    Icon32 Free Air Space

    Hey, guys! I just have a quick question. The best enclosure that I can find for my truck only has 0.93 cubic feet and my sub says that it needs at least 1.00 cubic feet.

    Will I lose a lot of performance because of this? I have looked into building one, but I really can't make it much better than the one I'm looking at due to space.

    Thanks in advance! :-)

    Re: Free Air Space

    Do you think I should add some Poly-Fil or just leave it alone?

    u can shove a little in there cause u will also loose air space due to sub displacement.. don't pack it to tight leave room for sub it may trick sub into sounding like box is .1 cf bigger never know..

    Poli-fil isn't necessary.

    Re: Free Air Space

    If your talking sealed then no difference. And I agree with boomin. No need for poly unless you have the extra few $ to try and see if you like it better with or without. But one sub in a 1cft enclosure I highly doubt you'll see any real difference.
