Has anyone used this?

Well, for what? 

 

If a speaker was designed without internal damping, adding it will change the cabinet tuning, making the woofer "think" the cabinet is larger.  That will produce a ripple in its response at its lower limit and increase bass output a little below that lower limit.

Hi John. Replacing the existing foam in a set of CHorus ii.

I was wondering if it would benefit the upper soundwaves in the cabinet.

Not necessarily.  It can also work against the bass output and over damp.  Maybe extending but at a lower lower level but likely relative to the overall loss.  Different types of enclosure types will yield different results.

 

In general though I agree.  Use what was in there or test other damping material.  Everyone has their own hot buttons and maybe more damped bass, depending on position and room may suit you.

Thanks Pete.
