I disagree. Foam designed for acoustical use is pretty much the same from manufacturer to manufacturer.
Thanks for agreeing with me on point 2.
Glad we agree on #2. I've never found foam to be overly useful on lower frequencies, say, below 300-400 hz and down.
Highs and mids its very useful, but I believe its really an addition type product, where you utilize other methods first, then fine tune iwht the foam.
That's just my preference, having owned several pro studios over the years.
As far as foam being the same from manufacturer to manufacturer, I'll have to disagree here. I have foam by mail in the attic, and I'm not going to use it. If I do decide to use any foam, it will be auralex specifically, because I know as a fact its fireretardant.
I know, as a fact, the foam by mail stuff isn't anywhere near as flame retardant as the auralex stuff. I proved it with a lighter. Held flame to the edge, and the flame didn't go out on the foam by mail product immediately, the same way the auralex did. That's the safety difference.
Squeezing the two foams with my fingers, they feel very similar, I'll agree, but the auralex does feel different. They weight the same for the same size and thickness, but the auralex feels like the individual foam cells are minutely smaller. Can I measure this? No, probably not. Just going by my thumbs.
But I weigh safety above all else. The fact that the foam by mail stuff that I have sitting in my attic, did not extinguish right away, will guarrentee I will not put one iota of the stuff anywhere near my studio.
