Room doesn't exist anymore. - Most likely incorrect anyways.

If it's not too much trouble, do you mind showing REW sweeps and the RT60 graph with Topt traces? I'm wondering about the effects of foam on the reverb time.

The RT60 graph will show the effects of your treatment on reverb linearity across the spectrum. That's mostly what I'm looking for. No need for a before/after.

There's a speaker/room acoustics subforum. And a book thread in the newbie subforum. A list of good material would be welcome in either, I would think.

I haven't used REW before so hopefully this is what you're looking for?View attachment 54044

Yup, exactly that. I was curious what that much foam would do at the listening position. Seems like 50ms reverb at 20kHz, gradually sloping up to 100ms at 400Hz, then going wild below that. Not exactly linear, but more controlled than I thought. Thanks for taking the time to measure and post
