    What do you mean by 'enclosure'? A room or something else?

    It is fibrefill that they put in to enclosures. Roughly the same as insulation. The main point for using it is to increase the acoustic volume of the enclosure so that the enclosure doesn't have to be massive (relatively speaking of course). For example, a 150litre enclosure stuffed with fibrefill will simulate about 180litres of volume. Usually a max increase of about 25% can be acheived.

    I would've thought that putting that stuff in would reduce the amount of "free" space in the enclosure... Just shows how much I don't know!!!

    okay, so the question is, to insulate or not to insulate....

    my box is 1.82^3(ported). that is what I wanted it to be. So I should not stuff it than? If I do the volume increases, that is not what I want right? What about the advantages it gives like absorbing higher frequencies, do I want it for that?

    Some people say do , some don't.

    I guess there is no for sure answer

    Thanks for all help
