effect as Youthman in my theater, but have been unable to reproduce. I believe UF just isn't porous enough to show light back through. It feels like a piece of spandex and I think the holes letting sound through are just too small to produce the desired effect. I was actually able to dig up my samples and took pictures of both holding up about a foot in front of my TV with a basketball game on behind it and full lights on in the room. You can clearly see through the XD, but not at all through the UF.
Maybe Chris can shed some light on things (pardon the pun) in a more technical way. My screen has been great so no complaints here about anything. Hopefully this helps.
