Polyfill placement question in monitor speakers.

I have a pair of Acoustic Energy AE-2 speakers that I am refurbishing. I had to remove the poly-fill batting while working on them and never thought to make note of where the poly-fill was originally placed. Now I have to put it back in.

I am wondering if there is a most beneficial area to place the poly-fill. Behind the mids? Around the ports? Pack the tweeter area? Really have no memory of where it was before.

These speakers have 2 mid drivers one tweeter and 3 ports. I am only putting back in what came out. There is not a ton of it so it does not fill the entire space. In fact I'd say there was only about as much to fill 1/4-1/3 of the volume.

These are excellently designed monitors and I'd like to have the damping working as designed.

I'm pretty sure this is Acousta-Stuff (how does one know?) unless they didn't make that in 1987.

These are pretty brilliant speakers. I'm probably not going to go the route of making obtuse changes.

I'd still like to find more about how/where this was dispersed. In the meantime I'll try to evenly fill the cavity.

Thank you Mijostyn

This is helpful! But did you mean decreases the size of the enclosure? From my limited understanding the mass of the batting subtracts from the void of the enclosure... the more fill added the less air there is in the space.

I know that Proac speakers limit the port flow with straws and such to increase box resonance... I’d be interested in understanding the basics of the purpose for the fill and how to maximize the purpose of fill in the dimensional design.
