Not at all. Here's a better explanation from the website I got it from:
" this works in higher frequencies to reduce reflections by breaking up, diffusing the energy, decouples vibrations, and is a superb thermal barrier.The only place to limit the use is behind speakers, just use a patch 8x8" or so to break up the back wave, it is so effective more will just kill off the midbass response which is not what we want to acheive."
I've done cars with just dynamat, and the Z with both. It's by far better with the foam.
