i just made a really nice box for my CVR that i just ordered, and i was wondering if i should put poly fill in there, if i do , how do you do it, cause wouldn't it blow it all out??or what, ive heard about it before, but im not sure.
you can use a wire mesh to hold it in. i don't know exactly how that will change the tuned frequency of the box, but i know it will. poly gives the sub the impression of a 10% larger box. that can throw specs off unless the box is too small to begin with.
i read it has no real benefits in a ported box (build ur ported box to specs in the 1st place) & yep lil pieces will get blown out so putting mess over ur port will also afect how it sounds & eventually it may get clogged like how a A/C filter does .....
Polyfill deals with Thermal Dynamics... (physics) lol NO standing waves inside of a ported box... they fly out the port very fast... Sealed box, u have standing waves.. the polyfill disapates heat, so the subs play like they are in a bigger box.. with less heat..
NO good for ported boxes, how many times is this gonna be asked??
I have heard that it is no good for ported boxes and never use it in mine. But I do see poly fill in some factory home audio speakers that are ported. Like a pair of marantz towers. The box was lined with poly fil, to get rid of standing waves. But there aren't standing waves in a ported box so what gives?
