Nope. That stuff forms a solid, and provides practically no acoustic absorption at all.
It's great for filling dead air spaces, but be careful not to use too much. I've used it in various designs over the years to fill dead air spaces. I also use it to protect the corners of midhorn flat pack kits. I put the panels in a large plastic bag, set them in the cardboard shipping container, then spray in that stuff around the edges. Works great as a foam-in-place shipping filler material. But again, it's not any good for acoustic damping material, not at all.
Stick with R13. Don't go with any of the other stuff people sometimes go on about. Just get a few rolls or R13 and get after it. You'll have itchy arms for a day, but it'll go away. The speakers will perform better with the R13 than anything else you can find.
