I am finishing a dedicated HT room, relative small room 17x12.5, I have a tray ceiling/soffit about 2 ft wide, wonder what size of recessed light would look good on my environment..

here are some dimensions:
the ceiling is 8'11" while the tray is 7'9" tall
plan to build a 10 inch riser near the back of the room.

should I use 4" or 6" cans?

Definitely not 6". Use 4" or even 3". I gather they all have to go in the 2' space around the tray?

No matter where you go. ... There you are.

yes. they are all in the 2' tray. agree 4" looks good,

now my next challenge is the 4" IC cans are still too bulky and it doesn't fit on one side of the tray as there is drain pipe occupying half of the 2' tray width.. so if I use the non-IC cans (smaller), I'll not be able to put the fiberglass insulation - how would I then fill the cavity then (otherwise, would there be resonance due to the hollow tray?)

thanks.

I have 4" cans in my room and I think they are perfectly sized for a small theater.

The best thing about a 4" can, is the fact that you don't have to pay the ridiculous premium for low-voltage IC fixtures.

I'm using 3" cans in my soffit. They were $10 each including the bulb.

Fill the parts between the cans. Or leave it out. If there is structural resonance, loose insulation isn't going to do much in the way of damping anyway.

It's perhaps not so much structural resonance as air cavity resonance. Anything sealed and hollow should have some absorption inside.

Can someone tell me why people put lights above their screens? Is it just for looks?

I don't have any above mine, but I wonder why would I need them at all?

I don't know of any fixtures that are sealed. For that matter, he could just leave some extra air gaps and call them resonators.

I was refering to the hollow areas within structures like a soffit. Not suggesting we fill our light fixtures with insulation.
