That should work fine, yes.Regarding the cloud absorption, I was going to use our standard Roxul mineral wool here in Canada ( which has a density of > 2 lb/ft3 or > 32 kg/m3 ) covered in breathable fabric,
That's fine, since that's where your mids will be bouncing from... mostly. And at high angles off-axis from the speaker, you'll be getting mostly mids up there, rather than highs. But its also worth trying at least a couple of rays bouncing off the insulation surface, just to get a better idea of the big picture.so I was reflecting the rays off of the hard plywood (or MDF) lid.
You should be OK with that. Do you have the actual acoustic data for that product? Specifically, the coefficients of absorption at various frequencies? That would be useful.Should I use "lighter" or less dense insulation in the cloud in your experience?
