Hi!
I got 489x537x253cm living/listening/cinema room, which means my 2 floorstanders on the longer wall stand pretty close to it (~20cm), and the L shaped couch stands pretty close to opposite wall (Probably that's why the ~35Hz rom mode is so huge - but this one is not my biggest concern of course)

With some luck I will squeeze around 7 pcs of 100x60cm/ (16cm/6.3" thick) absorbers in some corners of the room (for biggest air gap)
As I don't have a lot of space. I'm thinking about making some more 100x60cm absorbers for the ceiling (I fill fit only 10cm/4" thick absorbers + 8-10/3-4"cm air gap behind due to projector light)
Does it make sense to make the skinny ones for the ceiling?
If I make some. Whats the priority of ceiling locations? Should I focus on first reflections, or places over the speakers/ listener?
I'm thinking (have perfect space) about 2 Helmholtz Resonators - but I'll come back to it later, after the first part will be done.
Is it a good idea/plan at all?

10cm absorption plus 10cm air gap isn’t really skinny and brings you effective absorption down to around 100Hz. Reflection areas benefit from diffusers, more so than absorbers. Spreading absorption panels generally is preferable to concentrating them. Absorption panels near corners generally are more effective than panels in the center of surfaces.
