foam in the box?

[dirtboi22]

hey im just wondering why people will add foam in their box? does it help sq or somthing?

[Boon]

Uhh foam or fill?

IF you're talking about polyfill/dacron it's to make the box seem larger to the woofer. Helps when you don't have a lot of space to work with.

my bad, your right... fill and thanks

i always wondered how it makes the box "feel" larger to the woofer, and this seemed like a good opportunity to ask?

that has somethin to do with it.

the air movement causes the fill to rub together and make heat. i forgot how that makes the box seem bigger though.

heat makes air expand? seems logical

I believe, now I may be making up some complete bullshit here, so dont quote me, that the fill slows down the back wave, resists air movement, and therefore makes it seem to the sub like it is in a larger enclosure. Maybe this is right?

Now you got it.

Poly Fill simply slows down the wave. Making it travel for a longer period of time, which simulates the effect of traveling a further distance.

So basically, making the box react like a larger box.
