Modeled stuffing in WinISD (I think). Thoughts?
In my build post, I talk about some of the snafu's I've encountered during the build, specifically the addition of polyfill (dual 6 cubic foot sealed boxes, with about 5.75 internal volume). I started to think if I needed it in the first place, as more than a few said I didnt. I have read countless threads about using fill in the first place (Ricci's article was really good). Anyways, I modeled my driver (FiCar Audio HT-3) to see the difference if I added fill or pillows verses nothing.
5.75 cubic foot
Fsc - 34.74 hz
Qtc - 0.689
109 db @ 20 hz
Fill to get to about 5.33 cubic foot (so a little less than 1/2 pound)
Fsc - 35.55 hz
Qtc - .703
107.8 db @ 20 hz
I am unsure about what the impedance model means or how to read it. I am leaning towards not using any fill at all, or possibly one small pillow. What say any of you?
