Polyfill

Postby 817boy » Wed Sep 26, 2007 8:15 pm

In about a month i plan on getting either 1 15 in kicker cvx or 2 10 in kicker cvx. I plan on putting them in my backseat of my bmw coupe. I am going to buy a box, for which ever system i end up buying. What is this POLYFILL i keep seeing and hearing about in boxes. Is this worth putting in a sub box. Is there any cons of putting polyfill in the box? Where can i buy polyfill at.

It just makes the box seem slightly larger to the sub, so it tends to go a little lower and maybe sounds a little smoother (that's the simple description). I buy the $2 bag at walmart and keep it in one piece when I take out what I need, then stuff it in. It sticks together that way and I often don't fasten it in at all if it fits good. I fill maybe 2/3 of the box with the fluffy stuff...they tell you the pounds per cf to use if you look it up. I like to leave some air space for the sub to vent, but I had some kicker boxes that were packed factory tight against the sub so who knows. Its what is in pillows and you don't want to compress it keep it fluffed.

In my own experience, in a car audio setting, I could only detect an audible difference when the engine was off. It's so cheap, though, that I continue to use it and just tell myself that I'm 'doing the right thing'. :)

Edit: I guess I should have looked at the date of the original post. Oops...
