Hex, I'm already working with my new client, but you are absolutely not stepping on any toes. I agree that high-end bookshelf size speakers make sense unless it's for a system in a very large space that needs to play very loudly.

I got your email, and I'll be glad to help you privately on a consulting basis. So no need to continue here, I'll reply to your email now.

Wow, great post Hex! I was serious about you knowing more than me. I haven't kept up over the past ten years with the current understanding that GFR is the true arbiter of absorption rather than density. I'm glad you're here to help!

Which of the three? Ask Andre! Or if he says they're all the same, go with what's cheaper or easier to get.

Hexie, you're doing fine! I was just pointing out that whatever Andre says should be taken seriously.

Are you saying I need to study more before giving advice? OMG No! At this point you probably know more than I do.

I'd never compared different thicknesses scientifically, but I know that it doesn't matter much. A large trash bag would be fine.

It's always better to start a new thread for a new topic. But the short answer is yes, though most people use thin plastic instead of aluminum foil.

Andre is a genuine expert. You don't need to ask anyone else.

In all honesty, I'd go by what Andre says. I know that 6-inches of ANY rigid insulation does a great job. But Andre follows the details more closely than I do. So do whatever he says. I am serious.

Yes, that will be excellent.

If I use OC 703-FRK (three 2" thick panels to make 6"), I would have the FRK foil layer three times, the first on the front, the second 2" from the front, and the third 4" from the front. It's important to remove the FRK facing from all but the one layer that faces the room. Or use FRK for that layer and plain 703 for the other two closer to the wall.

As I recall cork absorbs about 30 percent, though the frequency range depends on its thickness. So it will not be too absorptive. But the front wall is probably the last place to worry about, other than for bass traps, because your speakers send most of the sound the other way.

This is a lot to take in, but I think the plot just below your photo above is more modal than boundary. Your dashed lines don't really follow the peaks and nulls correctly. For example, the bottom green null at 60 Hz is more likely the same as the orange null directly above. And the orange null at 40 Hz simply doesn't exist at the green distance. Modal peaks and nulls also change with position, so a peak at one location or frequency can be a null at another.
